nerve groupings - exam 3 Flashcards
anterior thigh muscles
- pectineus
- sartorius
anterior thigh muscle innervations?
pectineus and sartorius:
femoral nerve L2-L3
pectineus: may receive a branch from obturator nerve
list the glute muscles
- glute maximus
- glute medius
- glute minimis
- tensor fascia latae
glute muscle nerve innervations
glute maximus: inferior gluteal nerve L5,S1,S2
glute med,min, TFL: superior gluteal nerve L4,L5,S1
list the deep gluteal muscles
- piriformis
- obturator internus
- sup gemelli
- inferior gemelli
- quadratus femoris
list the deep gluteal nerve innervations + spinal levels
piriformis: branches of anterior rami S1 + S2
obturator internus & superior gemelli: nerve to obturator internus L5,S1
inferior gemelli & quadratus femoris: nerve to quadratus femoris L5,S1
list the medial thigh [adductors]
- adductor brevis
- adductor longus

- gracilis
- obturator externus
innervation of adductors [medial thigh]
- adductor brev, long, magnus [add. part]: obturator nerve L2,L3,L4
- gracilis: obturator nerve: L2,L3
- obturator externus: L3,L4
- adductor hamstrings: tibial division of sciatic nerve L4

- tibialis anterior: deep fibular nerve L4,L5
- fibularis tertius, ext hallucis + digitorum longus: deep fibular nerve L5,S1
posterior lower leg - superficial muscles
- gastrocnemius
- soleus
- plantaris
posterior lower leg - superficial muscles nerve innervations
[gastrocnemius, soleus, plantaris] tibial nerve S1,S2
