Hether DSC anatomy 1 midterm 1 of 2

Summary

This review session for the Anatomy 1 midterm at Daytona State College covers essential topics from chapters on the axial and appendicular skeletons. Key concepts include body planes, anatomical positions, and cell structures, alongside the use of microscopes and histology. The review emphasizes understanding the organization of the human body, cellular components, tissue types, and the skeletal system, including bone classifications and major landmarks. Students are guided on what to expect on the exam, focusing on identification and application of anatomical knowledge, ensuring they are well-prepared for practical assessments.

Takeaways

• 📏 Understand the body planes: coronal (divides front and back), transverse (divides upper and lower), and mid-sagittal (divides into equal right and left halves).
• 🦠 Be familiar with the parts of a microscope, including the course and fine knobs, stage, and ocular lenses, as questions about these will appear on the test.
• 🔬 Total magnification is calculated by multiplying the objective lens by 10 (the eyepiece), with a minimum of 40x and a maximum of 1000x.
• 🧬 Know the structure and function of the cell, including the phospholipid bilayer, organelles, and the process of mitosis.
• 📊 Review the phases of mitosis: interphase, prophase, metaphase, anaphase, and telophase, and their key characteristics.
• 🧪 Familiarize yourself with histology concepts, including the different types of epithelial tissue: squamous, cuboidal, columnar, and ciliated.
• 🦴 Recognize the types of connective tissues, including loose, dense, and specialized connective tissues, as well as skeletal, cardiac, and smooth muscle.
• 💀 Understand the differences between various bone types (long, short, flat, irregular, sesamoid) and their roles in the body.
• 🔍 Be able to identify major bones in the axial and appendicular skeleton, including the vertebrae, clavicle, scapula, femur, tibia, and fibula.
• 🧪 Review the layers of the skin: epidermis, dermis, and hypodermis, and the associated structures such as hair follicles, sweat glands, and nerve endings.

Q & A

What is the focus of the midterm exam in the Anatomy lab review?

The midterm exam will cover content from chapters one through the axial and appendicular skeleton.

Which plane divides the body into anterior and posterior sections?

The coronal plane divides the body into anterior (front) and posterior (back) sections.

What structure divides the thoracic and abdominal cavities?

The diaphragm divides the thoracic and abdominal cavities.

What are the parts of the microscope that students need to identify for the exam?

Students need to identify parts such as the coarse knob, fine knob, stage, substage light, condenser, iris diaphragm, objective lenses, rotating nosepiece, ocular lenses, arm, and base.

What is the total magnification formula for a microscope?

Total magnification is calculated by multiplying the objective lens magnification by 10 (the magnification of the eyepiece).

What are the three types of epithelial tissue mentioned in the review?

The three types of epithelial tissue mentioned are squamous, cuboidal, and columnar.

How are the layers of the epidermis and dermis described?

There are five layers of the epidermis and two layers of the dermis, although students do not need to name them for the exam.

What types of connective tissue should students be familiar with?

Students should be familiar with loose connective tissue, dense connective tissue, and specialized connective tissue.

What are the two main parts of the appendicular skeleton?

The two main parts of the appendicular skeleton are the pectoral girdle (shoulder area) and the pelvic girdle (hip area).

What is the role of bones in the human body as discussed in the review?

Bones provide structure, protect major organs, store minerals and fat, produce red blood cells, and serve as levers for muscle movement.
