Q & A
What is the standard anatomical position?
-The standard anatomical position is a body orientation used to describe anatomical planes, sections, and directional terms. It involves standing upright with the head and eyes directed straight ahead, upper limbs hanging down at the sides with palms facing forward, and lower limbs together with feet flat on the ground facing forward.
Why is the standard anatomical position important?
-The standard anatomical position is important because it provides a universal and consistent way of discussing anatomy, creating clear reference points when describing anatomical positions or using anatomical terms.
What is the difference between body planes and body sections?
-Body planes are imaginary lines drawn through an upright body in anatomical position that divide the body into sections or portions. Body sections, on the other hand, are the portions of the body created by the cut from the plane.
How many main body planes are there and what are they?
-There are three main body planes: the sagittal plane, the coronal plane, and the transverse plane.
What does the abbreviation 'SCT' stand for and how does it help in remembering the main body planes?
-The abbreviation 'SCT' stands for Sagittal, Coronal, and Transverse planes. It helps in remembering the order and the names of the three main body planes.
What is the midsagittal plane and how is it different from a parasagittal plane?
-The midsagittal plane is a specific sagittal plane that runs through the midline of the body, dividing it into equal right and left portions. It is also known as the median plane. A parasagittal plane, however, is any off-center sagittal plane that divides the body into unequal right and left portions and runs parallel to the midsagittal plane.
How can the terms 'sagittal' and 'side view' help in remembering the sagittal plane?
-The terms 'sagittal' and 'side view' both start with the letter 'S', which can help in remembering that when a cut is made through the sagittal plane, it provides a side view of the body.
What is the coronal plane and how does it divide the body?
-The coronal plane, also known as the frontal plane, is a vertical plane that runs from top to bottom and right to left, dividing the body into a front section and a back section.
What is the transverse plane and how does it provide a top view of the body?
-The transverse plane, also known as the axial or horizontal plane, is a horizontal line that runs from right to left and front to back, dividing the body into a top section and a bottom section, thus providing a top view of the body.
What are longitudinal planes and how are they related to the transverse plane?
-Longitudinal planes are any planes that are perpendicular to the transverse plane. Both the sagittal and coronal planes run perpendicular to the transverse plane, making them examples of longitudinal planes.
What is an oblique plane and how does it differ from the major body planes?
-An oblique plane is any plane that is not horizontal or vertical, meaning it does not fall into the categories of sagittal, coronal, or transverse planes. It can run at any angle through the body as long as it is not aligned with the major planes.

š§ Introduction to Anatomical Position and Body Planes
This paragraph introduces the concept of the anatomical position, which is a standardized body orientation used to describe anatomical planes and sections, as well as directional terms. The anatomical position is depicted through an image of a man standing upright with specific alignments of limbs and hands. It emphasizes the importance of this position in providing a universal reference for anatomical discussions. The paragraph also distinguishes between body planes and sections, explaining that planes are imaginary lines that divide the body into sections, allowing for the description of anatomical structures from different views.
š Exploring Major Body Planes and Sections
This paragraph delves into the specifics of the three main body planes: sagittal, coronal, and transverse, using the acronym 'SCT' to aid memorization. The sagittal plane is described as a vertical division creating right and left sections, with the midsagittal plane being the central line splitting the body into equal halves. The coronal plane, also known as the frontal plane, is another vertical division that separates the body into front and back sections. Lastly, the transverse plane, or axial plane, is a horizontal division that cuts the body into top and bottom sections. The paragraph also explains how these planes provide different views of the body and mentions additional planes such as longitudinal and oblique, which run perpendicular to the transverse plane or at angles not aligned with the major planes, respectively.

Transcripts
Welcome back to the channel whereĀ medical and science topics are made easy.
Today weāre going to talk about the anatomicalĀ position, along with body planes and sections.
Youāre going to learn several tricksĀ that will help you remember the differentĀ Ā
planes and sections of the body, soĀ make sure to watch until the end.
Youāll also want to hit that subscribeĀ button because the next video is on anatomyĀ Ā
directional terms which will take what weĀ learn today and show you how itās used.
Finally, make sure to turn on theĀ captions down below and read along.Ā Ā
This will help you remember everything.
In order to understand the different body planes
we need to learn what theĀ standard anatomical position is.
