Nerves & Vessels of the Lower Limb Flashcards
What are the rami that conform the lumbar plexus?
L1-L4
all the nerves of the lumbar plexus can be organised in regards to a muscle, this is.
Psoas Major
What Nerves come off the lateral border of psoas major in defending order?
Inguinal and Iliohypogastric Nerve (1)
Lateral Cutaneous Nerve of Thigh (2,3)
Femoral Nerve (2-4)
from the anterior surface of psoas muscle what nerve comes off?
Genitofemoral Nerve (1-2)
From the medial muscle of posts major comes what nerve?
Obturator Nerve (2-4)
what is the main function of the iliohypogastric nerve and the inguinal nerve?
Sensory supply to the skin of the inguinal canal and the scrotum
Motor to the lower fibres of the internal oblique and transversus abdominal
what supplies Lateral Cutaneous Nerve of Thigh and when can this cause pins and needles?
lateral surface of the thigh
pregnancy and ñoño
the genitofemoral nerve is 2 nerves in one sheath and their function is…
Genito Branch (spermatic cord and cremasteric muscle) Femoral Branch (area of the skin underneath the inguinal canal and scrotum)
what are the rami that conform the sacral plexus?
S1-4
with the lumbosacral trunk (L4-5)
what is the nerve of the anterior compartment of the thigh? what muscle does it NOT supply?
Femoral Nerve
Psoas Major
what is the sensory supply of the Femoral Nerve? distally via which branch?
all the antero-medial side of the lower limb (only medial side from one palm above ankle)
NO –> one palm above medial knee
From the knee down is via the Saphenous nerve
What are that main nerves that supply the anterior skin of the thigh?
Genitofemoral Nerve
Femoral Never
Lateral Cutaneous Nerve Of thigh
Obturator Nerve
What muscles are supplied by the obturator nerve?
how many division does it got?
Aductor longus
Adductor Brevis (2, 1Above)
Adductor Magnus
Gracilis
what are the relevant rami that make up the Sciatic Nerve?
L4,5
S1-3
What nerves are contained within the sheath of the Sciatic Nerve?
Tibial Nerve
Common Fibular Nerve
what nerve comes out in the gluteal region above piriformis and what does it supply?
Superior Gluteal nerve
For Gm and gm
what nerve comes out in the gluteal region bellow piriformis and what does it supply?
Inferior Gluteal Nerve (GM)
Sciatic Nerve
Posterior Cutaneous Nerve of Thigh (Hamstrings. X Short Head of Biceps)
what is in direct relationship (posteriorly) to the hip joint
Sciatic Nerve
Injured in A-P dislocations
what nerve supplies the short head of biceps?
Common Fibular Nerve
what is the main function of the tibial muscle?
Sensory supply?
all posterior muscles of the leg and the sole of the foot
Travels down sandwiched between superficial and deep muscles
[posterio-lateral leg {rural nerve} and sole of the foot {plantar and calcaneal nerves}]
in the foot the tibial nerve gives its terminal branches what is its trajectory?
from the medial side of the foot to the lateral side
Lateral and medial plantar nerves
where does the common fibular nerve gives off its branches and what are them?
At the levels of Fibularis Longus
Deep Fibular nerve
Superficial Fibular Nerve
The Deep Fibular nerve gives supply to
1 motor
2 sensory
1 Anterior Compartment, Extensor Digitorium Brevis
2 First toe cleft
The superficial Fibular nerve gives supply to
1 motor
2 sensory
1 Lateral Compartment , Fibularis longus and Brevis
2 lateral leg and dorm of foot
