Cards

Term
Antagonist 
 Definition

an antagonist acts against and blocks an action.
Term
Acetylcholinesterase
 Definition
enzyme responsible for the immediate breakdown of acetylcholine when released from the nerve ending; prevents overstimulation of cholinergic receptors.
Term
Cholinergic
 Definition
responding to acetylcholine; refers to receptor sites stimulated by acetylcholine, as well as neurons that release acetylcholine.
Term
Anticholinergic
 Definition

drug that opposes the effects of acetylcholine at acetylcholine-receptor sites.
Term
Miosis 
 Definition
constriction of the pupil; relieves intraocular pressure in some types of glaucoma
Term
Mydriasis
 Definition
relaxation of the muscles around the pupil, leading to pupil dilation.
Term
Nerve gas 
 Definition
irreversible acetylcholinesterase inhibitor used in warfare to cause paralysis and death by prolonged muscle contraction and parasympathetic crisis
Term
Cholinergic crisis 
 Definition
is an over-stimulation at a neuromuscular junction due to an excess of acetylcholine (ACh), as of a result of the inactivity (perhaps even inhibition) of the Ach enzyme, which normally breaks down acetylcholine  
Term
Belladonna
 Definition

a plant that contains atropine as an alkaloid; used to dilate the pupils as a fashion statement in the past; used in herbal medicine much as atropine is used today.
Term
Myasthenic crisis 
 Definition

a lack of acetylcholine, usually caused by insufficient medication, which results in an inability to speak, breathe, or swallow in patients with myasthenia gravis.
Term
Parasympathomimetic 
 Definition

drug that mimics the parasympathetic nervous system PNS with the signs and symptoms seen when the PNS is stimulated.
Term
Dementia
 Definition

is a loss of brain function that occurs with certain diseases. It affects memory, thinking, language, judgment, and behavior.
Term
Cycloplegia
 Definition
 is paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation.
Term
Bronchodilating effect 
 Definition
a substance that dilates the bronchi and bronchioles, decreasing airway resistance and thereby facilitating airflow.
Term
Beta 1 selective adrenergic blocking agent 
 Definition

drugs that, at therapeutic levels, specifically block the Beta1-receptor in the sympathetic nervous system while not blocking the beta2-receptors and resultant effects on the respiratory system.
Term
Parasympatholytic
 Definition

a drug that lyses or blocks, the effects of the parasympathetic nervous system.
Term
Beta 2 selective adrenergic blocking agent 
 Definition
drugs that, at therapeutic levels, specifically block the Beta2-receptor in the sympathetic nervous system while not blocking the beta1-receptors and resultant effects on the respiratory system.
Term
Pheochromocytoma
 Definition
a tumor of the chromaffin cells of the adrenal medulla, which periodically releases large amounts of norepinephrine and epinephrine in the system with resultant severe hypertension and tachycardia.
