Question 1 of 5
In which structure are osteoclasts and osteoblasts found?
Correct Answer: A
Rationale: Osteoblasts (bone-forming) and osteoclasts (bone-resorbing) are in the periosteum, the membrane around bones. Lacunae hold osteocytes, not these cells. Answer is A, per the document.
Question 2 of 5
Which of the following is an example of a synovial joint? The joint between the:

Question 4 of 5

Rationale: Synovial joints are freely movable, with hyaline cartilage on bone ends reducing friction (unlike fibrous or cartilaginous joints). A and B are wrong types, C is cartilaginous. Answer is D, per the document.
Question 5 of 5
What is the role of hyaline cartilage in the body?
Correct Answer: C
