Question

Which of the following pairings is/are correct?

a. membranes of bones: periosteum and endosteum

b. periosteum: hasan outer osteogenic layer andan inner fibrous layer

c. endosteum: delicate membrane that covers internal surfaces of bone

Answer 1

The correct pairings are that the periosteum is a fibrous membrane with an osteogenic layer and an inner fibrous layer, and the endosteum is a delicate membrane covering the internal surfaces of bones.

Step-by-step explanation:

The pairing of the membranes of bones: periosteum and endosteum is correct. The periosteum is a fibrous membrane that covers the outer surface of bones, except where the epiphyses meet other bones to form joints, and contains blood vessels, nerves, and lymphatic vessels that nourish compact bone.

Tendons and ligaments also attach at the periosteum. The periosteum has an outer osteogenic layer and an inner fibrous layer. The endosteum is a delicate membranous lining that covers internal surfaces of bone, such as the medullary cavity, where bone growth, repair, and remodeling occur.
