Question

Tom injured his arm while playing. During the examination, bleeding close to the lining of the bone was observed. What is the name of the part that covers the bone and is probably injured?

Answer 1

The periosteum is the membrane lining the bone that is probably injured.

Answer 2

Periosteum

Step-by-step explanation:

The periosteum is composed of a delicate fibrous connective tissue that lines each skeletal element like a sheath, except at the articular cartilage sites. During Tom's examination, bleeding was observed near the periosteum that is probably injured.

The poriosteum has two leaflets, one superficial and one deep in direct contact with the bone. This coating has the function, besides involving, nourishing the external faces of bones and also depositing bone tissue mainly during fracture consolidations forming a great structure for fixation of tendons and ligaments.
