What is the deltoid tuberosity?

Back

A roughened area on the lateral aspect of the humerus where the deltoid muscle attaches.

Front

What is the lateral epicondyle?

Back

A bony prominence on the outer side of the humerus, serving as an attachment point for muscles of the forearm.

Front

What is the lesser tubercle?

Back

A small, rounded projection on the anterior surface of the humerus, providing attachment for the subscapularis muscle.

Front

What is the greater tubercle?

Back

A large, prominent projection on the humerus, serving as an attachment point for the rotator cuff muscles.

Front

What is the medial epicondyle?

Back

A bony prominence on the inner side of the humerus, serving as an attachment point for forearm flexor muscles.

Front

What is the trochlea?

Back

A spool-shaped structure on the humerus that articulates with the ulna at the elbow joint.

Front

What is the capitulum?

Back

A rounded knob on the humerus that articulates with the head of the radius.

Front

What is the intertubercular groove?

Back

A groove between the greater and lesser tubercles of the humerus, allowing passage for the tendon of the biceps brachii.

Front

What is the anatomical neck of the humerus?

Back

A slight constriction below the head of the humerus, marking the boundary between the head and the shaft.

Front

What muscles attach to the greater tubercle of the humerus?

Back

The supraspinatus, infraspinatus, and teres minor muscles attach to the greater tubercle.
