T or F:
The third trochanter is only present in the horse.
True!
Which side of the tibia (lateral or medial) is the extensor groove on?
Lateral
On which side of the femur (lateral or medial) is the third trochanter located?
Lateral
Which nerve innervates the muscles located on the cranial aspect of the femur?
Femoral n.
Which nerve innervates the muscles located on the caudal aspect of the femur?
Sciatic n.
Which nerve innervates the muscles located on the cranial/dorsal aspect of the crus/pes?
Peroneal n.
Which nerve innervates the muscles located on the caudal/plantar aspect of the crus/pes
Tibial n.
Which nerve is responsible for the innervation of most of the adductors?
Obturator n.
Which nerve innervates the muscles located in the cranial pelvic region?
Cranial gluteal n.
Which nerve innervates the muscles located in the caudal pelvic region?
Caudal gluteal n.
Which muscles flex the hip?
Iliopsoas (Iliacus and psoas major)
Tensor fascia latae
Superficial gluteal
Rectus femoris
Pectineus
Which muscles extend the hip?
Middle gluteal
Biceps femoris (cranial and middle parts)
Gluteobiceps
Semitendinosus
Semimembranosus
Adductor
Quadratus femoris
Which muscles extend the stifle joint?
Tensor fascia latae
Quadriceps (vastus lateralis, intermedius, medialis, and rectus femoris)
Biceps femoris (cranial part)
Gluteobiceps
Which muscles flex the stifle joint?
Biceps femoris (middle part maybe)
Gluteobiceps
Semitendinosus
Semimembranosus
Gracilis (ox)
Which muscles are adductors of the pelvic limb?
Semimembranosus
Sartorius
Gracilis
Pectineus
Adductor
Quadratus femoris
External obturator
Which muscles are abductors of the pelvic limb?
Superficial gluteal
Middle gluteal
Deep gluteal
Biceps femoris (cranial part)
Gluteobiceps
Which muscles have actions on the pelvis? What is the action(s)?
Psoas minor flexes the pelvis or moves it laterally
Which muscles rotate the thigh laterally?
Iliopsoas (psoas major and iliacus)
Gemelli
Internal obturator
External obturator
Which muscles rotate the thigh medially?
Deep gluteal
Semitendinosus
Adductor
Middle gluteal (ox)
T or F:
Femoral nerve damage would result in the inability for a horse to extend the stifle and flex the hip.
Stifle extension would be impacted greatly but Pectineus (obturator), superficial gluteal (cranial/caudal gluteal nn), and iliopsoas (lumbar spinal nn. and femoral n) would still be able to contract allowing for hip flexion.
Which muscles does the femoral nerve innervate in the horse?
Psoas major
Iliacus
Quadriceps (all four heads)
T or F:
The greater ischiatic foramen is located cranial to the ischiatic spine.
True! The lesser is caudal to the acetabulum. Foramina are separated by the ischiatic spine.
T or F:
The fibula is on the medial aspect of the tibia.
False bitch! It is lateral!
Let's play horse or ox:

I have a more extensive vastus intermedius...
OX!
Damage to what muscle results in trochanteric bursitis in the horse?
Accessory head of middle gluteal muscle.
Which muscle is most affected in fibrotic myopathy?
Semitendinosus.
Caused by scar tissue and possible adhesions after injury.
Which muscles raise the femoropatellar joint capsule during extension?
Quadriceps femoris
T or F:
All muscles innervated by the obturator nerve adduct the limb in at least one of their actions.
True
T or F:
All adductors of the limb are innervated by the obturator nerve.
False! Sartorius is innervated by saphenous; semimembranosus and quadratus femoris are innervated by saphenous.
Which structures pass between the two heads of origin of sartorius in the ruminant?
Femoral a., v., and n.
T or F:
All muscles innervated by the femoral nerve extend the stifle in at least one of their actions.
False!
Iliacus and Psoas major have no action on the stifle!
Which muscles comprise the pelvic diaphragm?
Levator ani
Coccygeus
Which muscles are involved with rearing and kicking?
Biceps femoris
Middle gluteal
Which muscle fixes the anus during defecation?
Levator ani
Between which two structures is the trochanteric bursa located?
Greater trochanter and accessory head of middle gluteal
