What does the femoral n. innervate?
|
Iliopsoas, quadriceps femoris mm.
|
|
What does the saphenous n. innervate?
|
sartorius m. (usually)
|
|
Which nerves provide cutaneous innervation to the following areas? (medial view in case you couldn't tell)
|
A - Genitofemoral n.
B - Caudal cutaneous femoral n. C - Saphenous n. D - Caudal cutaneous sural n. E - Cutaneous brs. of superficial peroneal n. |
|
How would dysfunction of the femoral nerve present?
|
Inability to extend stifle or support weight, reduced ability to rotate thigh inward, and loss of sensation over the medial stifle region.
|
|
From which spinal nerves does the obturator nerve arise?
|
L4 - L6
|
|
Which muscles does the obturator nerve innervate?
|
External obturator and adductors of the pelvis (adductor, pectineus, and gracilis) mm.
|
|
T or F:
Dysfunction of the obturator nerve would result in loss of sensation to the inguinal region and inability to adduct the hip and thigh. |
False, *******!
Obturator has no cutaneous innervation! Try and get it right next time... |
|
OK here is an easy one - through which foramen does the obturator n. pass?
|
Obturator foramen
|
|
From which spinal nerves does the caudal cutaneous femoral nerve arise?
|
Ventral brs. of S1 and S2 (+/- S3)
|
|
Which spinal nerves give rise to the lumbosacral trunk? Which nerves does this trunk give rise to?
|
Ventral brs. of L6, L7, and S1 (+/- S2).
Gives rise to Cranial gluteal, caudal gluteal, and sciatic nn. |
|
Which muscles does the cranial gluteal nerve innervate?
|
Middle gluteal, piriformis, deep gluteal, and tensor fascia latae mm.
|
|
Which region depicts the cutaneous area of the cranial gluteal nerve? How 'bout the caudal cutaneous femoral n.?
|
*******! The cranial gluteal nerve has NO cutaneous area! Hopefully you got that D is the region for the caudal cutaneous femoral n.!!
|
|
ID these nerves of the rump (lateral view).
|
A - Sciatic n.
B - Caudal gluteal n. C - Lumbosacral trunk D - Cranial gluteal n. |
|
Which muscles does the caudal gluteal nerve innervate?
|
Superficial gluteal m.
|
|
Which muscles does the sciatic nerve innervate within the pelvis?
|
Internal obturator
Gemelli Quadratus femoris mm. |
|
Which muscles does the sciatic nerve innervate caudal to the hip?
|
Biceps femoris
Semimembranosus Semitendinosus mm. |
|
Which nerves course over the greater ischiatic notch?
|
Nerves of the lumbosacral trunk
(Sciatic, caudal and cranial gluteal nn.) |
|
ID these nerves
|
A - Sciatic n.
B - Tibial n. C - Peroneal n. |
|
What spinal nerves give rise to the sciatic n.? The common peroneal n.? The tibial n.?
|
Sciatic - L6, L7 & S1 (+/- S2)
Peroneal - L6/7 Tibial - L7 & S1 |
|
What does the tibial nerve provide motor innervation to?
|
extensors of the hock and flexors of the digits
|
|
Which muscles does the tibial nerve innervate?
|
Gastrocnemius m.
Superficial digital flexor m. Popliteus m. Deep Digital flexor m. Caudal tibial m. |
|
Which nerves generate the following autonomous zones?
|
A - Genitofemoral n.
B - Saphenous C - Peroneal D - Tibial E - Sciatic F - Caudal cutaneous femoral G - Lateral cutaneous femoral |
