Cards

Term
Acetylcholine (Ach)
Definition
~Primary neurotransmitter of the parasympathetic nervous system; also present at somatic neuromuscular junctions and at sympathetic preganglionic nerves
Term
Acetylcholinesterase (AchE)
Definition
~Enzyme that degrades acetylcholine within the synaptic cleft, enhancing effects of the neurtransmitter
Term
Adrenergic
Definition
~Relating to nerves that release norepinephrine or epinephrine
Term
Adrenergic Antagonist
Definition
~Drug that blocks the actions of the sympathetic nervous system
Term
Alpha Receptor (a receptor)
Definition
~Type of subreceptor found in the sympathetic nervous system
Term
Anticholinergic
Definition
~Drug that blocks the actions of the parasympathetic nervous system
~parasympatholytic
~cholinergic or muscarinic blockers
Term
Autonomic Nervous System (ANS)
Definition
~Portion of the peripheral nervous system that governs involuntary actions of the smooth muscle, cardiac muscle, and glands
Term
Beta Receptor (B receptor)
Definition
~Type of subreceptor found in the sympathetic nervous system
Term
Catecholamines
Definition
~Class of agents secreted in response to stress that include epinephrine, norepinephrine, and dopamine
Term
Central Nervous System (CNS)
Definition
~Division of the nervous system consisting of the brain and spinal cord
Term
Cholinergic
Definition
~Relating to nerves that release acetylcholine
Term
Fight or Flight Response
Definition
~Characteristic set of signs and symptoms produced when the sympathetic nervous system is activated
Term
Ganglionic Synapse
Definition
~Region where 2 neurons meet in a ganglion
Term
Monoamine Oxidase (MAO)
Definition
~Enzyme that destroys norepinephrine in the nerve terminal
Term
Muscarinic
Definition
~Type of cholinergic receptor found in smooth muscle, cardiac muscle, and glands
Term
Myasthenia Gravis
Definition
~Motor disorder caused by a destruction of nicotinic receptors on skeletal muscles and characterized by profound muscular fatigue
Term
Nicotinic
Definition
~Type of cholinergic receptor found in ganglia of both the sympathetic and parasympathetic nervous systems
Term
Norepinephrine
Definition
~Primary neurotransmitter in the sympathetic nervous system
Term
Parasympathetic Nervous System (PNS)
Definition
~Portion of the autonomic nervous system that is active during periods of rest and results in the rest, digest, relax response
Term
Parasympathomimetics
Definition
~Drug that mimics the actions of the parasympathetic nervous system
~cholinergic
~produce rest and digest
Term
Peripheral Nervous System (PNS)
Definition
~Division of the nervous system containing all nervous tissue outside the CNS, including the autonomic nervous system
Term
Postganglionic Neuron
Definition
~Neuron that receives an action potential from a preganglionic neuron
Term
Preganglionic Neuron
Definition
~Neuron that creates an action potential and sends it to a postganglionic neuron
Term
Rest and Digest Response
Definition
~Signs and symptoms produced when the parasympathetic nervous system is activated
Term
Somatic Nervous System
Definition
~Nerve division that provides voluntary control over skeletal muscle
Term
Sympathetic Nervous System (SNS)
Definition
~Portion of the autonomic system that is active during periods of stress and results in the fight or flight response
Term
Sympatholytic
Definition
~Drug that inhibits the sympathetic nervous system; actions opposite of sympathomimetic functions of the body
~directly inhibits FOF
~adrenergic blocker
Term
Sympathomimetic
Definition
~Drug that stimulates or mimics the sympathetic nervous system
~produce fight or flight
Term
Synapse
Definition
~Junction between 2 neurons consisting of a presynaptic nerve, a synaptic cleft, and postsynaptic nerve
Term
Synaptic Transmission
Definition
~Process by which a neurotransmitter reaches receptors to regenerate the action potential
