sensory, relay and motor neurones

Question 1

how do the neurones transmit signals

Answer 1

electrically and chemically

Question 2

the neurones job

Answer 2

to provide NS with primary means of communication

Question 3

when at resting state and activated

Answer 3

resting state - inside of cell is -vely charged
activated by a stimulus - the inside is =vely charged for a split second (creates an electrical impulse that travels down the axon to the end of the neuron)

Question 4

sensory neurone

Answer 4

• tells brain about internal and external environment
• processes info taken from one of 5 senses
• carries messages from PNS to CNS
• long dendrites, short axons

Question 5

motor neurone

Answer 5

• carry signals from CNS to help organs
• includes glands and muscles to function
• short dendrites, long axons

Question 6

relay neurone

Answer 6

• carry messages from one part pf CNS to another
• connects sensory and motor neurones
• short dendrites, short axons
