What major nerve arise from the plexuses?
what major nerves arise from the coccygeal plexus
What are the two major intrinsic nerve plexuses of the enteric nervous system?
myenteric plexus and submucous plexus
The phrenic nerve arises from the?
The phrenic nerve arises from the spinal cord at C3, C4, and C5 nerve levels. It originates from the cervical plexus and innervates the diaphragm muscle, playing a crucial role in controlling breathing.
From what plexus does the phrenic nerve arise?
cervical plexuses
Which nerve plexuses serve the shoulder and arm?
brachial :)
Which of the nerve plexuses serves the shoulder and arm?
Lumbar
What are the two primary nerve plexuses regulating digestive function?
Submucosal nerve plexus and myenteric nerve plexus
Which of the nerve plexuses originates from ventral rami L1 through L4?
Lumbar Plexus
Why is the formation of nerve plexuses a survival advantage?
Damage to a single spinal nerve will not completely paralyze a limb.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
Ventral rami of spinal nerves C1 through T1 and T12 through S4 take part in forming?
Except for T2-T12, all ventral rami branch and join one another lateral to the vertebral column, forming complicated interlacing nerve networks called nerve plexuses. Nerve plexuses occur in the cervical, brachial, lumbar, and sacral regions and primarily serve the limbs (MarieB, 2010 8th ed. pp. 502)
What kind of digestive tract neural reflex involves only the nerve plexuses that lie in the walls of the digestive tract itself?
short reflexes
