Term Definition
Sympathetic NS The part of the autonomic nervous system responsible for fight or flight reaction. Raises energy and metabolic rate
Parasympathetic NS the part of the autonomic nervous system that deals with energy conservation and lowering of the metabolic rate. Also called the cranialsacral division.
Ganglion dense mass of nerve cells outside the CNS.
Postsynaptic Neuron The synaptic cell where neurotransmitter is absorbed.
Presynaptic Neuron The synaptic cell where neurotransmitter release occurs.
Synapse The site where communication occurs between a nerve cell and some other cell.
Receptors Cells Cells that receive Neurotransmitters
Neurotransmitter A chemical compound release by one neuron to an affect the transmembrane potential of another.
Acetylcholine the dominant neurotransmitter in the peripheral NS.
Norepinephrine Noradrenalin. Neurotransmitter in the sympathetic division of the peripheral nervous system.
Catecholemines includes epinephrine, norepinephrine, and dopamine.
Epinephrine adrenalin.
Adrenergic Receptors receptor that receives epinephrine.
Cholinergic Receptors receptors that receive Acetylcholine.
Beta Receptors membrane receptors sensitive to epinephrine.
Alpha Receptors membrane receptors sensitive to epinephrine and norepinephrine.
Nicotinic Receptors Acetylcholine receptors that respond to the compound Nicotine.
Muscarinic Receptors membrane receptors sensitive to acetylcholine and to muscarine, a toxin produced by certain mushrooms.
Sympathetic Trunk the verves and ganglionic chain that composes the sympathetic nervous system.
Thorocolumbar division the sympathetic division of the autonomic nervous system.
Colateral Ganglia sympathetic ganglion situated anterior to the spinal column and separate from the sympathetic chain.
Celiac Ganglia ganglion near the celiac trunk. Fibers from this ganglion innervate the stomach, liver, gallbladder, pancreas, and spleen.
Superior Mesenteric Ganglia near the Superior Mesenteric Artery. Fibers innervate the small intestine and a proximal two thirds of the large intestine.
Adrenal Medulla core of adrenal gland. Secrets catecholamines into the blood during sympathetic activation.
Cardiac Plexus solar plexus. Where fibers from the Vagus nerve enter.
Inferior Mesenteric Ganglia innervates vicera within abdominal cavity.
Oculomotor Nerve cranial nerve 3, controls eye muscles.
Facial Nerve cranial nerve 7, that controls muscles of face and jaw.
Vagus Nerve carry sensory and motor neurons serving the heart, lungs, stomach, intestines, and various other organs.
Craniosacral Division division of the parasympathetic nervous system.
Glossopharyngeal Nerve cranial nerve 9, which activate the muscles of the tongue, pharynx, and parotid gland
