Which branch of the spinal nerve is involved in Plexus formation?
Which branch of the spinal nerve is involved in Plexus formation?
It is located in the lumbar region, within the substance of the psoas major muscle and anterior to the transverse processes of the lumbar vertebrae. The plexus is formed by the anterior rami (divisions) of the lumbar spinal nerves L1, L2, L3 and L4. It also receives contributions from thoracic spinal nerve 12.
What is the benefit of nerve plexus?
These bundles typically originate from the same anatomical area and serve specific areas of the body. Bundles of nerves that form a plexus communicate information to your brain about pain, temperature, and pressure. These nerve plexuses also send messages from the brain to the muscles, allowing for movement to occur.
What does the obturator nerve control?
The obturator nerve is responsible for the sensory innervation of the skin of the medial aspect of the thigh. The nerve is also responsible for the motor innervation of the adductor muscles of the lower limb (external obturator.
What does the obturator nerve pass through?
The obturator nerve is derived from L2-4 and travels along the medial border of the psoas muscle; it is both a motor and a sensory nerve. It travels through the obturator foramen with the obturator artery and vein into the thigh. The obturator nerve divides into anterior and posterior branches.
What muscles does the obturator nerve supply?
Overview. Motor functions: Innervates the muscles of the medial compartment of the thigh (obturator externus, adductor longus, adductor brevis, adductor magnus and gracilis). Sensory functions: Cutaneous branches of the obturator nerve innervate the skin of the medial thigh.
Which of the following muscles is partially paralyzed when obturator nerve is damaged?
The nerve provides motor function to most of the adductor muscles of the hind limb. The nerve has no sensory function. Partial or complete paralysis affects the adductor muscles, with consequent loss of function.
What nerve affects the groin area?
Nerve Problem 10 This condition is called lumbar radiculopathy. Likewise, nerve entrapment, such as obturator nerve or ilioinguinal nerve entrapment, may cause burning or lancinating groin and middle thigh pain, as well as other neurological symptoms like numbness and tingling.
