Q

Mark scheme:

A

6 marks = structure, 1 role, 1 function of each
Can be asked specific questions about each part of the nervous system - structure, function (CNS—>ANS) (ANS—>CNS) , difference
Assessed on:
• structure = different sections
• difference between sections = roles/functions

Q

A subdivision of the CNS is the brain.
What are the roles of the brain?

A

• Receives and processes information from the senses (e.g the visual cortex process visual information)
• The centre of conscious awareness
• Responsible for higher mental functions (e.g planning, thinking, language)
• Generates emotion and thoughts
• Initials responses
• Stores memories

Q

A subdivision of the CNS is the spinal cord. What are the roles of the spinal cord?

A

• Sends messages to and from the brain
• Connects nerves to the PNS
• Controls reflex actions (e.g removing a hand when it touches a hot plate)

Q

The spinal cord conducts signals to and from where?

A

The brain

20
Q

The spinal cord connects….to the PNS

A

Nerves

21
Q

What does the spinal cord control?

A

Reflex actions

22
Q

What does CNS stand for?

A

Central nervous system

23
Q

What does PNS stand for?

A

Peripheral nervous system

24
Q

What does ANS stand for?

A

Autonomic nervous system

25
Q

What does SNS stand for?

A

Somatic nervous system

26
Q

What’s the role of the peripheral nervous system?

A

Sends messages to and from the central nervous system via neurons.
(Helps the CNS communicate with the outside world)

27
Q

The PNS sends …. to and from the central nervous system via ….

A

Messages
Neurons

28
Q

PNS - Messages are sent via what? To and from what?

A

Neurons
CNS

29
Q

What is the PNS subdivided into?

A

Autonomic nervous system
Somatic nervous system

30
Q

What’s the role of the ANS?

A

• Responsible for involuntary responses for vital functions (e.g breathing, digestion, heart rate)
• Controls smooth (organs) and cardiac muscles (heart) and glands (salivary glands)
• ANS control centers are in the brain stem

31
Q

A subdivision of the PNS is the autonomic nervous system. What are the roles of the ANS?

• Responsible for …… for …. (e.g breathing, digestion, heart rate)
• Controls ….. (organs) and ….(heart) and ….. (salivary glands)
• ANS …. centers are in the …

A

•involuntarily responses, vital functions
•smooth, cardiac muscles, glands
•control, brain stem

32
Q

The ANS is responsible for what?

A

Involuntary responses for vital functions

33
Q

The ANS controls what?

A

Smooth and cardiac muscles and glands

34
Q

Where are the ANS control centers?

A

Brain stem

35
Q

The autonomic nervous system is broken down into what two things?

A

Sympathetic branch
Parasympathetic branch

36
Q

The sympathetic branch and the parasympathetic branch are part of what?

A

The ANS

37
Q

What does the sympathetic branch responsible for?

A

Fight or flight response

38
Q

What is the parasympathetic branch responsible for?

A

Conserve and restore body energy when relaxed

39
Q

A subdivision of the PNS is the somatic nervous system. What are the the roles of the the SNS?

A

• Responsible for voluntary movements such as walking
• Transmits information from the brain to control skeletal muscles
• SNS carried commands from the motor cortex
• Connects the CNS and the sense and integrates the brain with the outside world

40
Q

The roles of the SNS:
• Responsible for …. movements such as ….
• ….. information from the ….. to control …..
• SNS carried …. from the ….
• Connects the CNS and the … and integrates the …. with the ….

A

•voluntary, walking
•transmits, brain, skeletal muscles
•commands, motor cortex
•senses, brain, outside world

41
Q

The SNS is responsible for what?

A

Voluntary movements such as walking

42
Q

What SNS transmits information from where to where?

A

From the brain to skeletal muscles

43
Q

The SNS Carrie’s commands from where?

A

Motor cortex

44
Q

The SNS connects the CNS with what?

A

Sense and integrates the brain with the outside world

45
Q

Comparing the ANS and the SNS.

A

ANS responsible for involuntary movements WHEREAS the SNS is responsible for voluntary movements.

ANS controls smooth and cardiac muscles and glands WHEREAS the SNS transmits informations the the brain to control skeletal muscles.

The ANS control centers and in the brain stem WHERAS the SNS Carrie’s command from the mirror cortex, and connects the CNS and the senses and inter greater the brain with the outside world.
