Summary Introduction

To review:

Match the term obturator nerve with the most closely related description given below:

Tracts and columns

Specific region of body surface

Cervical plexus

Motor neuron axons

Sacral plexus

Lumbar plexus

Single bundle of axons

Involuntary motor response

Loose connective tissue, adipose tissue

Pectoral girdle/upper extremity

Introduction:

The obturator nerve is one of the nerves of the lumbar plexus. It starts from the L2 and ends at L4 of the ventral rami. Its function is to receive sensory signals from the middle surface of the thigh. It supplies muscles, such as the obturator externus, adductor magnus, gracilis externus, and the brevis.
