Are sypathetic preganglionic fibers contained in white rami communicantes?
yes
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
What branches of spinal nerve contain autonomic fibers?
The rami communications
What branch of the spinal nerve contain autonomic fibers?
The rami communications
Does the gray rami communicans contain fibers of a preganglionic or postganglionic neurons?
could be preganglionic
Do the white communicating rami contain myelinated preganglionic sympathetic nerve fibers and are present in all apinal nerves?
Yes and No. White communicating rami contain mylinated preganglionic sympathetic nerve fibers, but are only present at the levels of spinal cord segments T1-L2 (where the cell bodies for these nerve fibers exist in the lateral horn of the spinal cord). Although the sympathetic fibers only arise in the T1-L2 spinal cord segments, they are dispersed to all spinal nerves by traveling through the sympathetic chain. The preganglionic sympathetic fibers will enter the sympathetic chain thru whit rami communicans and then do one of 4 things: 1. synapse with a postganglionic cell body in the sympathetic chain at the level it enters 2. ascend within the chain to synapse 3. descend within the chain to synapse 4. splanchnic nerves leave the chain without synapsing and synapse closer to the organ they innervate.There are, however, GRAY rami communicans for all spinal nerves.I hope that helps
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
What does non myelinated fibers look like?
Myelinated fibers appear white in comparison to unmyelinated fibers.
A fiber found in most connective tissues?
yellow fibers white fibers reticular fibers
What is Protein in white fibers?
Chondrocyte
What is the birth name of Rami Campbell?
Rami Campbell's birth name is Rami Kamaal Campbell.
