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?
a. yellow bone marrow
b. periosteum
c. trabeculae

Explanation:

• Yellow bone marrow: It is inside the bone, not covering it.
• Periosteum: A membrane covering the bone. It has blood vessels, so injury can cause bleeding.
• Trabeculae: Internal bone structure (spongy bone part), not a covering.
• Cartilage: Smooths bone ends (like in joints), not the main covering with blood - vessel - rich lining as described.

Answer:

B. periosteum
