Nervous System

• What are the two types of main nervous systems in the body?

  Central nervous system, peripheral nervous system
• What is the role of the Central Nervous System (CNS)?

  processes signals from peripheral nervous system
• What is the role of the Peripheral Nervous System (PNS)?

  takes in information and transfers it to the CNS
• How does the PNS take in information from the external environment?

  sensory receptors
• How does the PNS take in information from the internal environment (body)?

  visceral sensory receptors
• What are the components of the CNS?

  Brain, spinal cord
• What is the main role of the brain in the CNS?

  centre of conscious awareness
• What is the main role of the spinal cord in the CNS?

  responsible for reflex behaviours
• What are the components of the PNS?

  Somatic Nervous System, Autonomic Nervous System
• What is the main role of the somatic nervous system in the PNS?


  responsible for conscious movements
• What is the main role of the autonomic nervous system in the PNS?


  responsible for automatic movements
• What does the somatic nervous system control?

  skeletal muscle via commands from the motor cortex
• What does the autonomic nervous system control?

  organs, glands, smooth muscle
• What pathways does the somatic nervous system have?

  Motor and sensory pathways.
• What pathways does the autonomic nervous system have?

  only motor pathways
• What are the components of the Autonomic Nervous System?

  Sympathetic nervous system, parasympathetic nervous system
• What is the sympathetic nervous system responsible for?

  Fight or flight response.
• What is the parasympathetic nervous system responsible for?

  Rest and digest.
