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.
What spinal nerve serves the diaphragm?
Phrenic nerves from brachial and cervical plexus.
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.
Which spinal nerves go directly to the tissues they supply rather than forming a plexus?

What are the submucosal plexus and myenteric plexus?

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.
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 Network of spinal nerves that supplies the pelvis and legs?
lumbosacral plexus
Spinal nerves exiting the cord from the level of L4 to S4?
Lumbar plexus
What is formed by the spinal nerves exiting the cord from the level of L4 to S4?
Spinal nerves exiting the spinal canal between L4 and S4 collectively make up the sacral plexus.
What spinal nerve serves the diaphragm?
Phrenic nerves from brachial and cervical plexus.
What is the spinal nerves related to the sacral plexus?
It provides innervation to the pelvis, its organs and the lower limb
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.
Which spinal cord plexus supplies the abdominal wall?
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.
