Identify the structure in the diagram below
The Correct Answer is ["Ulna bone"]
The ulna is one of the two bones of the forearm, located on the medial (inner) side of the arm.
It is a long bone that runs parallel to the radius bone, extending from the elbow joint to the wrist joint.
The ulna features several surface landmarks, including the olecranon process, which forms the bony tip of the elbow.
The bone is also involved in the formation of the elbow joint, where it articulates with the humerus bone, and the wrist joint, where it articulates with the radius bone and several carpal bones.
The ulna is an important site for the attachment of muscles involved in forearm and wrist movements.

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.
