Supraglenoid Tubercle

The Supraglenoid Tubercle is a part of the scapula, or shoulder blade, in the human body. It is a small bony projection located on the superior margin of the glenoid cavity. This tubercle serves as the attachment point for the long head of the biceps brachii muscle.

Etymology[edit | edit source]

The term "Supraglenoid" is derived from the Latin words "supra," meaning above, and "glenoid," referring to the glenoid cavity of the scapula. "Tubercle" is a term used in anatomy to describe a small, rounded projection or protuberance on a bone.

Anatomy[edit | edit source]

The Supraglenoid Tubercle is located on the superior margin of the glenoid cavity, which is the part of the scapula that forms the ball and socket joint with the humerus. This tubercle is the point of attachment for the long head of the biceps brachii muscle, one of the major muscles of the upper arm.

Clinical Significance[edit | edit source]

Injuries or abnormalities of the Supraglenoid Tubercle can affect the function of the biceps brachii muscle, potentially leading to weakness or loss of function in the arm. Such conditions may be diagnosed through physical examination or imaging studies such as MRI.
