Question

The endosteum is located _____ a bone.

Select one:
a. inside
b. at distal end
c. covering
d. at proximal end

Answer 1

The endosteum is located inside a bone, lining the medullary cavity, and is essential for bone growth, repair, and remodeling.

Step-by-step explanation:

The endosteum is located inside a bone. The endosteum is a delicate membranous lining of the medullary cavity of bones, where bone growth, repair, and remodeling occur. While the periosteum forms the outer surface of bone, the endosteum lines the medullary cavity from the inside. The term "endosteum" comes from the Greek words "end" meaning "inside" and "oste" meaning "bone", signaling its internal location. The periosteum contains blood vessels, nerves, and lymphatic vessels that nourish the compact bone, while the endosteum plays a critical role in the growth and health of bones.
