Canine anatomy NUR AINSYAH NATASYA BINTI ABDUL AZIZ D10A027 (ye..saya la yang paling cute) Thoracic limb
Flexor=ms on the side of the limb towards which the joint bends • biceps brachii m. flexes the elbow. • Extensor=the ms on the opposite side. • triceps brachii m.=extensor of the elbow • Adductors-ms that tend to pull a limb toward the median plane • Abductors=ms that tend to move the limb away from the median plane • Agonists(prime movers)are ms directly responsible for producing the desired action. • The Antagonists are ms that oppose the desired actions. • Synergists are ms that oppose any undesired action of the agonists • Eg. in extension of the elbow, a movt. produced by the triceps brachii biceps(agonist for extension), brachii and brachialis are antagonists coz they produce the opposite action, flexion of the elbow.
extensor carpi radialis m. (1) • common digital extensor m. (2) • lateral digital extensor m. (3). • ulnaris lateralis m. (4) • Two minor muscles are the • brachioradialis m. (5) • abductor pollicis longus m. (6). • Fascia has been removed except for the extensor retinaculum (7) that binds digital extensor tendons at the carpus. (Scissors elevate branches of the common digital extensor tendon.)
common digital extensor m. (1) • lateral digital extensor m.(2) • (tendon are elevated by forceps) • extensor carpi radialis m. (3) • ulnaris lateralis m. (4) • Craniolateral antebrachial muscles originate form the vicinity of the lateral epicondyle of the humerus (asterisk). • anconeus m. (5), caudal to the epicondyle.
medial epicondyle of the humerus (asterisk). deep fascia has been removed from the antebrachium except for flexor retinaculum(1), which binds digital flexor tendons in the carpus. superficial digital flexor m. (2) and its tendon branches are elevated by instruments. flexor carpi ulnaris m. (arrows).
superficial digital flexor m. (1)have been reflected. • flexor carpi ulnaris m.(2) has humeral and ulnar heads. Latter elevated by the forceps. • flexor carpi radialis m. (3) is medially on the limb. • deep digital flexor m. (4) it’s tendons are visible distal to the flexor retinaculum (5).
deep digital flexor m (1)it’s humeral head is being pulled by forceps. small radial head (2) attaches to the radius. The ulnar head (3) originates from the ulna. deep layer of flexor retinaculum (asterisk) has been cut to release the tendon (arrow) of the deep digital flexor m. • superficial digital flexor m. (4); • flexor carpi ulnaris m. (5); • flexor carpi radialis m. (6); • and pronator teres m. (7).
Lab 5 - Image 5 The largest of the hamstring (caudal thigh) muscles is the biceps femoris m. (1) which originates from the ischium and inserts broadly on fascia lata (2) and crural fascia (3). The muscle has been transected in two locations to facilitate reflecting it. The semitendinosus m. (4) is partially exposed. Other visible (non-hamstring) muscles include: sartorius m. (5), tensor fasciae latae m. (6), middle gluteal m. (7), superficial gluteal m. (8), levatorani m. (9), and external anal sphincter m.(10).
