What does anconeus mean in anatomy?

What does anconeus mean in anatomy?

The anconeus is a small muscle located at the elbow attaching the humerus and ulna. Although the anconeus muscle is active during elbow extension the importance of the anconeus for the movement itself is probably very small. The Triceps brachii muscle is by far the major muscle responsible for elbow extension.

What is the anconeus muscle?

The anconeus muscle is a triangular-shaped muscle originating posterior to the lateral epicondyle of the humerus and then fanning out broadly for an insertion base on the proximal part of the posterolateral side of the ulna.3,11. From: Morrey’s the Elbow and its Disorders (Fifth Edition), 2018.

Why is it called the anconeus muscle?

The anconeus is a small, triangular muscle of the arm. It is located at the posterior aspect of the elbow, extending from the distal humerus to the proximal ulna.

Anconeus muscle.

Origin Lateral epicondyle of humerus
Action Assists in forearm extension at the elbow joint; Stabilization of elbow joint
Innervation Radial nerve (C7-C8)

How does the anconeus muscle work?

The “anconeus sidekick” is a relatively simple exercise: kneel down alongside a bench, using it to support your upper arm, leaving it at right angles to your body, parallel to the floor. Your forearm should then be hanging straight down.

Where does the anconeus originate from?

lateral epicondyle of the humerus

Anconeus originates on the posterior surface of the lateral epicondyle of the humerus and inserts distally on the superior posterior surface of the ulna and the lateral aspect of the olecranon.
