Which sympathetic pathway involves a preganglionic neuron that synapses with a ganglionic neuron in a sympathetic trunk ganglion,but the postganglionic axon does not leave the trunk via a gray ramus

Activation of parasympathetic fibers in pelvic splanchnic nerves leads to

There are ________ prevertebral ganglia.

Which type of innervation causes the heart rate to increase

The somatic nervous system can both excite and inhibit effectors.

The sympathetic division of the ANS has

The abdominal _______ plexus consists of the celiac plexus,superior mesenteric plexus,and inferior mesenteric plexus.

The lack of extensive divergence of parasympathetic preganglionic axons prevents the mass activation seen in the sympathetic division.

Which division functions to increase alertness and direct bodily responses in stressful situations

An axon takes the ______ nerve pathway if a preganglionic neuron synapses with a ganglionic neuron in a sympathetic trunk ganglion.

The micturition reflex results in

Catecholamines include

Motor neurons of the _________ nervous system contain more rapidly conducting axons.

Postganglionic axons are

Norepinephrine is a catecholamine.

Which division functions to conserve energy and replenish the supply of nutrients

In the parasympathetic division,_________ ganglia are located in the wall of the target organ.

In an autonomic motor pathway,the first cell in the two-neuron chain is the ______ neuron.
