Learning Objective
I can analyze the structure and function of the skeletal system.
- 1
Your axial bones are found along your body’s vertical axis, while your appendicular bones make up your limbs.
- 2
Osteoblasts are bone-building cells that secrete collagen and enzymes to construct bones, while osteoclasts break down bone tissue through a process called resorption.
- 3
In microgravity, osteoclasts increase their rate of bone resorption, while osteoblasts decrease bone formation, leading to bone loss in astronauts.
