Upper Extremity

Question 1

Maintains the alignment of associated joint structures and limits hyper extension of the wrist.
Originates interior surface of radius in attaches to capitate, triquetrium and scaphoid

Answer 1

Palmar radiocarpal ligament.

Question 2

This ligament limits owner deviation and becomes taught when the rest it is in extreme extension and flexion. Originates from styloid process of radius and inserts on the scaphoid and trapezium

Answer 2

Radial collateral ligament

Question 3

This is located close to the deep surface of the flexor retinaculum. The median nerve enters the palm through here. Tenosynovitis, inflammation of the flexor retinaculum may result in compression.

Answer 3

Carpal tunnel

Question 4

Thence band of fibrous connective tissue that runs obliquely from the radius to the owner serves as a stabilizer against axial forces to wrist.

Answer 4

Interosseous membrane

Question 5

This ligament extends from the lateral at the condyle of humerus to the lateral border of olecranon process of ulna and annular ligament. Prevents adduction of elbow joint and reinforcement radio humeral articulation.

Answer 5

Radial collateral ligament

Question 6

Runs from medial epicondyle of humerus to proximal portion of ulna. Prevents excessive abduction.

Answer 6

Ulnar collateral ligament

Question 7

Consists of a band of fibers that surrounds the head of the radius. Allows radius had to rotate and retain contact with radial notch of ulna.

Answer 7

Annular ligament.

Question 8

Is capsular in nature and function this ligament stretches for radio collateral in attaches above upper edge of coronoid fossa extending to the low coronoid process

Answer 8

Anterior ligament.

Question 9

The only major ligament on the dorsal surface of the wrist. Limits wrist flexion.
Originates posterior surface of distal radius in styloid process and attaches to the lunate and triquetrium

Answer 9

Dorsal radiocarpal ligament
