What nerve innervates the adductor longus?
What nerve innervates the adductor longus?
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.
Does adductor magnus have dual nerve supply?
Nerve supply It is a composite muscle as the adductor and hamstring portions of the muscle are innervated by two different nerves. The adductor portion is innervated by the posterior division of the obturator nerve while the hamstring portion is innervated by the sciatic nerve.
What Innervates the adductor brevis?
Innervation. The adductor brevis is innervated dually by the anterior and posterior branches of the obturator nerve.
What nerve is responsible for thigh adduction?
The obturator nerve (L2–L4) supplies the pectineus; adductor (longus, brevis, and magnus); gracilis; and external obturator muscles. This nerve controls adduction and rotation of the thigh. A small cutaneous zone on the internal thigh is supplied by sensory fibers.
What causes pain in the adductor longus muscle?
Adductor strain is a common cause of groin injury and pain among athletes. Risk factors include previous hip or groin injury, age, weak adductors, muscle fatigue, decreased range of motion, and inadequate stretching of the adductor muscle complex.
What spinal nerves affect the thighs?
Sciatic Nerve Anatomy
- The sciatic nerve is formed in the lower spine by the combination of motor and sensory fibers from spinal nerves L4 to S3.
- This long, thick, and bulky nerve runs along the back of the thigh and leg and terminates in the foot.
- The nerve supplies most areas of the thigh, leg, and foot.
What is the function of the adductor longus muscle?
Its main actions is to adduct and laterally rotate the thigh; it can also produce some degree of flexion/anteversion. As part of the medial compartment of the thigh, the adductor longus is innervated by the anterior division (sometimes the posterior division) of the obturator nerve.
Where is the nerve supply of the adductor magnus?
This can be achieved by a saphenous nerve block at the level of the adductor canal. The nerve supply of the adductor magnus muscle is reflected by its position in both the medial and the posterior compartment. Like other muscles of the medial compartment, the adductor part is innervated by the posterior division of the obturator nerve (L2, L4).
Where are the adductor longus and gracilis located?
Innervation. All three adductors (except the hamstring part of the adductor magnus) and gracilis are supplied by the obturator nerve (anterior divisions of the ventral rami of L2-L4). The obturator nerve is a branch of the lumbar plexus, and descends medial to the psoas major muscle in order to enter the pelvis.
Is the adductor part of the medial compartment innervated?
The nerve supply of the adductor magnus muscle is reflected by its position in both the medial and the posterior compartment. Like other muscles of the medial compartment, the adductor part is innervated by the posterior division of the obturator nerve (L2, L4).
