Understanding the Human Nervous System

What is the primary function of the Central Nervous System (CNS)?

• To connect the brain to the spinal cord

• To pass messages to and from the brain and connect nerves to the PNS

• To control involuntary body functions

• To enable voluntary movement

Which part of the nervous system is responsible for reflex actions?

• Brain

• Peripheral Nervous System

• Spinal Cord

• Somatic Nervous System

What is the role of the Peripheral Nervous System (PNS)?

• To control conscious awareness

• To connect the CNS to organs, limbs, and skin

• To protect the spinal cord

• To manage reflex actions

Which subdivision of the PNS is responsible for voluntary movement?

• Autonomic Nervous System

• Sympathetic Nervous System

• Somatic Nervous System

• Parasympathetic Nervous System

What does the Autonomic Nervous System control?

• Voluntary body functions

• Involuntary body functions

• Sensory information

• Reflex actions

Which system is activated when faced with a stressful situation?

• Somatic Nervous System

• Parasympathetic Nervous System

• Sympathetic Nervous System

• Central Nervous System

What is the main function of the brain in the nervous system?

• To transmit sensory information

• To control involuntary actions

• To be the centre of all conscious awareness

• To connect the CNS to the PNS

Which part of the nervous system transmits sensory and motor information to and from the spinal cord?

• Autonomic Nervous System

• Somatic Nervous System

• Sympathetic Nervous System

• Parasympathetic Nervous System

What protects the spinal cord?

• Brain

• Spinal column

• Peripheral nerves

• Autonomic Nervous System

Which subdivision of the Autonomic Nervous System is responsible for calming the body after a stressful event?

• Somatic Nervous System

• Sympathetic Nervous System

• Parasympathetic Nervous System

• Central Nervous System
