Bones
Describe sesamoid bones, both dorsal and palmar
Dorsal sesamoid bones: one sesamoid bone in the metacarpophalangeal joint on digits II-V
Palmar sesamoid bones: One sesamoid bone in the Metacarpophalangeal joint on digit I and a pair of sesamoid bones in the metacarpophalangeal joint on digits II-V
Dorsal/elastic ligament on the dorsal aspect - retraction
Deep digital flexor tendon on the palmar aspect - protraction
Artery that supplies the dorsal aspect
Radial artery
Layman's terms for the phalanges
Proximal phalanx - Long pastern bone
Middle phalanx - Short pastern bone
Distal phalanx - Coffin bone
Name of digits
Digits III-IV
Names of phalanges of the digits
Digit I: Proximal and distal phalanges
Digits II-V: Proximal, middle, and distal phalanges
Tendons that insert on the extensor processes of digits II-V
Digit II: Common digital extensor
Digits III-V: Common digital extensor and lateral digital extensor
Artery that supplies the palmar aspect
Ulnar artery, median artery, superficial palmar arch artery
Insertion of the common digital extensor tendon
Parietal surface with extensor process
Seasmoid bone names, number, and locations
Proximal sesamoid bones (pair) - digits III-IV palmar aspect in metacarpophalangeal joint
Distal sesamoid bones (pair) - digits III-IV palmar aspect of distal interphalangeal joint
Insertion point of the Common Digital Extensor and the Lateral Digital Extensor, and it's location
Extensor process - Dorsal distal phalanx
Origin and insertion for the deep digital flexor tendon and the superficial digital flexor tendon, ligaments that they pass through, and their actions
DDF: medial epicondyle - flexor tubercle on palmar aspect of digits I-V - passes through the proximal and distal annular ligaments - flexes carpal and digital joints
SDF: medial epicondyle - palmar base of middle phalanx of digits II-V - passes through the palmar annular ligament - flexes carpal and proximal digital joints
Digit I is an autonomous region
Radial nerve
Ligaments that hold down the superficial digital flexor tendon and the deep digital flexor tendon
Proximal annular ligament - SFD and DDF tendon
Distal annular ligament - DDF tendon
Dewclaws
Digits II and V which have only the distal phalanx
Flexor tubercle location and is insertion for which muscle tendon
Palmar distal phalanges of digits I-V
Insertion for deep digital flexor muscle tendon
Ligaments and tendons associated with the flexor manica
Ligaments: Palmar annular ligament
Tendons: Deep digital flexor tendon and superficial digital flexor tendon (surrounded by the digital synovial sheath)
Autonomous area for Ulnar nerve
Digit V and lateral surface of the metacarpus
Navicular bone and bursa
Navicular bone is the distal sesamoid bone on the palmar surface
Navicular bursa is the synovial sac between the distal sesamoid bone and the DDF tendon
Most distal anatomical feature of the thoracic limb
Regions of the outer hoof, Anatomy of hoof from superficial to deep, Anatomy of the corium from proximal to distal
Regions: Toe, quarter, heel
Anatomy superficial to deep: hoof wall, white line, bars, sole, paracuneal groove, frog
Anatomy of corium (proximal to distal): perioplic corium, coronary corium, laminar corium (dermis lamina interconnects with the epithelial lamina of the hoof capsule)
