1
New cards

ionotropic

fast and short lived

example: glutamate and gaba

2
New cards

metabotropic

slower and long lasting

effects can start 20 m/s after release and last minutes or longer

suited for smell and pain

involve neurotransmitter attaching to receptor and causing a G protein to be released which activates a second messenger

3
New cards

neuropeptides

slow and long lasting

released by dendrites, cell body, axon

requires repeated stimulation

associated with hunger, thirst, fear

4
New cards

hormones

chemical messengers that your body uses to communicate between different parts

Example: growth, metabolism, mood, and reproduction

5
New cards

hormones in hypothalamus

1 brain centers activate the hypothalamus

2 the hypothalamus secretes thyroid releasing hormone

3 TRH is picked upby the anterior pituitary gland which stimulates TSH

4 TSH causes the thyroid to be released

5 thyroid regulates breathing, heart race, body temp, and more
