Flashcards in Nervous system pt 1 Neurotransmitter synaspe Deck (14):
1

Nuerons recieve and transmit stimuli by:

electro-chemical signals

2

Dendrites:

recive an impulse & condcut it into soma

3

Axon:

conducts the impulses away from the soma to the AXON Terminal

4

Synaspe:

connecticion b/w 1 neuron & other cell

5

Postsynaptic cell:

1 axon connecting to an axon terminal

a neuron/myosite/gland

6

Presynaptic cell:

usually a neuron

7

Presynaptic Axon Terminal:

synaptic end of an axon

8

Synaptic Cleft:

the GAP b/w Presynatpic Axon Terminal &Postsynaptic cell

9

Synaptic Vesicles:

small sacs of neurotransmitters located along the Presynaptic axon terminals

10

Neurotransmitter:

chemicals that serve as messengers from the PRE-to-POST synaptic cell

11

Acetyocholine:

MAIN neurotransmitter of the autonomic N.S.

12

Epinephrine & Norepinephrine:

main neurotransmitters of the

13

When signals reach the PREsynaptic Axon Terminal?

the synaptic vesicles release neurotransmitters into the SYNAPTIC CLEFT

14

Postsynaptic Receptor's function:

structure of the POSTsynaptic cell that receives & binds the neurotransmitter
