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 ["Clavicular notch"]
Explanation
The clavicular notch, also known as the sternal notch, is a shallow, V-shaped depression located at the superior aspect of the sternum, which is the long, flat bone in the center of the chest.
The clavicular notch serves as the articulation site for the medial end of the clavicle bone, forming the sternoclavicular joint.

Correct Answer is ["Foramen transversarium"]
Explanation
The foramen transversarium is a canal that is found in the transverse process of the cervical vertebrae, C1 through C7.
It is an opening in the bone that allows the passage of the vertebral artery, vertebral vein, and sympathetic nerves.
The vertebral artery passes through the foramen transversarium in C1-C6 vertebrae, while the vertebral vein passes through the foramen in C1-C7 vertebrae.
The sympathetic nerves pass through the foramen in C1-C6 vertebrae as well.
Injuries to the foramen transversarium can cause damage to the vertebral artery and vein, leading to a variety of symptoms, including dizziness, headaches, and visual disturbances.
