c a bone that formsin the cranium in response to trauma
d a bone made ofhyaline cartilage
e a bone made ofdense regular connective tissue

Explanation:

Define sesamoid bones

Identify function and development

They develop in response to physical stress and friction to protect tendons from wear and tear.

Evaluate the given options

• Option A: Incorrect, they form in tendons, not cartilages.
• Option B: Correct, they form within tendons in response to stress.
• Option C: Incorrect, cranial bones are flat bones, not sesamoid.
• Option D: Incorrect, bones are made of osseous tissue, not hyaline cartilage.
• Option E: Incorrect, tendons are made of dense regular connective tissue, but bones are osseous tissue.

Answer:

• A A bone growingwithin some cartilages in response to pressure
• B A bone that formswithin some tendons in response to stress (Correct answer)
• C A bone that formsin the cranium in response to trauma
