Which spinal nerves comprise the brachial plexus and the lumbosacral plexus?
the spinal nerves which comprise the brachial plexus are C5 - C8 and T1. lumosacral plexus are L1 - L5, S1 - S4 and SR.
The major plexuses of the spinal cord?
Cervical Plexus Brachial Plexus Lumbar Plexus Sacral Plexus
What major nerve plexus serves the arm muscle?
Spinal chords
What is the spinal cord feature associated with the leash of nerves supplying the upper limbs?
The brachial plexus is the spinal cord feature associated with the leash of nerves supplying the upper limbs.
What is the brachial plexus?
The Brachial Plexus is the nerve plexus from which supplies the upper limb. Its root supply is C5 to T1. This means that the nerves which make it up leave the spinal chord at all the vertebrae between the 5th Cervical Vertebrae and the 1st Thoracic Vertebrae. Brachial plexus is a radical regrouping of the nerve fibers that are araising from the vental rami of C7 to C8 and additionally from T1. Through this network of nerves the entire upper limb will get its nerve supply.
What spinal nerve serves the diaphragm?
Phrenic nerves from brachial and cervical plexus.
What pathway is used to innervate the pinky finger?

Where does enlargements of the spinal cord occur?
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.
What is a benefit of a nerve plexus?
A plexus is a branching network of axons outside of the central nervous system. The four primary nerve plexuses are the cervical plexus, brachial plexus, lumbar plexus, and the sacral plexus. The choroid plexus is a part of central nervous system in the brain and it consist of capillaries, ventricles and ependymal cells. source of this information : Wikipedia.
What are the submucosal plexus and myenteric plexus?
Network of spinal nerves
What is the function of the cervical plexus?
The brachial plexus is a network of nerves fibers that connects the arm to the spinal cord. Injury of it could cause the arm to be paralyzed, a lack of muscle control, and/or a lack of sensation.
What is the brachial plexus group?
This group of nerves innervates the muscles and skin of the entire upper limbs except the Trapezius muscle and the skin near the axilla (arm pit). The plexus comes off the spinal cord at C4,C5,C6,C7,C8 and T1 where they mix and form a plexus. There are 5 main nerves that are formed: Musculocutaneous, axillary, radial, median and ulnar nerves.
