Question

question 3 1 pts the type of bone marrow that is found in the diaphysis of long bones is yellow bone marrow true false question 4 1 pts the structures that permit tendons to slide easily across a moving joint such as synovial joint are: bursae ligaments the bones themselves tendons

Explanation:

Question 3

Long bones have a diaphysis (shaft) and epiphyses (ends). The diaphysis of long bones contains yellow bone marrow (composed mainly of fat), while red bone marrow is more common in the epiphyses (in adults) and in the diaphyses of children. So the statement is true.

• Bursae are fluid - filled sacs that reduce friction between structures like tendons and bones or other tendons, allowing tendons to slide easily across moving joints (like synovial joints).
• Ligaments connect bone to bone, not for tendon sliding.
• Bones themselves don't facilitate tendon sliding in this way.
• Tendons are the structures being helped to slide, not the ones facilitating the sliding. So the correct structure is bursae.

Answer:

True
