2023年11月3日 · It is a mixed nerve which arises from the ventral (anterior) rami of the spinal nerves L2-L4. The function of the obturator nerve is to provide motor innervation to all the medial muscles of the thigh (hip adductors) except for the ischiocondylar (hamstring) part of …

2023年10月15日 · The obturator nerve is a major peripheral nerve of the lower limb. In this article, we shall look at the anatomy of the obturator nerve – its anatomical course, functions and clinical correlations.

The obturator nerve in human anatomy arises from the ventral divisions of the second, third, and fourth lumbar nerves in the lumbar plexus; the branch from the third is the largest, while that from the second is often very small.

Provides sensory innervation to the medial upper thigh and provides articular branches to the hip and knee. The obturator nerve can become entrapped at the exit of the obturator canal or more distally by fascia, causing exercise-induced medial thigh pain, typically in athletes [1].

Once it reaches your groin area, your obturator nerve divides into three major branches: Anterior (front), provides sensation to muscles that help flex your hip. Cutaneous (skin), a further branch off of your anterior branch, provides sensation to your skin in the upper part of your inner thigh.

2023年7月24日 · These roots form the obturator nerve, which travels along the iliopectineal line and descends through the muscle fibers of the psoas major muscle. The nerve emerges from the medial border of the psoas major near the pelvic brim.

The obturator nerve is a branch of the lumbar plexus, which is formed within the psoas major muscle, by the union of the anterior divisions of the anterior rami of the second to fourth lumbar nerves (L2—L4). Following its origin, the obturator nerve descends through the substance of psoas major muscle.

2025年1月20日 · The obturator nerve is a major peripheral nerve arising from the lumbar plexus, primarily from the ventral divisions of the L2, L3, and L4 spinal nerves.[5] It is mainly responsible for the innervation of the adductor muscles of the thigh and provides some sensory innervation to the skin over the medial aspect of the thigh.

2016年10月19日 · the obturator decends through the substance of the psoas and exits medially near pelvic brim; behind common iliac vessels. passes behind common iliac vessels, lateral to the hypogastric vessels; anterior to obturator vessels. runs along lateral wall of lesser pelvis, anterior to the obturator vessels; enters obturator foramen. enters the ...

The obturator nerve is a major lower limb nerve derived from the anterior division of L2-L4 nerve roots and enters the pelvis along the obturator foramen and exits into the thigh anterosuperiorly along a 2- to 3-cm oblique tunnel, the obturator canal, and …
