Correct Answer is ["The olecranon fossa"]
Explanation
The olecranon fossa is a depression located on the posterior aspect of the distal end of the humerus bone, just above the trochlea.
It is part of the elbow joint and serves as a resting place for the olecranon process of the ulna bone during elbow extension.
The fossa is bordered by the medial and lateral epicondyles of the humerus and is separated from the trochlea by a thin medial ridge.
The olecranon fossa is an important landmark for orthopedic surgeons as it provides access to the distal humerus for surgical procedures, such as total elbow replacement.
Injury to the olecranon fossa can result in fractures or dislocations of the elbow joint.
Correct Answer is D
Explanation
Bone marrow is the soft, spongy tissue that fills the medullary cavity of long bones.
Bone marrow contains hematopoietic stem cells that produce blood cells, as well as fat cells and other supportive cells.
Choice A is incorrect because spongy bone is not the tissue that fills the medullary cavity, but the type of bone tissue that surrounds it.
Spongy bone has a porous structure that provides strength and flexibility to the bone.
Choice B is incorrect because compact bone is not the tissue that fills the medullary cavity, but the type of bone tissue that forms the outer wall of the diaphysis.
Compact bone has a dense and hard structure that provides protection and support to the bone.
Choice C is incorrect because none of these is not a valid answer.
The medullary cavity of long bones does contain a specific type of tissue, which is bone marrow.
