Answer 4

Cerebrum
Cerebellum
Medulla
Hypothalamus
 pituitary gland

Question 5

Cerebrum

Answer 5

Controls conscious thought

Question 6

Cerebellum

Answer 6

Coordination and balance

Question 7

Medulla

Answer 7

Basic body functions

Question 8

Hypothalamus

Answer 8

Chemical control of the body

Question 9

Pituitary gland

Answer 9

Chemical control of the body

Question 10

Focusing

Answer 10

By changing the shape of your lense

Question 11

Iris

Answer 11

Controls the amount of light allowed in

Question 12

Dim light to the eye

Answer 12

Pupil enlarges to let as much light in as possible

Question 13

Bright light to eye

Answer 13

Pupil gets smaller so that the retina is not damaged

Question 14

Steps of focusing

Answer 14

Light intensity
Retina
Sensory neurone
Unconscious part of the brain
Motor neurone to iris
Iris muscles
Response (pupil size)

Question 15

Where are sensory receptors found

Answer 15

Sense organs

Question 16

Sense organs

Answer 16

Eye
Ear
Tongue
Nose 
Skin

Question 17

Sense muscles

Answer 17

Pressure
Temperature
Pain

Question 18

Reflexes: breathing

Answer 18

The reflex takes place

Impulses travel to the unconscious brain

Question 19

neurone

Answer 19

A nerve cell
Cell body + dendrites + an axon
Carry electrical impulses

Question 20

Nerve

Answer 20

Neurones together

Question 21

Synapse

Answer 21

The gap where a neurone end and another begins

Question 22

How synapses work

Answer 22

Electrical nerve impulse cannot cross the gap
Chemical transmitters are released
These diffuse across the gap

Question 23

Human central nervous system (CNS)

Answer 23

Brain+spinal cord, gives rapid response to stimuli

Question 24

Peripheral nervous system

Answer 24

Runs all over the body | Spinal nerves +cranial(brain) nerves

Question 25

CNS steps

Answer 25

``` Stimulus Receptor Coordination Effector Response ```

Question 26

Coordination

Answer 26

Multicellular organisms have nervous and hormonal coordination and central systems

Question 27

Sensory neurone

Answer 27

Carry information from sense organs to the CNS

Question 28

Motor neurones

Answer 28

Carry instructions from the CNS to the effector organs

Question 29

Nerves

Answer 29

Sensory Motor Mixed

Question 30

Reflex actions

Answer 30

Do not involve conscious though

Question 31

Reflex steps

Answer 31

``` Stimulus Receptor Sensory neurone Relay neurone in CNS motor neurone Effector Response ```
