week 6 Flashcards
what are the attachments of the extensor carpi radialis m. of horse and ruminants
originates from the lateral supracondylar crest and radial fossa of the humerus and deep antebrachial fascia; inserts on the metacarpal tuberosity on the proximal aspect of metacarpal III
what is the action of the extensor carpi radialis
extends and fixes the carpus and flexes the elbow
extensor carpi obliquus m. attachments of horse
originates from the middle of the radius, courses over the tendon of extensor carpi radialis and through the medial groove on the distal radius, and then inserts proximally on metacarpal II
extensor carpi obliquus m. action
extends the carpus
common digital extensor muscle and tendon attachments
arises from the lateral epicondyle of the humerus, lateral border of the radius, lateral collateral ligament of elbow, lateral surface of the ulna, and antebrachial fascia; insert on the extensor process of teh distal phalanx, proximodorsally on the middle phalanx, and on the proximal phalanx with the tendon of the lateral digital extensor
what is the action of the common digital extensor muscle and tendon
extends the carpus and digit and flexes the elbow
what are the attachments of the ulnaris lateralis muscle of the horse
lateral epicondyle of the humerus and two tendons of insertion on accessory carpal bone and metacarpal 4 (splint bone)
what is the function of the ulnaris lateralis
flexes the carpus and extends the elbow
flexor carpi ulnaris attachment of ulnar head in the horse and ruminants
medial aspect of the olecranon
flexor carpi ulnaris attachment of humeral head in the horse and ruminants
from the medial epicondyle of the humerus
insertion of flexor carpi ulnaris m. in the horse and ruminants
accessory carpal bone
what is the action of the flexor carpi ulnaris
flexes the carpus and extends the elbow
what are the attachments of the flexor carpi radialis in the horse
the medial epicondyle of the humerus and inserts on the proximal end of metacarpal II
What is the function of the flexor carpi radius
flexes the carpus and extends the elbow
what are the attachments of the superficial digital flexor
arises from the medial epicondyle of the humerus and inserts on the proximal an dmiddle phalanges
flexor manica
sleeve formed by the superficial digital flexor around the deep digital flexor tendon at the level of the metacarpophalangeal joint
deep digital flexor muscle humeral head of horse
largest and arises from the medial epicondyle of the humerus
deep digital flexor m. ulnar head of horse
arises from the olecranon medially
deep digital flexor radial head of horse
middle of the radius and extends caudally
deep digital flexor m. inserts on
flexor surface of the distal phalanges
deep digital flexor action
extends the elbow joint, flexes the carpus and flexes the digit
extensor carpi obliquus attachments in ruminants
originates on the lateral surface of the distal half of the radius, the craniolateral edge of the ulna, and the interosseous ligament; inserts on metacarpal III/IV
what is the function of the extensor carpi obliquus
extends the carpus
what are attachments of the ulnaris lateralis in the ruminant
lateral epicondyle of the humerus and two tendons of insertion on accessory carpal bone and metacarpal IV and/or V.
what is the function of the ulnaris lateralis
flexes the carpus and extends the elbow
flexor carpi radialis attachments in the ruminant
medial epicondyle of the humerus and inserts on the proximal end of metacarpal III/IV
what is the function of the pronator teres in ruminants
assists with flexion of the elbow (in adults, too fibrous to have any function)
what courses through the palmar carpa canal in the ruminant
deep part of the suprficial digital flexor tendon, deep digital flexor tendon, median artery, median vein, median nerve, and palmar branch of the ulnar nerve
superficial digital flexor muscle attachments in the ruminant
medial epicondyle of the humerus and inserts on the middle phalanges of digits 3 and 4
superficial part of superficial digital flexor tendon courses
within the flexor retinaculum and superficial to the carpal canal
deep part of the superficial digital flexor muslce course
through the carpal canal
what is the action of the superficial digital flexor m.
flexes the metacarpophalangeal joints, proximal interphalangeal joints and carpus, and extends the elbow

where does the deep digital flexor in ruminants insert
on distal phalanx of digits 3 and 4
deeep digital flexor m. action
flexes the digits and the carpus and extends the elbow
interosseous m. attachments in the ruminant
proximocaudal aspect of metacarpals III and IV and distal row of carpal bones; insertion on the proximal sesamoids
