Question 4

What is the spinal cord protected by?

Answer 4

vertebral column

Question 5

The mammalian nervous system consists of two parts

Answer 5

Central Nervous System (CNS)

Peripheral Nervous System (PNS)

Question 6

Whats Central Nervous System (CNS)

Answer 6

consists of the brain and spinal cord, which are the areas of coordination.

Question 7

Whats Peripheral Nervous System (PNS)

Answer 7

comprises nerves and neurones, which coordinate and regulate body functions.

Question 8

What do receptor cells detect?

Answer 8

a change in the environment (stimulus)

Question 8

How do Electrical pulses move?

Answer 8

Electrical impulses travel through the neurones.

Question 9

What does the nervous system help with?

Answer 9

The nervous system helps with the coordination and regulation of body functions.

Question 10

Receptor cells of eyes?

Answer 10

Light receptor

Question 11

The Impulse goes to through the?

Answer 11

Neurons to the CNS

Question 11

Receptor cells of skin

Answer 11

Pressure receptor

Temperature receptor

Question 12

Receptor cells of nose

Answer 12

Smell receptor

Question 12

Receptor cells of tongue

Answer 12

Taste Receptor

Question 13

Stimulus of eye?

Answer 13

Light

Question 14

The receptor cell change the stimulus to what?

Answer 14

into a impulse

Question 14

Stimulus in Skin

Answer 14

Heat

pressure

Question 14

Stimulus of tongue?

Answer 14

Chemical in food

Question 15

Stimulus of Nose

Answer 15

Chemicals in the air

Question 16

what does the CNS (central nervous system) consist of

Answer 16

Brain and Spinal cord

Question 17

what does the PNS (peripheral nervous system) consists of

Answer 17

The nerves outside of the brain and spinal cord

Question 18

Whats the diffrence between CNS and PNS

Answer 18

The Central nervous system is the brain and the spinal cord, the peripheral nervous system is every other part of the nervous system.

Question 19

what is an involuntary action

Answer 19

An action completed without conscious thought

Question 20

Describe the reflex arc

Answer 20

1.) Stimulus detected by a receptor
2.)impulse passed along sensory neurone to relay neurons in the CNS
3.)impulses passed along motor neurone to effector
4.) Effector brings about the response

Question 20

How is an impulse transmitted between two neurones

Answer 20

-THe impulse reaches the end of one neuron
-vesciles release neurotransmitter into the synaptic gap
-the neurotransmitter diffuses across the gap and binds to receptors in the membrane of the next neurone
-A new impulse is triggered in the next neurone

Question 21

What is the purpose of synapses

Answer 21

To ensure that impulses travel in one direction only

Question 21

what is a synapse

Answer 21

A junction between two neurones

Question 22

Reflex action is

Answer 22

automatically and rapidly integrating and coordinating stimuli with the responses of effectors
