Upper Limb Flashcards
consist of the bones of the arm, forearm, wrist and hand
Upper Limb
•Region between the shoulder and the elbow.
•It contains the humerus.
Arm (Brachial)
connecting the upper arm to the forearm. It is classed as a hinge-type synovial joint which allows flexion and extension
Elbow Joint
- Consist of two bones: the ulna (medial side) and radius (lateral side)
- The ulna acts as the stabilising bone, with the radius pivoting to produce movement.
Forearm (Antebrachial)
Slightly longer than the radius. It has the main responsibility for forming the elbow joint with the humerus.
Ulna
Thin at its proximal end and wide
Radius
located near the elbow. It is articulation between the head of the radius and the radial notch of the ulna.
Proximal Radioulnar Joint (Superior)
located near the wrist. It is an articulation between the ulnar notch of the radius and the ulnar head.
Distal Radioulnar Joint (Inferior)
•Both of these joints are classified as pivot joints, responsible for pronation and supination of the forearm.
Proximal and Distal Radioulnar Joint
- A short region between the forearm and the hand.
- Consist of 8 irregular bones arranged in two rows of four bones each and form a light curvature (carpal tunnel)
Wrist (Carpal)
Proximal Row of Carpal Bones
Scaphoid, Lunate, Triquetrum, Pisiform
Distal Row of Carpal Bones
Trapezium, Trapezoid, Capitate, Hamate
•The skeleton of the hand includes the Palm (Metacarpals) and Fingers (Phalanges)
•They are numbered 1 to 5 from the thumb (lateral side) to the little finger (medial side)
Hand
Attach to the carpal and forms the bony framework of the hand. The ends or heads of the five _______ forms the knuckles.
Metacarpals
Each finger is composed of three small bone named as proximal, middle, and distal phalnx according to their position. The thumb has two _______, proximal and distal.
Phalanges
