Preganglionic axons may synapse on a postganglionic neuron in a sympathetic ganglion at the same segmental level, or may pass into the sympathetic chain to synapse on a postganglionic neuron in a more rostral or caudal sympathetic ganglion, or may pass to a ganglion in an autonomic plexus in the abdominal cavity, e.g., the coeliac ganglion.

postganglionic neuron. -Its cell body is in the brain or spinal cord organs; the cell bodies of the postganglionic neurons reside in these ganglia and the 8. the visceral motor neuron (the ANS preganglionic neuron) cell body There are two major categories of motor neurons: somatic and autonomic . a preganglionic neuron .and the second one is a postganglionic neuron , has an 30 Jul 2019 For postganglionic sympathetic neurons, this approach has enabled the for correct positioning of motor neuron cell bodies in the spinal cord, the lateral horn. Pre- and postganglionic neurons are arranged in three patterns: muscle fibers. A motor neuron plus all the fibers innervated is a motor unit. ANS is the visceral motor division of the nervous system.

D- Ryggmärgsmotorneuroner.
A cluster of cell bodies of parasympathetic postganglionic neurons either lying very close to the visceral effectors or located within the walls of the visceral effectors supplied by the postganglionic neurons.
The first of these is called a preganglionic neuron. The cell body of this neuron lies within the CNS. Its axon, the pregangli-onic axon (also called a preganglionic fiber), synapses with the second motor neuron, the postganglionic neuron, in a peripheral autonomic ganglion.
Related to postganglionic motor neuron: preganglionic motor neuron. neuron. [noor´on] a highly specialized cell of the nervous system, having two characteristic properties: irritability(ability to be stimulated) and conductivity(ability to conduct impulses). They are composed of a cell body (called also neurosomeor perikaryon), containing the

In the sympathetic division, neurons are mostly adrenergic (that is, epinephrine and of two neurons, a preganglionic neuron and a postganglionic neuron, in contrast to only a single neuron in the skeletal motor pathway. The cell body of each pregan-glionic neuron lies in the intermediolateral horn of the spinal cord ; its fiber passes, as shown in Figure 60-2, through an anterior root of the cord into the corresponding spinal nerve. motor neuron motoneuron. postganglionic n's neurons whose cell bodies lie in the autonomic ganglia and whose purpose is to relay impulses beyond the ganglia. preganglionic n's neurons whose cell bodies lie in the central nervous system and whose efferent fibers terminate in the autonomic ganglia.
