Lecture 13: Carnivoran Manus and Paw Flashcards
the digital pad is thick in dogs and ___ in cats
thin
what are the annular ligaments
ligaments that protect the synovial sheath that covers the tendons of the digital flexors and prevent tendons from ‘bowing’ when forepaw flexed
protrusion of claws occurs from contraction of what muscles
flexor digitorum profundus
what ligaments keep the claws elevated
they extend from the proximal ends of middle phalanges to the unguicular crest of distal phalanges
dorsal elastic ligaments
how do the dorsal elastic ligaments differ in cats
differ in length and attachments
length
- medial DE is longer while lateral DE is short
attachment
- distal phalanx is oriented obliquely to the middle phalanx
what is an onychectomy
declawing / amputation of distal phalanx and claw
what arteries anastomose in the manus
dorsal and palmar arteries
what muscles does the ulnar nerve innervate
muscles of digit V
lumbricals
interosseous muscles
what muscles does the median nerve innerave
muscles moving digit I
what is the muscles shown in red
interflexorious
what muscle is shown in bright green
abductor digit V
what muscle is shown in hot pink
lumbricals
what muscle is shown in yellow
flexor of digit I
what muscle is in dark green
adductor digit I
what muscle is gray
adductor digit II
what muscle is purple
flexor digitorum brevis
what muscle is shown in light blue
abductor digit I brevis
what muscle is in fuschia
adductor digit V
what muscle is dark blue
flexor digit I brevis
