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.
The second (postganglionic) motor neuron synapses on an effector. Preganglionic fibers release the neurotransmitter acetylcholine and postganglionic fibers release acetylcholine or norepinephrine. D. Somatic nervous system effectors are skeletal muscles, and ANS effectors include cardiac and smooth muscle, and glands.. The axons of the motor neurons of the somatic nervous system extend from the CNS synapse directly to an effector and release acetylcholine, whereas autonomic pathways consist of two sets of motor (efferent) neurons. 1.
