Cervical: C1 - C5
Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.
Brachial: C5-T1
Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.
Lumbar: T12 - L4
Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.
Sacral: L4-S5
Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.

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 following is not a nerve plexus?
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.
From what plexus does the phrenic nerve arise?
The phrenic nerve arises from the cervical plexus, specifically from nerve roots C3, C4, and C5. It travels down through the thorax to innervate the diaphragm, playing a crucial role in breathing.
The submucosal and myenteric nerve plexuses that help regulate the mobility and secretory activity of the GI tract organs are both part of the?
The submucosal and myenteric nerve plexuses are both part of the enteric nervous system, which is a division of the autonomic nervous system located in the GI tract walls. They work together to coordinate and regulate the movement, secretion, and absorption processes in the gastrointestinal tract.
What are the 3 types of unencapsulated tactile receptors?
The three types of unencapsulated tactile receptors are free nerve endings, root hair plexuses, and tactile discs. Free nerve endings are found throughout the skin and detect pain and temperature. Root hair plexuses are located around hair follicles and detect hair movement. Tactile discs are found in the deeper layers of the skin and detect light touch and pressure.
Which nerve plexuses serve the shoulder and arm?
brachial :)
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
Why is the formation of nerve plexuses a survival advantage?
Damage to a single spinal nerve will not completely paralyze a limb.
What are the two primary nerve plexuses regulating digestive function?
The two primary nerve plexuses regulating digestive function are the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). They are part of the enteric nervous system and play important roles in controlling gastrointestinal motility, secretion, and blood flow.
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.

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.
What kind of digestive tract neural reflex involves only the nerve plexuses that lie in the walls of the digestive tract itself?
short reflexes
Do all of the spinal ventral rami branch join one another lateral to the vertebral column to form complex nerve plexuses?
False
