Question Answer
Receptor Blockage The blockage of receptor stimulation and it’s effects.
Enzyme Inhibition The interference with the production of certain mechanism-enabling enzymes.
What are the components of the CNS? Brain & Spinal Cord
What are the components of the PNS? Inludes sensory, sympathetic and parasympathetic nerves.
AcH – Acetylocholine A chemical produced by the body that is used in the transmission of nerve impulses. It is destroyed by the enzyme cholinesterase.
What neurons lack snapses so they go directly from the CNS to the sensory reception site? Sensory & Motor
What are the neuromuscular blocking agents? Pavulon & Curare
Anticholinergic Refers to a drug blocking a receptor for acetylcholine.
Ganglion Mass of nervous tissue composed primarily of the neuro cell bodies & lying outside the brain or spinal cord.
Efferent Nerve Fibers Impulses that go away from the CNS to the various body parts.
Afferent Nerve Fibers Impulses that go to the CNS from the various body sites.
What system controls involuntary unconscious mechanisms of the body? Autonomic Nervous System
What are the 2 branches of the Autonomic Nervous System? Sympathetic and Parasympathetic
Adrenergic Refers to a drug stimulating a receptor for norepinephrine or epinephrine.
Muscarinic Receptors Stimulates AcH receptors at the Parasympathetic sites.
Nicotinic Receptors Stimulates AcH receptors at other locations including the Parasympathetic sites.
What is the 1st step in the sequence of the stimulation of Sympathetic (Adrenergic) receptors? Receptor stimulation
What is the 2nd step in the sequence of the stimulation of Sympathetic (Adrenergic) receptors? Production of adenyl cyclase
What is the 3rd step in the sequence of the stimulation of Sympathetic (Adrenergic) receptors? ATP Converts to cyclic AMP
What is the 4th step in the sequence of the stimulation of Sympathetic (Adrenergic) receptors? Cyclic AMP produces bronchodilation
COMT (Catechol O-methyltransferase) Rapidly breaks down or inactivates drugs such as epinephrine.
MAO (Monoamine Oxidase) It does the same thing as COMT, but is found in the intestines.
Cholinergenic Refers to a drug causing stimulation of a receptor for acetylcholine.
Sympatholytic An agent blocking the effect of the sympathetic nervous system.
Sympathomimetic An agent causing stimulation of the sympathetic nervous system.
