The postganglionic axons of the sympathetic branch of the ANS are considered short.

The micturition reflex results in

For the repolarization phase of an SA nodal cell action potential,

The somatic nervous system and the autonomic nervous system are part of both the peripheral nervous system and the central nervous system.

The arrector pili muscles receive their sympathetic innervation via the

The atria are separated from the ventricles externally by the

Terminal and intramural ganglia are associated with the parasympathetic branch of the ANS.

It is the contraction of the atria during atrial systole that completes the filling of the ventricles while the ventricles are in diastole.

Which statements are correct concerning the parasympathetic division of the ANS? a: Contains preganglionic cell bodies in brainstem nuclei b: Contains preganglionic cell bodies in the lateral horns of the T1–L2 regions c: Participates in the “fight-or-flight” response d: Helps maintain homeostasis e: Contains preganglionic cell bodies in the sacral region of the spinal cord