The standard anatomical position refers to theĀ body orientation used to describe things like
anatomical planes or sections whichĀ we are going to talk about in this video
as well as anatomical directional termsĀ which weāll talk about in the next video.
It basically provides a universal,Ā consistent way of discussing anatomy
and it creates clear referenceĀ points when describing anatomicalĀ Ā
positions or using anatomical terms.
We can use the picture of the man toĀ illustrate the standard anatomical position.
The correct position is standing upright,
with the head and eyes directed straight ahead.
The upper limbs are hanging down at the sides,
and slightly away from the trunk soĀ the hands are not touching the sides.
The palms are facing forward,
and the thumbs are pointing away from the body.
The lower limbs are together,
and the feet are flat onĀ the ground facing forward.
When someone is in the anatomical position, right and leftĀ refer to the patientās right and left sideĀ Ā
and not as if you were looking at the patient.
In other words, if you were looking at theĀ patient their right side will be your left sideĀ Ā
and their left side will be your right side asĀ indicated by the labels āRā and āLā on the screen.
Now that we have a good understandingĀ of the anatomical position,Ā Ā
letās talk about the different planes of the body.
The terms body planes and sectionsĀ are often used interchangeablyĀ Ā
but they actually have differentĀ definitions, so letās take a look at them.
First, what is a body plane?
Body planes are imaginary lines drawn throughĀ an upright body that's in anatomical position.
The major planes or imaginary linesĀ can run vertically or horizontally.
And they divide the bodyĀ into sections or portions.
For example, the planes might divideĀ the body into right and left sections,Ā Ā
upper and lower sections, or front and backĀ sections depending on the direction of the cut.
The body planes provide differentĀ views or sections of the body,Ā Ā
which then allows us to describe the location orĀ direction of anatomical structures or features.
Now that we know what body planesĀ are, how about body sections?
Well, we hinted to it earlier.
Sections are the portions of the bodyĀ created by the cut from the plane.
So again that could be right and leftĀ sections, upper and lower sections,Ā Ā
or front and back sectionsĀ depending on the slice of the plane.
The simple way to think aboutĀ the terms is the plane is theĀ Ā
imaginary line that cuts the body into sections,Ā Ā
and this allows us to look at different views ofĀ the body depending on the direction of the cut.
Let's go through the major body planes and take a look at some example sections
and all of this will begin to make sense.
There are 3 main body planes and then a coupleĀ minor ones weāre going to talk about at the end.
A simple trick to rememberĀ the 3 main body planes is to
take the word section, since weāre talking aboutĀ body planes and sections, and abbreviate it "SCT".
This will help you rememberĀ sagittal, coronal, and transverse.
The sagittal plane is the green cut labeledĀ āSā on the image, the coronal plane is theĀ Ā
blue cut labeled āCā, and the transverseĀ plane is the yellow cut labeled āTā.
If we use the abbreviation SCT, you can alsoĀ remember the first 2 are vertical planes whichĀ Ā
are sagittal and coronal, and the last one isĀ a horizontal plane which is the transverse.
Weāre now going to talk about eachĀ plane starting with the sagittal plane.
As we mentioned earlier,
the sagittal plane is one of the vertical planes.
It's an imaginary line that runs from top to bottom and front to back.
It divides the body into a rightĀ section and a left section.
The midsagittal plane is the specificĀ sagittal plane that runs through exactlyĀ Ā
the midline of the body and it divides theĀ body into equal right and left portions.
It is also known as the median plane.
Mid,Ā median, and middle all start with the letter "M"
and this can help you remember the midsagittal planeĀ runs right down the middle or midline of the body.
The pictures on your screen areĀ examples of a midsagittal plane.
A parasagittal plane is any ofĀ the sagittal planes off-centerĀ Ā
and it divides the body intoĀ unequal right and left portions.
Parasagittal planes run parallelĀ or alongside the midsagittal planeĀ Ā
but are not in the midline asĀ we can see in the new picture.
Remember in our medical prefixĀ video we said that the prefix āparaāĀ Ā
means alongside, beside, or nearby.
So it makes sense that the parasagittal planeĀ Ā
is a sagittal plane that runsĀ alongside the midsagittal plane.
