Elbow Anatomy II

Front

What is the function of the ulnar collateral ligament in the elbow?

Back

The ulnar collateral ligament provides stability to the elbow joint, particularly during activities that involve throwing or overhead motions.

Front

Where does the biceps brachii muscle attach at the elbow?

Back

The biceps brachii muscle attaches to the radial tuberosity on the radius.

Front

What is the anatomical position of the medial epicondyle?

Back

The medial epicondyle is located on the inner side of the elbow, at the distal end of the humerus.

Front

What is the shape and location of the ulnar collateral ligament?

Back

The ulnar collateral ligament is triangular in shape and runs from the medial epicondyle of the humerus to the proximal ulna.

Front

What is the primary role of the radius in elbow movement?

Back

The radius allows for rotation of the forearm and is involved in flexion and extension at the elbow joint.

Front

Identify the structure that is commonly referred to as the 'funny bone'.

Back

The 'funny bone' refers to the ulnar nerve, which runs near the medial epicondyle.

Front

What type of joint is the elbow classified as?

Back

The elbow is classified as a hinge joint, allowing for flexion and extension.

Front

What are the two main movements allowed at the elbow joint?

Back

The two main movements at the elbow joint are flexion and extension.

Front

What is the significance of the lateral epicondyle in elbow anatomy?

Back

The lateral epicondyle serves as an attachment point for several muscles and ligaments, including the radial collateral ligament.

Front

What is the role of the annular ligament in the elbow?

Back

The annular ligament encircles the head of the radius, allowing for its rotation and providing stability to the proximal radioulnar joint.
