Humerus Flashcard

Front

What is the lesser tubercle?

Back

The lesser tubercle is a small, prominent projection on the humerus, located on the anterior side, serving as an attachment point for muscles.

Front

What is the anatomical neck of the humerus?

Back

The anatomical neck is the area just below the head of the humerus, marking the transition between the head and the shaft.

Front

What is the head of the humerus?

Back

The head of the humerus is the rounded, ball-like structure at the proximal end of the humerus that fits into the glenoid cavity of the scapula.

Front

What is the greater tubercle?

Back

The greater tubercle is a large, lateral projection on the humerus that serves as an attachment point for several rotator cuff muscles.

Front

What is the capitulum?

Back

The capitulum is a rounded knob on the distal end of the humerus that articulates with the head of the radius.

Front

What is the surgical neck of the humerus?

Back

The surgical neck is the area just below the tubercles of the humerus, commonly fractured in humeral injuries.

Front

What is the trochlea?

Back

The trochlea is a spool-shaped structure on the distal end of the humerus that articulates with the ulna.

Front

What is the medial epicondyle?

Back

The medial epicondyle is a bony prominence on the inner side of the distal humerus, serving as an attachment point for forearm flexor muscles.

Front

What is the lateral epicondyle?

Back

The lateral epicondyle is a bony prominence on the outer side of the distal humerus, serving as an attachment point for forearm extensor muscles.

Front

What is the intertubercular groove?

Back

The intertubercular groove is a groove between the greater and lesser tubercles of the humerus that houses the tendon of the biceps brachii.
