Question 6

Mark scheme:

Answer 6

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

Autonomic nervous system Somatic nervous system

Question 30

What’s the role of the ANS?

Answer 30

• 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

Question 31

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 …

Answer 31

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

Question 32

Answer 32

Involuntary responses for vital functions

Question 33

The ANS controls what?

Answer 33

Smooth and cardiac muscles and glands

Question 34

Where are the ANS control centers?

Answer 34

Brain stem

Question 35

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

Answer 35

Sympathetic branch Parasympathetic branch

Question 36

Answer 36

The ANS

Question 37

Answer 38

Conserve and restore body energy when relaxed

Question 39

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

Answer 39

• 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

Answer 40

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

Question 41

The SNS is responsible for what?

Answer 41

Voluntary movements such as walking

Question 42

What SNS transmits information from where to where?

Answer 42

From the brain to skeletal muscles

Question 43

The SNS Carrie’s commands from where?

Answer 43

Motor cortex

Question 44

The SNS connects the CNS with what?

Answer 44

Sense and integrates the brain with the outside world

Question 45

Comparing the ANS and the SNS.

Answer 45

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.
