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.
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.
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)
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
Do all of the spinal ventral rami branch join one another lateral to the vertebral column to form complex nerve plexuses?
False
The ventral rami of spinal nerves c1 through t1 and t12 through s4 form plexuses which serve the?
Serve the motor and sensory needs of the muscles and skin of the limbs.
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.

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.
