The soma is the cell body of the neuron that contains the nucleus and much of the other 'life' of the neuron. Dendrites and axons reach out from the soma to connect with other neurons.
Heavily myelinated axons of the somatic motor neurons extend from the CNS to the effector (lacks ganglia). Pathways in the ANS are a two-neuron chain âThe preganglionic (first) neuron has a lightly myelinated axon. The ganglionic (second) unmyelinated neuron extends to an effector organ via the postganglionic axon. Autonomic Pathways consist of a 2 neuron chain: The first motor neuron, called the preganglionic neuron, has its cell body in the CNS and its myelinated axon called the preganglionic fiber extends to autonomic ganglion.
