What does the obturator innervate?
Local Anatomy The anterior branch of the obturator nerve innervates the adductor longus, adductor brevis, and gracilis muscles, as well as giving innervation to the hip joint. The obturator nerve originates from posterior divisions of L2, L3, and L4 spinal roots.
Which nerve Innervates the adductor muscles?
obturator nerve
Like other muscles of the medial compartment, the adductor part is innervated by the posterior division of the obturator nerve (L2, L4).
What nerve innervates the quadriceps muscle?
The femoral nerve innervates the sartorius, pectineus, and quadriceps femoris, and iliacus muscle of the iliopsoas. It receives nerve supply by the nerve roots L2 through L4, innervating both the hip flexor and quadriceps muscle groups.
What nerve Innervates the piriformis?
The majority of piriformis muscles are innervated by the superior gluteal nerve. Clin Anat.
What nerve innervates the hamstrings?
sciatic nerve
The hamstring muscle complex is innervated by nerves that arise from the lumbar and sacral plexuses. These plexuses give rise to the sciatic nerve (L3-S4), which bifurcates into the tibial and common peroneal (fibular) nerves at the level of the tibiofemoral joint.
What is innervated by the femoral nerve?
The motor branches of the femoral nerve are the nerve to pectineus, nerve to sartorius and muscular branches to the quadriceps femoris. They innervate the flexors of the hip (pectineus, iliacus, sartorius) and the extensors of the knee (quadriceps femoris).
What does saphenous nerve innervate?
Anatomy. The saphenous nerve is the largest branch of the femoral nerve and innervates the medial portion of the lower leg and the foot. The nerve travels with the femoral artery through Hunter’s canal, and at the medial condyle of the distal femur it supplies the medial portion of the knee and the lower leg.
What is the sciatic nerve composed of?
The sciatic nerve is composed of two distinct trunks, the medial or tibial division and the lateral or fibular division. The tibial division (medial part) innervates all the hamstring muscles with the exception of the short head of the biceps femoris which is innervated by the lateral division (fibular).
