Equine Forelimb Lecture Flashcards
T/F Horses and pigs have acromion process
F
Lack acromion process
Lesser tubercle insertion for
supraspinatus m and subscapularis m
Intertubercular groove has what pass through it
Biceps brachii
Accessory carpal articulates with what ONLY
Caudal surface of ulnar carpal and ulna
How many distal carpal bones are in the horse?
3
Give proximal set of carpal bones from medal to lateral
Radial carpal, intermediate carpal, ulnar carpal
T/F Lateral splint bone in horse is usually the longest
F
Medial splint
Proximal sesamoids are located palmar or cranial
Palmar
Fetlock joint
Between MC and first phalanx
Give equine phalanges from cranial to palmar
Long pastern bone AKA P1 AKA proximal phalanx
Short pastern bone AKA P2 AKA Middle phalanx
Coffin bone AKA P3 AKA Distal phalanx
Distal sesamoid on horse
Navicular bone
Articulates on caudal surface of coffin bone and distal surface of P2
What joints communicate in forelimb
Middle carpal and carpometacarpal
Give joints from cranial to rostral after MC
Fetlock jt AKA metacarpophalangeal jt
Pastern jt AKA proximal interphalangeal jt (PIP)
Coffin jt AKA distal interphalangeal jt (DIP)
Greater tubercke of humerus is divided into
Cranial and caudal parts
Intertubercular groove is divided by
Intermediate tubercle
What bones are fused together?
Radius and ulna
Insertion of biceps brachii
Radial tuberosity
What is single functional digit in horse
Digit 3
Where can infection accumulate on dorsal/thoracic region of horse
Near dorsal scapular ligament
Main blood supply to distal limb
Median a
Median a continues as what? What is major a on lateral side?
Median palmar a
No major a on lateral side of MC
Where does medial palmar a divide?
Above fetlock into medial and lateral palmar dgital a
Suprascapular n innervates
Supraspinatus and infraspinatus
What n supplies most of structures below carpus?
Median and ulnar n
Where does medan n split
Above carpus into medial and lateral palmar n
Ulnar n supplies
Palmar branch to lateral palmar n above carpus
Lateral palmar n supplies
Deep branch to suspensory ligament just below accessory carpal bone
Medial and lateral palmar n becomes
Medial and lateral palmar digital n as they cross fetlock
What innervates hoof capsule and contents?
Medial and lateral palmar digital n
