Flashcards in Neural and Hormonal Systems Deck (10):
1

*Myelin Sheath

Specialized cells that are wrapped around the axon to help transmit message faster

2

*Action Potential

Electro-chemical impulse that travels from the cell body down to the end of the axon

3

*Synapse

Junction between 2 neurons (impulses are transmitted across synapse via neurotransmitters)

4

*Neurotransmitters

Chemical messengers that travel across synapse from one neuron to receptors on the next cell

5

*Endorphins

reduce pain and promote pleasure

6

*Dopamine

affects neurons involved in voluntary movement, reward, learning, memory

7

*Serotonin

affects neurons involved in sleep, appetite, mood

8

*Epinephrine

involved in stress response

9

*Sympathetic nervous systems

increases physiological arousal (flight or fight)

10

*Parasympathetic nervous systems

decreases arousal (Rest and Digest)