An easy way to remember which planeĀ is the sagittal plane is to think of
sagittal and side view. TheyĀ both start with the letter āSā.
And when you make a cut through the sagittalĀ plane, you are looking at a side view of the body.
Letās take a look at some examplesĀ to make sure we understand this.
If we take the picture of the man
and make a cut through the midsagittal plane,
and then spin the right andĀ left sections that we just cut,
you can see we are lookingĀ at a side view of the body.
In other words, these are examples of sagittal sections that were cut through the sagittal plane.
You might also remember from theĀ video on cranial bones and suturesĀ Ā
that there is a suture called the sagittal suture.
It gets its name because the sagittal sutureĀ runs from front to back in the sagittal plane.
It is where the right and leftĀ parietal bones of the skull meet.
So this could help you rememberĀ the sagittal plane as well.
Moving on to the coronal plane,Ā Ā
this is the āCā in our abbreviation SCT whichĀ helps us remember the 3 major planes of the body.
The coronal plane is alsoĀ called the frontal plane.
And as we mentioned earlier,Ā itās also a vertical line.
The imaginary line runs from top to bottom and right to left.
It divides the body into a frontĀ section and a back section.
The easy way to remember the frontal planeĀ is to again use the name. The frontal planeĀ Ā
will give you a front view of the body as itĀ divides the body into front and back portions.
And just to review, remember the sagittalĀ plane will give you a side view of the bodyĀ Ā
and they both start with the letter āSā.
You might also remember from theĀ video on cranial bones and sutures
that there is a suture called the coronal suture.
It gets its name because the coronal sutureĀ runs from right to left in the coronal plane.
It is where the frontal andĀ parietal bones of the skull meet.
And this could help you remember the coronal plane as well.
Finally we have the transverse plane,Ā which is the āTā in our abbreviationĀ Ā
SCT to help us remember theĀ 3 major planes of the body.
The transverse plane is also calledĀ the axial plane or horizontal plane
which makes sense because it is a horizontal line.
You can remember the āXā in axialĀ to help you remember the transverseĀ Ā
plane runs along the āXā axisĀ which is the horizontal axis.
The transverse plane runs fromĀ right to left and front to back.
And it divides the body into a topĀ section and a bottom section.
The easy way to remember the transverse planeĀ is to again use the name. The transverse planeĀ Ā
will give you a top view of the body as itĀ divides the body into upper and lower portions.
And just to review the frontal planeĀ will give you a front view of the body.
And the sagittal plane will giveĀ you a side view of the body.
Here are a couple more tricks toĀ remember the transverse plane.
If you divide the body into a top andĀ bottom section using a transverse plane,
you will be left with anĀ upper body shaped like a āTā
and a lower body shaped like an upside down āVā
and the T and V can help you remember transverse.
We also learned in our medical prefixĀ video that the prefix ātransā means across.
And finally, we said the transverse planeĀ is also called the horizontal plane.
You can think of the horizon for horizontal planeĀ Ā
and this will help you rememberĀ that it goes across horizontally.
There are a couple otherĀ planes you might hear about.
The first term is a longitudinal plane.
A longitudinal plane is any plane thatĀ is perpendicular to the transverse plane.
We can see in our diagram thatĀ the sagittal and coronal planesĀ Ā
run perpendicular to the transverse plane.
Therefore, both the coronal and sagittalĀ planes are examples of longitudinal planes.
A simple trick to remember longitudinalĀ planes is to think of the globeāsĀ Ā
longitudinal lines that run up andĀ down and this will help you rememberĀ Ā
the longitudinal planes run verticallyĀ or perpendicular to the transverse plane.
Finally, you might also hearĀ of planes that are oblique.
An oblique plane is any plane thatĀ is not horizontal or vertical.
In other words, an oblique plane is anyĀ plane that is not in any of the sagittal,Ā Ā
coronal, or transverse planes.
They can run at any angle through the body asĀ long as they are not horizontal or verticalĀ Ā
as that would mean that they areĀ one of the other major planes.
You can think of your obliqueĀ muscles that travel at an angle.
Or you can think of oblique and odd,Ā which both start with the letter āOāĀ Ā
and this can help you remember oblique planes areĀ odd and travel at strange angles.
Hopefully this helped you betterĀ understand the anatomical positionĀ Ā
along with body planes and sections.
