biopsychology

Question 1

the nervous system

Answer 1

the central nervous system and the and the peripheral nervous system

Question 2

the central nervous system

Answer 2

spinal cord and brain

Question 3

peripheral nervous systems two main components

Answer 3

somatic nervous system and autonomic nervous system

Question 4

autonomic nervous system

Answer 4

sympathetic nervous system and the parasympathetic nervous system

Question 5

somatic nervous system

Answer 5

stretches throughout nearly every part of your body. The nerves in this system deliver information from your senses to your brain. They also carry commands from your brain to your muscles so you can move around

Question 6

sympathetic nervous system

Answer 6

speeds up your heart rate, good at responding in dangerous or stressful situations ‘fight or flight’

Question 7

parasympathetic nervous system

Answer 7

slows your heart rate, relaxes your body after periods of stress or danger ‘rest and digest’

Question 8

CNS- the brain part

Answer 8

provides conscious awareness and is involved in all psychological processes

Question 9

the brains 4 main lobes

Answer 9

frontal lobe, parietal lobe, temporal lobe and occipital lobe

Question 10

occipital lobe

Answer 10

processes visual information

Question 11

temporal lobe

Answer 11

processes auditory information

Question 12

parietal lobe

Answer 12

integrates information from the different senses and therefore plays an important role in spatial navigation- sensory information

Question 13

frontal lobe

Answer 13

associated with higher-order functions including planing abstract reasoning and logic, voluntary movement, expressive language and for managing higher level executive functions.

Question 14

the brain stem

Answer 14

connects the brain and the spinal cord and controls involuntary processes including our heartbeat, breathing and consciousness

Question 15

CNS-spinal cord part

Answer 15

transfers messages to and from the brain and the rest of the body, also responsible for simple reflex actions that do not involve the brain-taking your hand of a hot stove to prevent getting injured

Question 16

brain plasiticity

Answer 16

refers to the brains ability to change and adapt because of experience

Question 17

electrical impulse

Answer 17

action potential

Question 18

synaptic gap

Answer 18

the gap between the pre-synaptic neuron and post-synaptic neuron

Question 19

synaptic vesicles

Answer 19

located at the end of the neuron (in the axon terminal), they contain chemical messengers known as neurotransmitters

Question 20

what does the peripheral nervous system do

Answer 20

relays messages from the CNS to the rest of the body

Question 21

fight or flight first stage

Answer 21

a person enters a stressful/dangerous situation

Question 22

fight or flight second stage

Answer 22

the amygdala (part of the limbic system) is activated which sends a distress signal to the hypothalamus

Question 23

fight or flight third stage

Answer 23

the hypothalamus activates the sympathomedullary pathway (SAM pathway)- the pathway running to the adrenal and the sympathetic nervous system

Question 24

fight or flight forth stage

Answer 24

the sympathetic nervous system stimulates the adrenal medulla, part of the adrenal gland

Question 25

fight or flight fifth stage

Answer 25

the adrenal medulla secretes the hormones adrenaline and noradrenaline into the blood stream

Question 26

fight or flight sixth stage

Answer 26

adrenaline causes a number of physiological changes to prepare the body for fight or flight
