Humerus Flashcards
(15 cards)
What is the anatomical neck of the humerus?
The anatomical neck is located just below the head of the humerus.
What are the major tubercles of the humerus?
The major tubercles are the greater tubercle and the lesser tubercle.
What is the intertubercular groove?
The intertubercular groove (sulcus) is found between the greater and lesser tubercles.
What is the surgical neck of the humerus?
The surgical neck is located below the tubercles and is a common site for fractures.
What is the deltoid tuberosity?
The deltoid tuberosity is a roughened area on the lateral side of the humerus.
What is the body (shaft) of the humerus?
The body (shaft) is the long, cylindrical part of the humerus.
What is the lateral supracondylar ridge?
The lateral supracondylar ridge is a bony prominence on the lateral side of the humerus.
What is the radial fossa?
The radial fossa is a shallow depression on the anterior aspect of the humerus.
What is the capitulum?
The capitulum is a rounded knob on the distal end of the humerus that articulates with the head of the radius.
What are the olecranon and coronoid fossae?
The olecranon fossa is a large depression on the posterior side, while the coronoid fossa is a smaller depression on the anterior side.
What are the medial and lateral epicondyles?
The medial epicondyle is located on the inner side, and the lateral epicondyle is on the outer side of the humerus.
What is the trochlea?
The trochlea is a spool-shaped structure at the distal end of the humerus that articulates with the ulna.
What is the coronoid process of the ulna?
The coronoid process is a projection on the ulna that fits into the coronoid fossa of the humerus.
What is the olecranon of the ulna?
The olecranon is the bony prominence of the ulna that fits into the olecranon fossa of the humerus.
What is the head of the radius?
The head of the radius is the rounded top of the radius that articulates with the capitulum of the humerus.
