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.
