What else can I help you with?
What spinal cord location would you find the origin of the white rami communicantes.?
The white rami communicantes are myelinated pre-ganglionic fibers (myelinated axons) from cell bodies located in the internal gray of the spinal cord. These fibers represent general visceral efferents of the sympathetic nervous system.
Does the white rami communicans contain fibers of a preganglionic or postganglionic neurons?
Preganglionic because they are myelinated. FALSE
Which nerve is responsible for regulating visceral activity?
Spinal accessory
Do all visceral motor neurons synapse in a sympathetic ganglion?
No; some axons synapse in nearby autonomic ganglion. postganglionic fibers travel along either sympathetic nerves or rejoin at the spinal nerve.
What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
Does the spinal cord have a backbone?
The spinal cord is a bundle of nerve fibers which is inside of the vertebrae (backbones).
What part of the spinal nerve consists of motor fibers leaving the spinal cord?
The ventral root.
The gray matter of the spinal cord?
Is located within the spinal cord and contains unmyelinated fibers.
What fibers do ventral spinal cord roots contain?
The ventral roots contain motor fibers.
What is parasypathetic?
Parasympathetic stimulation is a process that takes place in the peripheral nervous system. This is a process where signals are carried throughout the body.
Afferent nerve fibers enter the part of the spinal cord called?
Afferent nerve fibers enter the spinal cord through the dorsal roots.
Which is the correct spelling-spinal chord or spinal cord?
spinal cord
