Where do most of the nerve fibers of the sympathetic division of the autonomic motor pathways arise from?Multiple Choicethoracolumbar spinal nervescranial nervesbrain stemcervical nervesmedulla oblongata

Which nerves carry sympathetic signals out of the central nervous system?Group of answer choicesThoracic and lumbar spinal nervesCranial nerves and sacral spinal nervesCervical and coccygeal spinal nerves

The autonomic nervous system can be readily divided into:Group of answer choicesfour divisions: – the sympathetic, parasympathetic, enteric and vagal sensorytwo divisions – the sympathetic and parasympatheticfive divisions – the sympatethetic, parasympathetic, enteric, spinal sensory and vagal sensoryfour divisions – the sympathetic, parasympathetic, enteric and spinal sensorythree divisions – the sympathetic, parasympathetic and enteric

Select all correct descriptions of the autonomic motor pathways of the peripheral nervous system.Multiple select question.Parasympathetic nerves originate from thoracolumbar spine.The neurotransmitter is always acetylcholine.Effectors are smooth and cardiac muscle and glands.Control is involuntary.There are two neurons per message.

The preganglionic neurons of the sympathetic division begin in the and regions of the spinal cord.

The first neuron of the efferent motor pathway of the sympathetic and parasympathetic divisions has its cell body in the nervous system.
