Ventral rami of spinal nerves C1 through T1 and T12 through S4 take part in forming?

∙ 13y ago
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)

Which spinal nerves go directly to the tissues they supply rather than forming a plexus?
T2 through T12
Fiber type in anterior ramus?
alpha spinal motor neuron axons leave the spinal column and enter the nerves via the ventral rami.
What are the large bundle of nerves caled extending from the brain through the spinal column?
The large bundle of nerves extending from the brain through the spinal column is called the spinal cord. The spinal cord connects the brain to the rest of the body.
Damage to the ventral roots of the first five thoracic spinal nerves on the right side of the body would interfere with the ability to?
dilate right pupil
Distinguish between the dorsal and ventral horn?
The tips of the anterior horns are broader and less tapered than those of the posterior horns. Human Anatomy & Physiology Laboratory Manual Ninth Edition Elaine N. Marieb & Susan J. Mitchell
The ventral rami of spinal nerves c1 through t1 and t12 through s4 take part in forming?
plexuses
Is true Both spinal and cranial nerves have dorsal and ventral roots?
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
Dorsal and ventral nerves of each spinal nerve unite to form what?
spinal nerve
What is effaces the ventral thecal sac?
It is where the nerves go and spinal fluid is and protects spinal cord
Which spinal nerves do not form plexus?
The spinal nerves that originate from the thoracic portion of the spinal cord don't form plexuses. The word thoracic pertains to the thorax.
What spinal nerve is made of?
Spinal nerves (aka mixed spinal nerves) are formed from the dorsal and ventral roots coming out of the spinal cord.A spinal nerve is made of mixed nerves. They have both sensory and a motor aspect. The roots of sensory fibers are on the dorsal side of the spinal cord.

Which spinal nerves go directly to the tissues they supply rather than forming a plexus?
T2 through T12
Is a interlacing of ventral rami and give rise to alternative pathways for the conduction of impulses?
spinal nerves
What region of the body is served by the ventral rami of spinal nerves?
The ventral rami serves as a form of intercostal nerves, which supply the muscles between the ribs and the skin and muscles of the anterior and lateral trunk.
The anterior root and the posterior root fuse to form?
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
Fiber type in anterior ramus?
alpha spinal motor neuron axons leave the spinal column and enter the nerves via the ventral rami.
