Nerve info Flashcards
Location of femoral nerve
Within femoral triangle
Outside femoral sheath
Lateral to femoral Artery
obturator nerve pierces what ? straddles what
Obturator membrane to serve medial compartment of thigh
Straddles adductor brevis
*superior and medial cluneal nerve associated with?
Dorsal rami of spinal nerves
inferior cluneal is branch of
posterior femoral cutaneous nerve
*inferior cluneal nerve is associated with?
Ventral rami of sacral plexus
Where do the superior gluteal artery and nerve exit?
Above piriformis
Where do inferior gluteal artery and nerve exit
Below, on inferior border of piriformis
Is the piriformis superficial or deep to sciatic? What about the rest of the lateral rotators
Piriformis is superficial to sciatic, the rest are deep
What do the pudental nerve and artery cross
Greater foramen and lesser foramen to reach the genitalia
Location of superficial gluteal nerve with respect to gluteus medius and minimus
Deep to medius
Superficial to minimus ( like a sandwich )
Sciatic splits into
Tibial (medial)
Common peronal (lateral) ( synonymous with fibular n )
Branch – sural →-runs with lesser saphenous v
Where does the posterior femoral cutaneous nerve emerge
To the inferior border of gluteus maximus
Does the saphenous nerve go into popliteal fossa
NO
tibial nerve roots
L4-s3
How does the tibial nerve descend?
THROUGH the popliteal fossa
Location of tibial nerve with respect to muscles
Superficial to popliteus and deep to gastrocnemius and soleus
Where does the tibial nerve go in ankle
Behind medial malleolus
Trajectory of common peronneal nerve in knee area
Does NOT go through interosseous membrane
Wraps around head of fibula laterally and branches off
Superficial peroneal - to lateral muscles of leg
Deep common peroneal- to anterior muscles of leg
Cutaneous innervation superficial peroneal nerve
Dorsum of foot
Cutaneous innervation for deep peroneal nerve (autonomous zone)
First webbed space – between big toe and other one
Cutaneous innervation for sural nerve
lateral dorsal cutaneous nerve
Achilles reflex tests for?
Tibial nerve
Ventral rami of S1
