Forelimb Joints Flashcards
Shoulder Joint movement (5)
-flexion
-extension
-some rotation
-abduction
-adduction
The shoulder joint is a
Simple, ball and socket joint
Enarthrosis means
Ball and Socket Joint
The joint capsule of the shoulder joint is (2)
-simple and loose to allow for a large range of movement
-provides padding and lubrication for the Biceps brachii origin
Ligaments of the shoulder joint includes:
-Gleno-humeral Ligaments
-Transverse Humeral Retinaculum
The Gleno-humeral Ligament is:
-shoulder joint ligament
-lateral and medial
Elbow Joint movement (3)
-flexion
-extension
-rotation (supination/pronation)
The elbow joint is a
compound joint (ie. 3 in 1)
The elbow joint is comprised of
-humero-radial joint
-humero-ulnar joint
-radio-ulnar joint
The joint capsule of the elbow joint is
-tight
-separated into an Extensor Pouch Caudally and Flexor Pouch Cranially
4 ligaments of the elbow joint
-Collateral Ligaments (lateral and medial)
-Annualar Ligament
-Oblique Ligament
-Olecranon Ligament
The Annular Ligament is: (2)
-a ligament of the elbow joint
-holds the head of radius on top of the ulna
The Oblique Ligament is: (3)
-a small band of fibres on the cranial aspect of the elbow
-loose except during extension
-prevents over-extension
The Olecranon Ligament is: (3)
-small
-on the caudal aspect of elbow
-loose except during flexion
Carpal joint movement (2)
-flexion
-extension
3 parts to the Carpal Joint
-Antebrachiocarpal joint (most movement)
-Intercarpal joint
-Carpometacarpal joint (least amount of movement)
The Flexor Retinaculum
is an outer sleeve that holds the deep and superficial digital flexors in place
4 ligaments of the Carpal Joint
-Dorsal Carpal Ligament
-Palmar Carpal Fibrocartilage
-Collaterals (lateral and medial
-Interosseous
Intermetacarpal Joint movement
Gliding
Ligament of the Intermetacarpal Joint
Interosseous Metacarpal Ligaments
Metacarpophalangeal & Phalangeal joint movement
-flexion
-extension
The joint capsule of the metacarpophalangeal and phalangeal joints is
simple
Ligaments of the metacarpophalangeal and phalangeal joints are
-Collaterals (lateral and medial)
-dorsal elastic ligament
Ligaments of the Palmar Sesamoid Bones
-Lateral and Median Sesamoidean
-Intersesamoidean
-Distal Sesamoidean
-Cruciate Ligaments
The Retinacula
holds the flexor tendons close to the palmar surface of the manus (ie. holds superficial and deep digital flexors in place)
Three parts of the Retinacula
-proximal
-middle
-distal
