Preganglionic fibers of the parasympathetic division of the ANS synapse with the?
Their corresponding Postganlionic fibres.
What is the site of axons and afferent neurons?
AnswerThe thalamus is the important synapse site for afferent fibers traveling to the sensory cortex.
What are the 5 cells located in the occipital lobe?
axons of the ganglion cells leave the eyeball as the optic nerve. At the optic chiasma, the medial fibers of each eye cross over to the opposite side. The fiber tracts formed are called optic tracts. The optic tracts synapse with neurons in the lateral geniculate nucleus of the thalamus, whose axons form the optic radiation, terminating in the visual cortex of the occipital lobe of the brain.
Which cranial nerve forms a midline connection allowing fibers to cross to the opposite side of the brain?
thalamus
What are the function of the nerve fibers?
Arevbranching fibers at the end of the axon that lead the nervous impulse from the axon to the synapse
Synapse site for afferent fibers to sensory cortex?
Thalamus
What is an important synapse site for afferent fibers traveling to the sensory cortex?
The thalamus.
Important synapse site for afferent fibers traveling to the sensory cortex?
thalamus Also, the gray matter in the dorsal horn of the spinal cord.
What is the name of the synapse site in the brain for afferent fibers that travel to the sensory cortex?
i think it is the choroid plexus....not for sure though ---- Afferent sensory fibers (those returning to the brain from the periphery) synapse first in the posterior horn of the spinal cord, ascend one to two levels and decussate (cross over) at the anterior white commissure before their axons migrate to the anterior or lateral spinothalamic tracts. These then synapse again in the thalamus for integration before they go on to the post-central gyrus - the sensory cortex - and other sites in the cortex.
Nerve fibers of the olfactory tracts lead to?
The olfactory tract is split into medial and lateral. Their projections are to 5 different areas of the brain- anterior olfactory nucleus, olfactory tubercle, Piriform cortex, Amygdala, Entorhinal cortex The lateral tract originates from the olfactory epithelium separates into mitral cells and tuft cells. mitral cells synapses onto all 5 of the regions to ultimately synapse onto the orbitofrontal cortex via the thalamus or the frontal cortex. tufted cells on the other hand only synapse onto the anterior olfactory nucleus and the olfactory tubercle The medial or vomeronasal tract projects to mitral cells that synapse only to the Amygdala

What connects gray matter on the left and right sides of the spinal cord?
That sounds as if it is a brain. Another answer: It is the Thalamus. The thalamus consists of two lateral masses of neural tissue that are joined by a narrow isthmus of neural tissue called the intermediate mass.
Direction in which the muscle fibers run relative to some imaginary line?
These muscle fibers are said to be lateral.
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
