Anconeus muscle

This tutorial covers the anconeus muscle, detailing its origin, insertion, innervation, and function. The anconeus is a small triangular muscle at the elbow, originating from the lateral epicondyle of the humerus and inserting at the olecranon of the ulna. It is innervated by the radial nerve and functions similarly to the triceps, aiding in forearm extension and stabilizing the ulna. The video emphasizes the muscle's role in preventing hyperextension damage and offers additional resources for further learning.

Where is the anconeus muscle located?

• At the shoulder

• At the elbow

• At the wrist

• At the knee

Which nerve supplies the anconeus muscle?

• Musculocutaneous nerve

• Radial nerve

• Median nerve

• Ulnar nerve

How is the anconeus muscle related to the triceps?

• They are morphologically and functionally separate

• They have no functional relationship

• They are often blended together

• They are supplied by different nerves

What is one of the primary functions of the anconeus muscle?

• Rotation of the shoulder

• Extension of the forearm

• Flexion of the forearm

• Flexion of the wrist

What additional role does the anconeus muscle play during forearm pronation?

• Extending the wrist

• Flexing the elbow

• Stabilizing the ulna

• Rotating the shoulder
