Terms
undefined, object
copy deck
- how pigment is produced in the hoof
- malanocytes produce melanin near epidermal germ layer covering coronary dermal papilla
- cartiliage of distal phalanx
- medial/lateral ungual cartilages
- Circulation
- The medial/lateral palmar digital arteries and viens, connected by the terminal arch.
- blood supply to coronary band
- coronary circumclex artery(proximal) and terminal arch (distal) have small branches meeting at the coronary band to form the coronary venous plexus
- terminal arch
- blood supply/return of circumflex artery of the sole, lamenar arteries, and distal aspect of coronary band
- ligaments of the navicular bone
- navicular suspensory ligament, attatches along proximal border of distal sesamoid. distal navicuar ligament (impar) (interosseous) attatches distal flexor aspect of DS to proxiomal palmar aspect of P3
- tendons of the foot
- deep digital flexor tendon inserts at distal palmar aspect of P3; common difital extensor tendon inserts at the extensor process of P1
- suspensory ligament
-
origin: proximal third metacarpal
insertion: proximal sesamoid bones
splits at sesamoids to form extesor processes, wraping around fetlock to join common digital extensor - superficial digital flexor
-
origin: medial epicondyle of humerus
insertion: distal P1 and proximal P2 - deep digital flexor
-
origin: humerus, radius, ulna
insertion: palmar aspcect P3 - common digital extensor
-
origin: lateral epicondyle of humerus
insertion: dorsal P2 and extensor process of dorsal P3 - order of bones top down
- scapula, humerus, ulna, radius, carpal
- sesamoidian ligaments
-
oblique: origin: distal aspect of the proximal sesamoids; insertion: proximal P1
straight (superficial): origin: distal aspect of the proximal sesamoids; insertion: proximal P2 - tip of ulna
- olecranon
- scapula need to know
- spine of scapula houses infraspinatious nerve=sweeny disease when parylized
