Neurons

Question 0

Axon

Answer 0

Transmits information from dendrites to terminal buttons

Question 1

Neuron

Answer 1

Cell in the nervous system. Receives, processes, and transmits information. Approximately 100billion

Question 2

Dendrites

Answer 2

Receiver of information

Question 3

Terminal Button

Answer 3

Sender of information. Contains neurotransmitters

Question 4

Soma

Answer 4

Cell body that contains the nucleus. Housed in the dendrites

Question 5

Myelin Sheath

Answer 5

Protects the axon. Matures in mid twenties. Allows for faster transmission of information

Question 6

Nodes of Ranvier

Answer 6

Gap between different parts of Myelin Sheath

Question 7

Classes of Neurons

Answer 7

Sensory, Motor, and Interneurons

Question 8

Sensory Neuron

Answer 8

Receptors to your central nervous system

Question 9

Motor Neuron

Answer 9

Central nervous system to your muscles

Question 10

Interneurons

Answer 10

Do both

Question 11

Glia Cells

Answer 11

They’re for guiding new neutrons to correct location. Remove dead Neurons. Remove toxins. Form Myelin Sheath

Question 12

Action Potential

Answer 12

Neuron fires - enacts a response. Combination of different inputs arriving at each dendrite. If combined activation is above the threshold the Neuron fires. 70 is rest state. -55 creates action potential

Question 13

Excitatory Input

Answer 13

To fire.

Question 14

Inhibitory Input

Answer 14

To not fire

Question 15

Rest State

Answer 15

70 is the rest state.

Question 16

Depolarisation

Answer 16

Gates open to allow potassium out. Restoring it back to a resting potential

Question 17

Refractory period

Answer 17

When the Neuron is not ready to fire. No stimulation

Question 18

Absolute refractory period

Answer 18

No amount of stimuli will allow fire/action potential

Question 19

Synaptic Transmission

Answer 19

The relay of information between Neurons between the synaptic gap. Uses neurotransmitters

Question 20

Synapse

Answer 20

Gap between Neurons

Question 21

Receptors

Answer 21

Receptors are the holes which receive the input.
