rami communicantes उदाहरण वाक्य

Their difference in coloration is caused by differences in myelination of the nerve fibres contained within, i . e . there are more myelinated than unmyelinated fibres in the white rami communicantes while the converse is true for the grey rami communicantes.
Slightly myelinated preganglionic fibers ( aka visceral efferent fibers ) leave the lateral grey column through the ventral roots and promptly form fourteen aggregates called white rami communicantes, also known as white communicating rami, which eventually enter the sympathetic trunk, a structure next to the vertebral column that consists of paired chains of sympathetic ganglia connected by nerve fibers.
The lateral grey column receives input signals from preganglionic, myelinated fibers from viscera ( internal organs ), which course through prevertebral ganglia ( between the visceral organ and the sympathetic chain ) and paravertebral ganglia ( in the sympathetic chain ), white rami communicantes, and dorsal roots to synapse on cells of the intermediolateral cell column in the lateral horn.
The "'meningeal branches of the spinal nerves "'( also known as "'recurrent meningeal nerves "', "'sinuvertebral nerves "', or "'recurrent nerves of Luschka "') are a number of small nerves that branch from the spinal nerve near the origin of the anterior and posterior rami, but before the rami communicantes branch.
