Study Notes

Autonomic Nervous System Anatomy and Function

Autonomic neurons are associated with interoceptors, such as chemoreceptors and mechanoreceptors.
Autonomic motor pathways consist of two motor neurons in series.
The first neuron is the preganglionic neuron with its cell body in the CNS, and its myelinated axon extending to an autonomic ganglion.
The second neuron is the postganglionic neuron with its cell body in the autonomic ganglion and an unmyelinated axon extending to the effector.
In some autonomic pathways, the preganglionic neuron extends to specialized cells of the adrenal medullae called chromaffin cells.
Autonomic motor neurons release either acetylcholine (ACh) or norepinephrine (NE).
Sympathetic and parasympathetic divisions are the two divisions of the autonomic nervous system.
Most organs have dual innervation, receiving impulses from both sympathetic and parasympathetic neurons.
Sympathetic activities prepare the body for emergency situations, resulting in increased alertness and enhanced metabolic activities.
Responses to stress include rapid heart rate, faster breathing rate, and dilation of blood vessels to organs involved in combating stress.
The majority of the output of the sympathetic division is directed at the smooth muscle of blood vessels.
The release of glucose from the liver is part of the body's response to stress.
