High Yield Terms to Know Flashcards
Adrenergic
A nerve ending that releases NE as the primary transmitter, also, a synapse in which NE is the primary transmitter
Adrenocrecptor, adrenergic receptor
A receptor that binds, and is activated by, one of the catecholamine transmitters or hormones (NE, EE, Dopamine) and related drugs
Baroreceptor reflex
The neuronal homeostatic mechanism that maintains a constant arterial blood pressure; the sensory limb originates in the baroreceptors of the carotid sinus and aortic arch; efferent pathways run in parasympathetic and sympathetic nerves
Cholinergic
A nerve ending that releases acetylcholine; also, a synapse in which the primary transmitter is acetylcholine
Cholinoceptor, cholinergic receptor
A receptor that binds and is activated by acetylcholine and related drugs
Dopaminergic
A nerve ending that releases dopamine as the primary transmitter; also a synapse which dopamine is the primary transmitter
Homeostatic Reflex
A compensatory mechanism for maintaining a body function at a predetermined level, for example Baroreceptor for BP
Nonadrenergic, noncholinergic (NANC) system
Nerve fibers associated with autonomic nerves that release purines or peptides, not NE or ACh
Parasympathetic
The part of the ANS that originates in the CN and sacral part of the spinal cord; the craniosacral autonomic system
Postsynaptic receptor
A receptor located on the distal side of a synapse, for example on a postganglionic neuron or autonomic effector cell
Presynaptic receptor
A receptor located on the nerve endings from which the transmitter is released into the synapse; modulates the release of transmitter
Sympathetic
The part of the autonomic nervous system that originates in the thoracic and lumbar parts of the spinal cord
