saphenous n.
What nerve provides motor to sartorius?
saphenous n.
What does the obturator nerve supply?
motor to external obturator, pectineus, gracilis, and adductor
What does the caudal gluteal nerve supply?
superficial gluteal, vertebral heads of biceps femoris, semitendinosus and semimembranosus
What does the cranial gluteal nerve supply?
gluteal muscles and tensor fascia latae
What are the divisions of the sciatic nerve?
tibial and common peroneal

Damage to the cranial or caudal portion of the reciprocal apparatus results in poor prognosis?
caudal
What makes up the reciprocal apparatus?
cranial- peroneus tertius
caudal- SDF and gastroc fibrous band
The reciprocal apparatus results in opposing actins of the hock and stifle. True or false?
False- when one flexes or extends, so does the other

False- There are proximal and distal check ligaments in the forelimb.
In the hindlimb, there are only accessory ligaments of the DDF.
What acts as the proximal check ligament in the rear limb of the horse?
Attachment of the SDF to the tuber calcanei
