Pns

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

• Somatic

• Autonomic

• The brain

• The spine

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)

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.

The parasympathetic nervous system:

• 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.

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

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

How does the body prevent damage to the fragile brain and spinal cord?

• the brain is kept floating in the skull so it can absorb impacts

• the brain and spinal cord are enclosed in bone (skull and spinal column) to protect it

• the spinal cord is kept safe by being hidden behind other body organs and muscles

• The brain isn't as protected as the spinal cord

What type of neurons are involved in the PNS?
Select those applicable.

• Sensory neurons: detect signals

• Motor neurons: respond to signals

• Interneurons: transfer messages between neurons

• All of the above

What is the function of the PNS?

• Sends signals to the brain

• Carries information to and from CNS to

• Regulates breathing

• Sends messages to the heart

What organs are involved in the peripheral nervous system (PNS)?

• The brain and the spinal cord

• The senses, organs and muscles

• The heart and lungs

• The kidneys and liver

How are the CNS and PNS related?

• PNS detects and sends signal to CNS. CNS interprets and responds to complete action

• CNS detects and sends signal to PNS. PNS interprets and responds to complete action

• PNS works independently of the CNS

• CNS and PNS are not related

Which part of the Peripheral Nervous System (PNS) is responsible for voluntary muscle movements?

• Somatic Nervous System

• Autonomic Nervous System

• Central Nervous System

• Sympathetic Nervous System
