| 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) |
