distal forelimb Flashcards
what is the carpus composed of
carpal bones
what is in the proximal row of the carpus
radial carpal bone
ulnar carpal bone
accessory carpal bone
what is in the distal row of the carpus
1st, 2nd, 3rd and 4th carpal bones
what are the 3 carpal joints
antebrachio-carpal = antebrachium and carpus
middle carpal = proximal and distal rows
carpo-metacarpal = distal row and metacarpal bones
which carpal joint provides most movement
antebrachio-carpal
what carpal joint provides least movement
carpo-metacarpal
what supports the carpal joints
collateral ligaments
function of the fibrocartilagenous reinforcement of the joint capsule
friction free surface for passage of tendons
passive maintenance of joint extension/ prevention of collapse into hyperextension
what is retinaculum
sleeve of deep fascia encloses the carpal region both at palmar and dorsal surface
forms carpal canal
where is the deep digital flexor tendon found
through the carpal canal
where is the superficial digital flexor tendon found
outside the carpal canal
palpation points of the carpal joint
accessory carpal bone
joint spaces
radius medial styloid process
lateral styloid process ulna
components of the manus
metacarpal bone
digit:
proximal phalanx
middle phalanx
distal phalanx
sesamoids
what is the 1st digit of the manus
dew claw
joints of the manus
metacarpo-phalangeal joint
proximal interphalangeal joint
distal interphalangeal joint
