Nervous system

Question 1

Dendrites

Answer 1

Recieve Input(where neurotransmitters binds)

Question 2

Myelin

Answer 2

Speeds up action potential

Question 3

Cell body

Answer 3

Organelles for normal function

Question 4

Axon

Answer 4

Where action potential travels

Question 5

Termimal

Answer 5

Releases nuerptramdmktters or stimulates muscle

Question 6

Resting/polarized/normal

Answer 6

Na+ outside
k+ inside
Maintained by sodium potassium pump

Question 7

Sodium potassium pump

Answer 7

Uses atp to move na+ outside neuron and k+ inside

Question 8

depolarized

Answer 8

Positive , na+ in k+ out

Question 9

Voltage gated sodium channels

Answer 9

Sense change in charge, sequentially open

Question 10

Recoverh

Answer 10

Sodium potassium pump puts ions to rest. Na+ out k+ I’m

Question 11

Myelin

Answer 11

Insulates cells, lets action potential travel faster

Question 12

Synaptic cleft

Answer 12

Space between 2 neurons, contains vesicles filled with. Uerotrams,otters

Question 13

Calcium

Answer 13

Enters terminal when last na+ channel opens, causes vesicles to move and fuse with cell membrane to release neurotransmitters into cleft

Question 14

Nuerotransmitter

Answer 14

Molecule used as signal between 2 neurons

Question 15

When neurotransmitter binds to a receptor

Answer 15

Generates action potential

Question 16

Neurotoxin

Answer 16

Prevent normal functions of neurons
