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.

Gray rami communicantes connect to what two structures?
White rami communicantes (sing. ramus communicans) are literally white branches of communication between each spinal nerve and the sympathetic trunk. Their color is white because these lines of communication contain mainly myelinated nerve fibers of pre-ganglionic general visceral efferents from the spinal cord. Many of the pre-ganglionic nerve fibers synapse at the corresponding spinal segment level, and thus build a sympathetic ganglion at that level. Other pre-ganglionic white fibers either ascend or descend in the sympathetic trunk before synapsing in sympathetic ganglia above or below the spinal segment of origin. The sympathetic ganglia are literally knots in the sympathetic cord primarily containing cell bodies of the post-ganglionic neurons, whose axons are unmyelinated and gray in color. These unmyelinated post-ganglionic nerve fibers rejoin the spinal nerve at that level via the gray rami communicantes,as well as ascending or descending to adjacent levels. The white rami may also contain lightly myelinated sympathetic afferents whose cell bodies in the dorsal root ganglia synapse in the dorsal horn gray of the spinal cord. ANSWER: Carry preganglionic axons to the sympathetic chain
Are sypathetic preganglionic fibers contained in white rami communicantes?
yes
What collier is the Spinal Cord?
white
Are motor neuron cells bodies located in the gray or white matter of the spinal cord?
the white matter
What is the meaning of checkered spinal history?
Not sure of the origin, but a checkered history (or checkered past) means some good and some bad. Maybe it comes from the black and white colours of a chequer board ?

In the spinal cord which is deep to the other the white or gray matter?
in the spinal cord which is deeper to the other, the white matter or gray matter? how does this compare to the distrubution in the brain
What is the white matter of the spinal cord contain?
axons
What part of a muscle is usually attached to a fixed location?
A muscle insertion is the end of a muscle attached to the free-moving bone of its joint. A muscle origin is the end of the muscle attached to the relatively fixed bone of the joint.
What color is a spinal cord?
The spinal cord is mainly white, with a grey, butterfly shaped area of grey at its center.
What kind of matter do you have in your spinal cord?
grey and white. White matter of the spinal cord is composed of myelinated and unmyelinated fibers that allow communication between different parts of the spinal cord and between the cord and brain. Gray matter in the spinal cord looks like the letter H or a butterfly.
What color is spinal cord?
as far as im concern its white
