a receptor (alpha or beta) or an effect related to the sympathetic nervous system
adrenergic
inflowing; conducting toward an area such as the CNS
afferent
a receptor subtype of the sympathetic nervous system
alpha receptor
involuntary nervous system that includes the parasympathetic and sympathetic divisions; regulates physiologic function of internal organs
ANS autonomic nervous system
a receptor subtype of the sympathetic nervous system
beta receptor
drugs (agonists) synthesized from tyrosine (dopamine, norepinephrine, epinephrine) that stimulate the sympathetic nervous system
catecholamines
a receptor (muscarinic or nicotinic) or an effect related to the parasympathetic nervous system
cholinergic
the specific tissue stimulated to act by the postganglionic nerve
effector organ
outflowing; conducting outward from a given are, such as the CNS
efferent
to supply with nerves
innervate
a receptor subtype of the parasympathetic nervous system
muscarinic receptor
a small peptide molecule released by presynaptic cells in response to electrical signals that diffuses across the synaptic cleft and subsequently binds to membrane receptors of postsynaptic cells, producing an excitatory or inhibitory effect
neurotransmitter
a receptor subtype of the parasympathetic nervous system
nicotine receptor
the first drug in a class of drugs to which all other drugs in the same class are compared
phototype
an automatic motor response to sensory stimuli
reflex arc
a part of the peripheral nervous system that controls voluntary skeletal muscle activity and conducts information
