The Nervous system

Question 1

What are the 3 main functions of the nervous system?

Answer 1

Receive, process and coordinate/respond to info

Question 2

What are the 2 main divisions of the nervous system

Answer 2

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

Question 3

What is the central nervous system?

Answer 3

carries messages to the PNS

Question 4

What is the peripheral nervous system?

Answer 4

carries messages to and from the CNS

Question 5

What are the 2 divisions of the CNS

Answer 5

the brain and the spinal cord

Question 6

what is the main function of the brain?

Answer 6

responsible for virtually everything we think,feel and do

Question 7

What is the main function of the spinal cord?

Answer 7

connects brain and the PNS initiates spinal reflexes

Question 8

What are the divisions on the PNS

Answer 8

Automic nervous system and the somatic nervous system

Question 9

What are the 4 functions of the nervous system

Answer 9

1. Info is received from the external environment by our sensory organs
2. info is transported to the brain via nervous system
3. Info is then interpreted by the brain and is either stored or the action will take place
   4.The action is then transported to the body via the nervous system to muscles/tendons then the action will occur

Question 10

What are the main functions of the brain?

Answer 10

responsiblefor basically everything we do such as thinking,feeling doing,problem solving,motor skiils. It is the control centre of the body

Question 11

What is the spinal cord?

Answer 11

Receives sensory info from the body and sends the message to the brain for processing
also receives motor information from the brain and sends it to relevant parts of the body to control muscles etc.

Question 12

What are the main functions of the PNS

Answer 12

carries information to the CNS from the bodies muscle organs,gland and sensory organs. carries information from the CNS to the bodies muscles and glands

Question 13

What are the 2 divisions of the PNS?

Answer 13

the somatic nervous system and the autonomic nervous system

Question 14

What is the main function of the SNS

Answer 14

is a network of nerves that carry a sensory information to the CNS and motor information from the CNS

Question 15

How does the SNS functions use sensory information?

Answer 15

Sensory information is receives at sensory receptors sites in the body and carry along the sensory neutral pathways by sensory neutrons.

Question 16

How does the SNS functions use sensory function

Answer 16

The sensory function of the sns is demonstrated when someone touches your hand. The SNS sends the information about touch from the skin to your brain resulting you feeling the same experience.

Question 17

How does the SNS functions use motor function

Answer 17

the motor function of the sns is demonstrated whenever you voluntarily move a body part. For example when you text,frown,brush your hair, walk up stairs or ride a bike, your somatic nervous system is active

Question 18

What is the main function of the ANS?

Answer 18

the ANS is a network of nerves that carries messages between the CNS and the heart,lungs, and other internal organs and glands. The ANS regulates or controls the functioning of internal organs automatically without you having to consciously think about it.

Question 19

What are the 2 sub divisions of the ANS?

Answer 19

sympathetic NS and the parasympathetic NS

Question 20

What is the Sympathetic nervous system responsible for?

Answer 20

Responsible for increasing the activity of most organs and glands in times of vigorous activity,stress or threat.

Question 21

What is the parasympathetic NS responsible for?

Answer 21

decreasing the activity of most organs and gland and restoring the body functions to its normal state
