On the craniolateral leg,
Give the origin, insertion, innervation and action of the Cranial Tibial muscle.
ORIGIN- extensor groove and the adjacent articular margin of the tibia; the lateral edge of the cranial tibial border
INSERTION - The plantar surface of the base of metatarsals I and II.
INNERVATION - Fibular nerve
ACTION - Flexes hock, rotates paw laterally
Caudal Thigh
Origin: Ischiatic tuberosity
Insertion: Patella, tibial crest, tuber calcanei
Primary Action: Extends hip, stifle, and hock; flexes stifle (caudal part)
Innervation: Sciatic nerve
Which muscle is this?
