Neural Firing

Question 1

Neural Transmission

Answer 1

Process by which information is being travels through a neuron

Question 2

Electrochemically

Answer 2

Neurons send messages electrochemically, this means that chemicals cause an electrical signal

Question 2

Electrical part happens inside the neuron itself

Question 3

dendrites reciece a chemical called a neurotransmitter

Question 3

chemicals go to a receptor site

Question 3

the receptor site will trigger the axon to let in positively charged sodium ions

Question 3

selectively permeable membrane the cell membrane of the neuron allows certain ions to pass through while preventing or restricting other ions from moving

Question 4

The reaction betwee

Question 5

Threshold

Answer 5

level of stimulation that a cell body (soma) uses to decide whether to tell the axon to create electricity

Question 6

Resting State

Answer 6

There is a difference between the charges outside the cell and inside of the cell (neuron is charged and ready to fire/polarized)

Question 7

Action potential

Answer 7

An action potential is part of the process that occurs during the firing of a neuron

Question 8

all-or-nothing principles

Answer 8

when a neuron fires it is at full strength or not at all, strength of action potential is constant

Question 9

refractory period

Answer 9

period of time during which a cell is incapable of repeating an action potential(recovery time)

Question 10

Neurotransmitters

Answer 10

Chemical messenger that carries, boosts, and balances signals between neurons, or nerve cells and other cells in the body

Question 11

Excitatory neurotransmitters

Answer 11

They excite connecting neurons and cause them to fire, more action potentials are triggered

Question 12

Inhibitory neurotransmitters

Answer 12

Inhibit (Prevent) the next neurons from firing

Question 13

Acetylcholine “movement & Memory”

Answer 13

Principle neurotransmitter involved in thought, learning, and memory. In the body, it is involved in an activating muscle action

Question 14

Serotonin

Answer 14

Connected to feelings of well-being and happiness (regulation of emotion). It regulates the sleep cycle along with melatonin and also regulates intestinal movements.

Question 15

Dopamine

Answer 15

“Pleasure chemical of the brain” released into the pleasure centers of the brain, related to reward and motivation (learning)

Question 16

Norepinephrine “fight or flight”

Answer 16

Associated with response to danger, attention & responding actions in the brain

Question 17

Gaba

Answer 17

Inhibitory transmitter tjhat slows things down, calming the central nervous system “natural tranquilizer”, gaba also contributes to motor and vision control

Question 18

Glutamate

Answer 18

Major exciatory neurotransmitter, involved with most normal operations of the brain including thinking, long-term memory
