| Question |
Answer |
| Amines | class of neurotransmitters derived from Amino Acids |
| Catecholemines | subgroup of amine neurotransmitters - dopamine, norepi, epi |
| dopamine | subgroup of catecholeamine, effects CNS |
| dopamine made in... | midbrain - substancia niagra |
| Norepi | subclass of catecholemines - effect CNS & PNS |
| MAO/COMT | enzymes that degrade catecholemines |
| epi | made in adrenal medulla |
| seratonin | subgroup of amine NT's, found in CNS, regulates sleep, effects emotions |
| histamine | (blank) |
| Cholenergic Muric Neuron | Produces ACH |
| ACHE | degrades ACH - Enzyme |
| Brokendown ACH | choline & acetate |
| recycled B vitamins | choline |
| nicatinic receptor | excitatory |
| muscarinic receptor | inhibitory |
| ACH can bind to... | nicatinic & muscarinic receptors |
| chatecholemines | dopamine, epinephrine & norepinephrine |
| sodium ions crossing the membrane | excitatory - epsp |
| chloride channels open | inhibitory - ipsp |
| hyperpolarize | making the cell more negative - less potential for a nerve impulse |
| calcium diffuses into | endbulbs of neurons |
| exocitosis | pumping out neurotransmitters |
| convergence | several presynaptic endbulbs w/ one post synaptic endbulb |
| reuptake | pulling back into endbulb to recycle |
| synaptic cleft | space btw two synapses (pre/post) |
| axosomatic | axon conected to the cell body |
| axodendritic | axon connected to the dendrite |
| axoaxonic | axon connected to another axon |
| gap junctions | electrical synapses that connect cells. One impulse travels to every cell. (ie the heart) |
