Year 10 Psychology - PNS & CNS (2)

What is the main function of the Central Nervous System (CNS)

• Communication system between the brain and the Peripheral Nervous System (PNS)

• Communication system between muscle and the Peripheral Nervous System (PNS)

• Communication system between the heart and the Peripheral Nervous System (PNS)

• Communication system between the spine and the Peripheral Nervous System (PNS)

What is the main function of the Peripheral Nervous System (PNS)?

• Communicate information from the body’s organs, glands and muscles to the CNS

• Communicate information from the body’s organs, glands and muscles to the CNS and vice versa

• Communicate information to the body’s organs, glands and muscles to the CNS

• Communication between sensory neurons and motor neurons

Two subdivisions off the Peripheral Nervous System (PNS) are?

• The brain and the spinal cord

• Sympathetic nervous system and Parasympathetic nervous system

• Sensory neurons and Motor neurons

• Somatic Nervous System and Autonomic Nervous System

The somatic nervous system is:

• Responsible for INVOLUNTARY MOVEMENT and relays information from the environment to the CNS and relays information from the environment to the CNS so the brain is able to make decisions about behaviour.

• Responsible for INVOLUNTARY muscle stimulation which includes the stimulation of our organs such as heart, digestive tract and glands.

• Responsible for VOLUNTARY MOVEMENT and relays information from the environment to the CNS and relays information from the environment to the CNS so the brain is able to make decisions about behaviour.

• Responsible for VOLUNTARY muscle stimulation which includes the stimulation of our organs such as heart, digestive tract and glands.

The autonomic nervous system is:

• Responsible for INVOLUNTARY muscle stimulation which includes the stimulation of our organs such as heart, digestive tract and glands.

• Responsible for VOLUNTARY MOVEMENT and relays information from the environment to the CNS so the brain is able to make decisions about behaviour.

• Responsible for VOLUNTARY muscle stimulation which includes the stimulation of our organs such as heart, digestive tract and glands.

• Responsible for INVOLUNTARY MOVEMENT and relays information from the environment to the CNS so the brain is able to make decisions about behaviour.

Which of the following parts of the Peripheral Nervous system (PNS) contain the parasympathetic and sympathetic nervous system?

• Somatic

• Autonomic

• The brain

• The spine

The sympathetic nervous system:

• Is our emergency nervous system that helps us calm down after a fright

• Calms us back down and reverts the body back to normal functioning or homeostasis

• Is our emergency NS when we perceive that we are in danger or in times of stress. It initiates the fight, flight or freeze response.

• Is our emergency NS when we perceive that we are in danger or in times of stress and reverts the body back to normal functioning or homeostasis

• Calms us back down after it initiates the fight, flight or freeze response.
