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.
Which nerve plexuses serve the shoulder and arm?
brachial :)
From what plexus does the phrenic nerve arise?
cervical plexuses
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
What are the 4 major nerve plexuses?
cervical brachial lumbar sacral
What major nerve arise from the plexuses?
what major nerves arise from the coccygeal plexus
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.
Which of the nerve plexuses originates from ventral rami L1 through L4?
Lumbar Plexus
What are the two major intrinsic nerve plexuses of the enteric nervous system?
myenteric plexus and submucous plexus
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)
