Elbow Joint Anatomy and Function

The video tutorial explores the anatomy of the elbow, focusing on the ligaments and joints. It begins with an overview of the elbow's ligaments, including the ulnar and radial collateral ligaments, and the annular ligament. The instructor dissects these ligaments, demonstrating their relationships and functions. The video also covers the proximal radio-ulnar joint, highlighting its role in pronation and supination. The tutorial concludes with a summary and an invitation to explore more resources on gillheadley.com.

What is the primary focus of the initial dissection step in the video?

• The ligaments of the elbow

• The ligaments of the knee

• The muscles of the forearm

• The relationship between the clavicle and scapula

Which ligament connects the humerus to the ulna?

• Radial collateral ligament

• Ulnar collateral ligament

• Annular ligament

• Patellar ligament

What is the function of the annular ligament?

• Connects the clavicle to the scapula

• Supports the knee joint

• Encircles the radial head

• Connects the humerus to the ulna

What happens when the ulnar collateral ligament is cut?

• The elbow joint becomes immobile

• The arm drops down

• The arm remains stable

• The radial head is exposed

What is revealed after cutting through the annular ligament?

• The humerus

• The radial head

• The scapula

• The olecranon process

Which part of the ulna is described as 'sticking out in the wind'?

• The annular ligament

• The ulnar collateral ligament

• The olecranon process

• The radial head

What is the significance of the proximal radio-ulnar joint?

• It is not essential for elbow function

• It allows the radius to float freely

• It enables pronation and supination

• It connects the humerus to the scapula

What movement is demonstrated by the radial head spinning on the humerus?

• Flexion

• Extension

• Abduction

• Pronation

What is the role of the radial head in the elbow joint?

• It connects directly to the clavicle

• It supports the knee joint

• It spins on both the humerus and ulna

• It is immobile

What is the overall impression of the elbow joint as described in the video?

• Rigid and inflexible

• Weak and unstable

• Complex and beautifully designed

• Simple and straightforward
