Correct Answer is ["Surgical neck of the humerus"]
Explanation
The surgical neck of the humerus is a part of the bone that lies below the greater and lesser tubercles and is a common site for fractures.
It is the most constricted part of the humerus and marks the transition between the expanded proximal end and the narrower shaft.
The neck is located between the tuberosities and is the site of attachment for the capsule of the shoulder joint.
The axillary nerve and posterior circumflex humeral artery also pass through the surgical neck.
The anatomy of the surgical neck is important in the diagnosis and treatment of shoulder injuries and fractures.
