Anatomy and Physiology10 CardsCreated 4 months ago

This deck covers the key concepts of the skeletal system, including the structure, functions, and differences in bone types and skeletal regions.

What is the difference between the axial and appendicular skeleton?

We are composed of one skeleton that can be divided into two major regions, the axial and appendicular skeleton. The axial skeleton makes up our central axis and consists of the following bones: skull, vertebrae, ribs and sternum. The appendicular skeleton consists of the limbs and girdles.

What are the five functions of bones?
1. Support the body 2. Protects soft organs 3. Allow movement due to attached skeletal muscles 4. Storage 5. Blood cell formation within marrow
What is the difference between spongy and compact bone?
Spongy bone is porous and lightweight, while compact bone is dense and strong.
What are the four shapes and sizes of bones? What are examples of each?
Long (femur), short (carpals), flat (skull), and irregular (vertebrae) bones.
What is the function of the various parts of a long bone?
They support body weight, produce blood cells, and store minerals.
How does the skeleton, and bones, change through our life?
Bones grow, harden, and remodel over time, becoming brittle with age.
