Question

unit 2 - challenge 2.2: the skeletal system
which type of bone is typically thin and often curved?
a.) sesamoid bone
b.) short bone
c.) long bone
d.) flat bone

Explanation:

Flat bones are typically thin and often curved. They serve to protect internal organs (such as the skull protecting the brain, sternum and ribs protecting the thoracic organs) and provide a broad surface for muscle attachment.
Sesamoid bones (like the patella) are small and embedded in tendons. Short bones (e.g., carpals and tarsals) are roughly cube - shaped. Long bones (such as femur, humerus) have a long shaft (diaphysis) and two ends (epiphyses) and are longer than they are wide.

Answer:

d. Flat bone
