Biopsychology

Question 1

How do both sides of the brain communicate

Answer 1

Corpus callosum

Question 2

Vesicles

Answer 2

Contains neurotransmitters

Question 3

Where are neurotransmitters held

Answer 3

Vesicles

Question 4

Excibitation

Answer 4

Allows electrical impulse to follow through

Question 5

Inhibition

Answer 5

Stops electrical impulse

Question 6

Antagonist drug
Depression

Answer 6

Stops neuron from firing

Question 7

Agonist drug

Answer 7

Copies the action of a neurotransmitter and binds to receptor causing the neuron to fire

Question 8

Example of an excitatory neurotransmitter

Answer 8

Glutamate

Question 9

Dopamine

Answer 9

Neurotransmitter associated with feelings of reward and pleasure

Question 10

Hormone responsible for fight or flight

Answer 10

Norepinephrine or noradrenaline
Which increases alertness

Question 11

Sensory neuron

Answer 11

Carries messages from peripheral nervous system (touch) to the brain

Question 12

Relay neuron

Answer 12

Transfers messages from sensory neurons to motor neurons

Question 13

Motor neuron

Answer 13

Carries messages from central nervous system(relay neurons) to effects such as muscles

Question 14

Neuron

Answer 14

Nerve cells

Question 15

Synaptic transmition

Answer 15

How nerve cells communicate

Question 16

Hypothalamus

Answer 16

Send message to glands to release hormones and stops the release of hormones to keep an even balance

Question 17

Adrenal gland

Answer 17

Located above kidneys and produces stress hormones such as Adrenanlin and cortozol

Question 18

What happens in the endocrine

Answer 18

Signal sent from hypothalamus to targeted gland to produce hormone release
Gland secrets hormone
As level of hormone increases the hypothalamus shuts secretion down
Resulting in stable hormone balance

Question 19

2 divisions of peripheral nervous system

Answer 19

Autonomic
Somantic

Question 20

Somantic nervous system

Answer 20

Receives info from our sense and passes to brain, control muscle movement

Question 21

Autonomic nervous system

Answer 21

Responsible for involuntary movements eg breathing
Sympathetic
Parasympathic

Question 22

Sympathetic

Answer 22

Controls involuntary bodily movements and regulars glads such as adrenaline or Fight or flight which
Helps us to deal with emergencies
Dilated pupils and stops digestive system and pumps blood to muscles to give strength

Question 23

Parasympathetic

Answer 23

Restored body back to normal functioning
Rest and digest

Question 24

Summation

Answer 24

Determines weather the cell fires

Question 25

Glands of endocrine

Answer 25

Pituitary Adrenal Ovaries Testes

Question 26

Structure of sensory, relay, motor neurons

Answer 26

Ld sa sd sa sd La

Question 27

Why can neurons only transmit information in one direction at the synapse

Answer 27

Because the vesicles which hood the neurotransmitters are located in the pre synapse and the receptors which receive the neurostrasmitters are located in the post synapse

Question 28

What is a neurotransmitter

Answer 28

A chemical messenger

Question 29

Long tales in a neuron

Answer 29

Axon

Question 30

What do dentrites do

Answer 30

Receive signals (neurontransmitters) from other neurons

Question 31

What do the myelin sheath do

Answer 31

Speed up the transmutation if nerve impulses by allowing electrical impulses to jump through gaps called nodes of ranvier

Question 32

What does peripheral Nervous system do

Answer 32

acts as a communication network, relaying signals between the central nervous system (brain and spinal cord) and the rest of the body
