sensory,relay, motor

Question 6

what is the sensory neurone

Answer 6

it carrys electrical impulses from the receptors to the CNS

Question 7

what is the relay neurone

Answer 7

it carries electircal impulses from the sensory to the motor

Question 8

what is the motor neurone

Answer 8

it carries electrical impulses from the cns to the effectgors

Question 9

what is the cns

Answer 9

it is made of brain or the spinal cord

Question 10

what are receptors

Answer 10

specialised cells that dectectedd the stimulus

Question 11

what is the stimulus

Answer 11

the change in the enviroment

Question 12

what is the effectors

Answer 12

the muscles that contract and glands that produce hormones

Question 13

where are receptors found

Answer 13

in the five sensory organs

Question 14

what are the five sensory organs

Answer 14

ears,eyes,nose,tongue and skin

Question 15

what is the ear

Answer 15

it contains receptors that detect sound

Question 16

what is the eyes

Answer 16

it contains recpetos that detcect light and colour

Question 17

what is the nose

Answer 17

it contains receptors that detect smell

Question 18

Question 20

Answer 20

reflex and concious

Question 21

what is concious action

Answer 21

requires the use of brain because its voluntery

Question 22

what is reflec action?

Answer 22

automatic response which doesn’t require the heat of the brine, and it is important because it saves you from danger

Question 23

name 4 examples of reflex action

Answer 23

touching hot things, blinking,knee jerks, and saliva

Question 24

what are synapps

Answer 24

the gap between the neurones

Question 25

explain what would happen if your were hovering on a hot candle

Answer 25

The stimulus would be the candle; it would be detected by the skin receptors. The sensory neurones will carry electric impulses from the receptors to the cNS. The relay neurones carry eectrical impulses from the sensory to the motor neuone. the motor neuone carries electrical impulses from the cns to the effectors, which would contract to move the hand
