The cell bodies for preganglionic neurons are located in either the brainstem or spinal cord, and their axon terminals are located in autonomic ganglia. The preganglionic neurons are located in specific cell groups (also called nuclei) in the brainstem or in the lateral horns of the spinal cord at sacral levels. The cell bodies of parasymapathetic preganglionic neurons are located in the homologous motor nuclei of the cranial nerves. brainstem cervical region of the spinal cord. Question 16 The cell bodies of parasympathetic preganglionic neurons are located in the... % .check all that apply Selected Answers: Answers: brainstem lateral gray horns between the T1 and L2 segments of the spinal cord. The cell bodies of the presynaptic neurons of both the parasympathetic and sympathetic systems are located within the central nervous system. lateral gray horns of the sacral region in the spinal cord. Significantly, the axons of the postganglionic neurons are not myelinated, … The cell bodies of the postganglionic neurons are in autonomic ganglia located peripherally. Most of the cell bodies of the postganglionic neurons, that are found along the vertebral column. Its motor component consists of preganglionic and postganglionic neurons. ; cholinergic: Pertaining to, activated by, producing, or having the same function as acetylcholine. Visceral efferent (VE) pathways that innervate smooth muscle, cardiac muscle, and glands involve two neurons and a synapse within an autonomic ganglion.The cell bodies of the preganglionic neurons are in the brainstem or spinal cord of the central nervous system (CNS). In parasympathetic nervous system. ; adrenergic: Containing or releasing adrenaline. ; postganglionic neuron: A nerve cell that is located distal or posterior to a ganglion. The preganglionic axon found in the neuron synapses with the second motor neuron, which is the postganglionic neuron. Furthermore, postganglionic neurons do not contain any structural component in the central nervous system and their cell bodies and dendrites occur in the autonomic ganglia. A cluster of cell bodies of sympathetic or parasympathetic neurons located outside the central nervous system. (There is one exception, in the adrenal gland, which will be discussed later in this module.) These axons synapse on the cell bodies of postganglionic neurons which are located in all cases outside the CNS. The postganglionic neuron’s cell body is in an autonomic ganglion outside the central nervous system. The postganglionic axon, found in this neuron, stretches to the effector organ. These presynaptic autonomic neurons synapse only with postsynaptic autonomic neurons. Key Terms. parasympathetic nervous system. Option : Near the target cell is correct The cell bodies of postganglionic parasympathetic neurones are located very close to view the full answer Previous question Next … postganglionic fiber: In the autonomic nervous system, these are the fibers that run from the ganglion to the effector organ. Postganglionic neuron: The second autonomic motor neuron in an autonomic pathway - having its cell body and dendrites located in an autonomic ganglion and its unmyelinated axon ending at cardiac muscle - smooth muscle - or a gland. Extends beyond the thoracic and lumbar spinal cord, from the superior … The axons of preganglionic neurons are mostly myelinated, relatively slow-conducting fibers. lateral gray horns between the T1 and L2 segments of the spinal cord. In the ganglia, a neuron-to-neuron synapse relays information to the cell body of a postganglionic neuron.
