psych brain things

Question 1

nervous system - flow chart

Answer 1

central nervous system (CNS) and the peripheral nervous system (PNS)

Question 2

CNS - flow chart

Answer 2

brain –> forbrain, midbrain and hindbrain; and spinal cord

Question 3

PNS - flow chart

Answer 3

somatic nervous system (SNS) –> sensory and motor nerves and autonomic nervous system (ANS) –> sympathetic nervous systen and parasympathetic nervous system

Question 4

Central nervous sytem

Answer 4

Enables the brain to communicate with of the body by conveying messages from the CNS to the PNS and from the PNS to the CNS

Question 5

peripheral nervous system

Answer 5

Communicates info from the body’s organs, glands and muscles to the CNS from both outside and inside world and via motor neurons

Question 6

Autonomic system

Answer 6

responsible for the communication of info between the CNA and the body’s non-skeletal muscle, internal organs and glands, which carry out the basic bodily functions for survival.

Question 7

somatic system

Answer 7

responsible for the voluntary movements of muscles - communicates sensry info to the CNS and motor info from the CNS

Question 8

sympathetic nersous system

Answer 8

Active in a way to prepare us for danger/perception of danger or stress e.g fight, flight or freeze

Question 9

parasympathetic nervous system

Answer 9

Operates in circumstances where it is relatively calm, responsible for day-to-day functions and keep our bodily functions in a state of balance

Question 10

Hindbrain

Answer 10

in the lower section of the brain, Supports bodily functions, The link between the spinal cord and the brian, Important for movement and balance
Includes: brainstem, medulla, pons, cerebellum

Question 11

the medulla

Answer 11

major component of the hindbrain, continues on from the spine, controls breathing, heartbeat and digestion (basic things we don’t really control consciously)

Question 12

the pons

Answer 12

sits above medulla and receives info sent form visual areas to control body actions

Question 13

the cerebellum

Answer 13

Receives info from the pons, Role is to coordinate the sequence of body movement

Question 14

the midbrain

Answer 14

responsible of sleep, motor movement and arousal

Question 15

forebrain

Answer 15

cerebrum, hypothalamus, and thalamus

Question 16

the cerebrum

Answer 16

divided into the left and right cerebral hemispheres (right side controls left, left side controls right)

Question 17

amygdala

Answer 17

central to emtional responses and informing emotional memories

Question 18

hypothalamus

Answer 18

Important for the basic survival actions: sleep, regulation of body temperature, expressions in emotions and the four ‘f’s’

Question 19

thalamus

Answer 19

Communications centre of the brain
Receives info from the ears, eyes, skin and other sensory organs, Determines which of the incoming sensory info is the most important for us to pay attention to

Question 20

the Cerebral cortext

Answer 20

Allows us to undertake a range of tasks, to detect the difference between pieces of info, to understand the meaning of the info and to think in abstract and symbolic ways, enabling creativity in art, writing, debating and the use of metaphor

Question 21

Primary cortices

Answer 21

Process and interprets incoming sensory information

Question 22

primary visual cortext - occipital lobe

Answer 22

recieves visual info from the eyes

Question 23

primary audio cortext - temporal lobe

Answer 23

recieves info from the ears

Question 24

primary somatosensory cortext - parietal lobe

Answer 24

receives info from sensory receptors on the skin

Question 25

frontal lobe

Answer 25

The left frontal lobe is associated with speech, initiating motor function, language, planning, judgement, problem solving, aspects of a person’s personality and regulations of emotions

Question 26

parietal lobe

Answer 26

recieves sensations such as touch, pressure, temperature and pain from the body

Question 27

occipital lobe

Answer 27

Info from the left side of each retina is processed in the left occipital lobe and info from the right side of each retina is processed in the right occipital lobe

Question 28

language - association of frontal lobe

Answer 28

left side coordinates the movement of the lips, tongue and vocal cords for articulation of words. Relies on other parts of the frontal lobe for planning sentences and the muscle movement necessary for speech

Question 29

emotional regulation - association of frontal lobe

Answer 29

emotional responses are caused by the limbic system

Question 30

prefrontal cortext - association of frontal lobe

Answer 30

Involved in making plans and predicting outcomes, helping to regulate emotion and behaviour by anticipating the consequences of our actions and anxiety and brain functions as working memory and the ability to focus our thoughts.
