degree of fusion =
how developed the muscles are
supinators of the forearm
supinator and brachioradial
dogs have what degree of supination
50

over 100
pronators of forearm
pronator teres and pronator quadratus
What muscle is not always constant
brachioradial
brachioradial origin
proximal part of the crest of lateral epicondyle
brachioradial insertion
distal radius, proximal 1/4
brachioradial action
supination of antebrachium
brachioradial innervation
radial nerve
supinator shape
short, broad, flat, oblique
supinator origin
lateral epicondyle of humerus
supinator insertion
cranial aspect of proximal radius
supinator action
supination of antebrachium, elbow flexion
supinator innervation
radial nerve
pronator teres is found in between
Extensor carpi radialis and Flexor carpi radialis
pronator teres origin
medial epicondyle of humerus
pronator teres insertion
medial border of radius between proximal and middle thirds
pronator teres action
pronation, flex elbow
pronator teres innervation
median nerve
pronator teres shape
rounded proximally, flat distally
pronator quadratus fills in space between:
radius and ulna
pronator quadratus fibers run:
transversely between ulna and radius
pronator quadratus origin and insertion
SAME: apposed surfaces of the radius and ulna
pronator quadratus action
pronate paw
pronator quadratus innervation
median nerve
extensors of carpus located
cranio dorso lateral side
flexors of carpus located
caudal palmar side
extensors of carpus arise from:
lateral epicondyle of humerus
flexors of carpus arise from:
medial epicondyle of humerus
extensor carpi radialis origin
lateral supracondylar crest
extensor carpi radialis insertion
tuberosities on dorsal aspect of proximal metacarpals II and III
extensor carpi radialis action
extension of carpus
extensor carpi radialis innervation
radial nerve
extensor carpi ulnaris origin
lateral epicondyle of humerus
extensor carpi ulnaris insertion
lateral aspect of proximal metacarpal V and accessory carpal bone
extensor carpi ulnaris action
extension of carpus, abduction of carpus
extensor carpi ulnaris innervation
radial nerve
flexor carpi ulnaris heads
ulnar and humeral
extensor carpi radialis held in place by
extensor retinaculum
flexor carpi ulnaris ulnar head origin
caudomedial aspect of olecranon
flexor carpi ulnaris insertion
accessory carpal bone
flexor carpi ulnaris action
flexion of carpus
flexor carpi ulnaris innervation
ulnar nerve
flexor carpi ulnaris humeral head origin
medial epicondyle of humerus
flexor carpi radialis passes through
carpal canal
carpal canal is created by
