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.

What part of the peripheral nervous system is controlled largely outside of our awareness and regulates the activity of cardiac and smooth muscles, organs, and glands? A. Parasympathetic B. Somatic C. Autonomic D. Sympathetic

Select all correct descriptions of the motor pathways within the somatic division of the peripheral nervous system.Multiple select question.Fibers are carried by most cranial and all spinal nerves.The neurotransmitter is acetylcholine.Two neurons carry messages.Control is always involuntary.Effectors are skeletal muscles.

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

The autonomic nervous system controls the involuntary action of the body. It mainly controls and integrates the functions of internal organs like heart, blood vessels, glands, smooth muscles and uterus in the body. The autonomic nervous system is subdivided into (i) sympathetic and (ii) parasympathetic system. The organs receive nerves from both sympathetic and parasympathetic nerve fibers. They have antagonistic effects on the organs if one is stimulatory, the other is inhibitory.

The parasympathetic nervous system:Is the "fight or flight" divisionIs one of the two subdivisions of the autonomic nervous systemIs part of the sensory nervous systemAllows the control of skeletal muscle only
