|
|
A drug is called an agonist if it __________. |
Acts like the endogenous neurotransmitter by binding to its receptor |
|
|
Which type of drug would be an antidote to atropine poisoning? |

|
|
Which kind of drug would have anti-anxiety effects? |
muscarinic agonist |
|
|
Which type of drug could be used to treat asthma by opening airways wider? |
Sympathomimetic drug |
Mimics affects of sympathetic nervous system stimulation. |
|
Agonist |
Any exogenous substance that binds to a receptor and produces a similar effect to the endogenous ligand. |
|
|
Antagonist |
Any exogenous substance that binds to a receptor and produces an opposing effect to the endogenous ligand. |
|
|
Anticholinergic Drugs |
Drugs that interrupt or reduce the function of the parasympathetic nervous system. |
|
|
Endogenous Chemical |
Substance produced and released within the body to interact with a receptor protein. |
|
|
Exogenous Chemical |
Substance from a source outside the body, whether it be another organism such as a plant or from the synthetic processes of a laboratory, that binds to a molecular drug target |
|
|
Mydriasis |
Dilation of the pupil |
|
|
Parasympathomimetic drugs |
Drugs that enhance and/or mimic the function of the parasympathetic nervous system |
|
|
Sympatholytic drug |
Drug that interrupts, or ‘lyses’ the function of the sympathetic nervous system |
|
|
Sympathomimetic drug |
Drug that enhances or mimics the function of the sympathetic nervous system. |
|
|
Which drug can be used as an antidote for cholinesterase poisoning or poisoning by mushrooms containing muscadine? |
Atropine |
|
|
The main hormones of the adrenal medulla include: |
Dopamine, Adrenaline & Noradrenaline |
Fight or Flight response |
|
Cholinergic |
Pertaining to, activated by, or having the same function as acetylcholine. |
|
|
Post synaptic neuron |
The nerve cell the bears receptors for neurotransmitters release into the synaptic cleft by the presynaptic neuron |
|
|
Ganglion |
A cluster of interconnecting nerve cells outside the brain |
|
|
Parasympathetic |
Relating to the part of the autonomic nervous system that inhibits or opposes the effects |
|
|
Cholinergic Crisis |
Over stimulation at neuromuscular junction due to an excess of acetylcholine (AChE) as a result of the inactivity of AChE enzyme (acetylecholinesterase), which usually breaks down acetylcholine |
|
|
Efferent |
Neurons that send impulses from the central nervous system to limbs and organs. ie. controls motor function |
|
|
Efferent |
Neurons that send impulses from the central nervous system to limbs and organs. ie. controls motor function |
|
|
Afferent |
Neurons that receive information from our sensory organs (ie. skin, eyes) and transmit this input to central nervous system |
|
|
Activation of the Sympathetic nervous system results in: |
Fight/Flight response, pupil dilation, inhibition of digestion, increased hepatic glucose output, release of adrenaline/noradrenaline, contraction of rectum, release of bladder, bronchodilation, increased HR + BP |
