Document Summary
Comparison of the somatic and autonomic nervous systems. If somatic motor neurons cease to stimulate a muscle, the result is a paralyzed, limp muscle that has no muscle tone. Includes association, mostly with, interoceptors (receptors inside the body), such as chemoreceptors that monitor blood co2 level, and mechanoreceptors that detect the degree of stretch in the walls of organs or blood vessels. These sensory signals are not consciously perceived most of. Si: matthew landry mland84@lsu. edu the time, but may cause conscious sensations from intense activation: the autonomic motor division includes components that initiate and transmit nerve impulses from the cns to cardiac muscle, smooth muscle, and glands. Comparing motor neurons between the sns and ans. In the sns, the only neurotransmitter released is acetylcholine (ach). In the ans, the neurotransmitter(s) released is/are: preganglionic axons release ach and postganglionic axons release either ach or norepinephrine (ne).
