Question
Chapter 15, Problem 13DYKB
Summary Introduction
To contrast and compare:
The parasympathetic and sympathetic postganglionic axons. Also, examine the length of the axon, myelination and the neurotransmitter involved.
Concept introduction:
ANS consists of both, the sensory and motor components. The motor component of the ANS is divided further into the sympathetic division and the parasympathetic division. Myelination means the presence of myelin sheath in the axon of a neuron.

Students have asked these similar questions
Compare and contrast the postganglionic axons of the parasympathetic and sympathetic divisions. Examine the axon length, myelination (or lack thereof), and the neurotransmitter used.
In the sympathetic division of the autonomic
nervous system:
Select one:
The ratio between the number of
postganglionic and preganglionic neurons
is small.
A single preganglionic neuron usually
synapses with a single postganglionic
neuron.
An important functional characteristic is
convergence of the preganglionic fibers.
Preganglionic fibers are usually much longer
than the postganglionic fibers.
Activity of the neurons tends to have a more
generalized and widespread effect on the
body.
Compare and contrast the basic anatomy of the parasympathetic and sympathetic systems, includingcentral nervous system locations, ganglia locations, pre- and post-ganglionic neuron relative lengths,and ganglionic and effector neurotransmitters.
