The lumbar plexus supplies the abdominal wall, external genitals, and part of the lower limbs. Arising from this plexus are the ilioinguinal, femoral, and obturator nerves.
The brachial plexus is the spinal cord feature associated with the leash of nerves supplying the upper limbs.
The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
The lumbar plexus contains nerve fibers that innervate the leg, and the sacral plexus contains nerve fibers that innervate the foot. The lumbar plexus arises from the lower spinal cord levels, while the sacral plexus arises from the sacral spinal cord levels.
The spinal cord is posterior to the chest.
The spinal nerve is not a nerve plexus. Nerve plexuses are complex interwoven networks of nerves that form in the peripheral nervous system, whereas spinal nerves are the mixed nerves that emerge from the spinal cord and are not organized in a plexus-like fashion.
Enlargement of the spinal cord can occur at any point along the spinal cord. Where depends upon the cause. These causes could be bacterial infection, structural changes in the vertebrae or a tumour. Less likely causes could be genetic birht defects.
The spinal nerves that originate from the thoracic portion of the spinal cord don't form plexuses. The word thoracic pertains to the thorax.
meningeal branch
Spinal nerves exiting the spinal canal between L4 and S4 collectively make up the sacral plexus.
Yes it is. It is located along the third and fourth ventricle of the brain. The choroid plexus creates the cerebrospinal fluid for the brain and spinal cord.
the cauda equina is the nerve that emerges from the distal end of the spinal cord. it also supplies the lower extremities.
