Nerves of nasal cavity (preview) - Human Anatomy | Kenhub
Summary
TLDRIn this Kenhub tutorial, Nicole explores the nerves of the nasal cavity, highlighting its anatomy and functions. The nasal cavity, with its nasal septum, warms, humidifies, and filters air, housing the olfactory epithelium for smell. Key structures like the sphenoidal sinus and maxilla are identified. The tutorial also touches on clinical notes, aiming to educate and engage anatomy enthusiasts.
Takeaways
- 👃 The nasal cavity is part of the respiratory system, with two paired cavities located on either side of the nasal septum.
- 🌡️ The primary function of the nasal cavity is to warm, humidify, and filter the air as it enters through the nostrils.
- 🕷️ The nasal cavity's ability to filter air is due to the hair and mucous lining of its internal walls, which remove allergens before the air reaches the lungs.
- 👃 The olfactory epithelium, located in the nasal cavity, is responsible for the sense of smell.
- 💧 The nasal cavity also produces mucus to aid in filtering the air.
- 🦴 The nasal septum is composed of septal cartilage and bones such as the vomer and ethmoid bone.
- 🦴 The maxilla and palatine bones contribute to the formation of the hard palate, which separates the nose from the mouth.
- 🔍 The tutorial includes an image of the nasal cavity, highlighting structures like the nasal septum, lateral wall, sphenoidal sinus, and maxilla.
- 📚 The tutorial also discusses relevant clinical notes after covering the anatomy of the nasal cavity.
- 🎥 The full tutorial, along with more videos, quizzes, articles, and atlas sections, is available to premium members on Kenhub.com.
Q & A
What is the primary focus of the tutorial presented by Nicole from Kenhub?
-The tutorial primarily focuses on the nerves of the nasal cavity.
What are the three main functions of the nasal cavity?
-The three main functions of the nasal cavity are to warm, humidify, and filter air as it enters the nostrils; to hold the olfactory epithelium, which is responsible for the sense of smell; and to produce mucus that helps filter the air.
How does the nasal cavity warm and filter the air?
-The nasal cavity warms and filters the air due to the hair and mucous lining of the internal walls, which remove allergens before the air passes into the lungs.
What is the role of the olfactory epithelium in the nasal cavity?
-The olfactory epithelium is the organ that contains the receptors for the sense of smell.
What are the two paired cavities found on either side of the nasal septum?
-The two paired cavities found on either side of the nasal septum are the nasal cavities.
What are the nasal cavities separated from each other by?
-The nasal cavities are separated from each other by a nasal septum.
What is the composition of the nasal septum?
-The nasal septum is composed of septal cartilage and two bones of the skull, the vomer and the ethmoid bone.
How does the nasal cavity contribute to the production of mucus?
-The nasal cavity contributes to the production of mucus, which helps filter the air entering the nose.
What is the term for the openings at the beginning of the nasal cavity?
-The openings at the beginning of the nasal cavity are called the nares or nostrils.
What is the term for the area that separates the nose from the mouth?
-The area that separates the nose from the mouth is called the hard palate.
What additional resources are available to Kenhub premium members?
-Kenhub premium members have access to more videos, quizzes, related articles, and atlas sections.
Outlines
👃 Introduction to the Nasal Cavity Anatomy and Tutorial Overview
In this introductory section, Nicole from Kenhub welcomes viewers to a tutorial focused on the nerves of the nasal cavity. The video will explore various structures like the nasal septum, lateral wall, sphenoidal sinus, maxilla, and some upper teeth, with clinical notes to follow. Before delving into the nerves, the section touches on the nasal cavity's role and anatomy, highlighting the mid-sagittal view of the skull.
💨 The Functions of the Nasal Cavity
This section describes the three main functions of the nasal cavity: (1) warming, humidifying, and filtering air through the nostrils (nares), aided by the mucous and hair linings; (2) serving as the location for the olfactory epithelium, responsible for the sense of smell; and (3) producing mucus, which helps filter the air before it reaches the lungs.
🧠 Anatomy of the Nasal Cavity
This portion focuses on the anatomy of the nasal cavity. Each person has two nasal cavities separated by the nasal septum, which consists of septal cartilage and two bones: the vomer and ethmoid. These bones, although not visible in the image, descend from the cribriform plates. The maxilla and palatine bone form part of the nasal cavity and separate it from the mouth via the hard palate. The section also refers to the hard palate's role, highlighted in green in the diagram.

hey everyone it's nicole from kenhub and
welcome to our tutorial on the nerves of
the nasal cavity
in this tutorial we're going to be
looking at all the nerves shown on this
image of the nasal cavity which as you
can see
has a bit of the nasal septum turned
upwards around here
the lateral wall of the nasal cavity
just here the sphenoidal sinus
and the maxilla with some of the upper
teeth down here
and as we go through the nurse we'll
just point out a few other structures
here and
there and of course after talking about
these nerves at the end of the tutorial
we'll also go over some
relevant clinical notes but first before
we get on to the nerves of the nasal
cavity we're just going to begin with a
little bit of a chat about the nasal
cavities function
so we're just going to begin with our
image of our mid-sagittal section of the
skull
and here we can see the nasal cavity as
we saw it above
as well as the bones of the skull and we
might as well point them out while we're
here so
our frontal parietal
temporal and occipital bones and the
nasal cavities are two paired cavities
found on either side of the nasal septum
and these cavities begin at the nares or
the nostrils
and end at the pharynx and the nasal
cavity has
three main functions the first of which
being its ability to warm
humidify and filter air as it enters the
nairs and this ability to warm and
filter the air is due to the hair and
mucous lining of the internal walls of
the nasal cavity which remove allergens
from the air before it passes into
the lungs the nasal cavity also holds
the organ that holds the receptors for
the sense of smell
the olfactory epithelium contributing to
its
second function and finally the nasal
cavity also produces mucus which as i
just mentioned
helps filter the air entering the nose
so let's have a brief look at the
anatomy of the nasal cavity and as i
mentioned earlier we each have
two nasal cavities each separated from
each other by a
nasal septum and the nasal septum which
is pointed out by the green arrow just
here
is made of septal cartilage as well as
two bones of the skull
and these two bones which are the voma
and the ethmoid bone
can't be seen in this image but they
would be located behind the mucosa that
appears to be covering the bones and the
cartilage
and these two bones also descend and
arise from the cripper form plates
the maxilla and the palatine bone which
are bones of the skull
the nose as we can see in the image is
separated from the mouth
by the hard palate which is also formed
by parts of the maxilla and palatine
bone
and is highlighted in green
this video is not over yet continue
