  • What are the two components of the CNS?

    Brain and spinal cord
  • What are the three main functions of the nervous system?

    Sensory, Integrative, and Motor functions. 
  • What is the function of the sensory component of the nervous system?

    Receptors detect internal or external stimuli and relays information toward the CNS through afferent (ascending) pathways.
  • What does “afferent” mean in terms of neural pathways?

    It means ascending—information travels from the PNS to the CNS.
  • What is the role of the integrative function in the nervous system?

    Analyzes, stores, and perceives sensory information.
  • What is the function of the motor component of the nervous system?

    Causes muscular contraction or glandular secretion through efferent (descending) pathways.
  • What does “efferent” mean in neural pathways?

    It means exiting—signals travel from the CNS to effectors (muscles or glands).
  • What are the two main structural divisions of the nervous system?

    The Central Nervous System (CNS) and the Peripheral Nervous System (PNS)
  • What is the main function of the CNS?

    Acts as the integrative and control center of the nervous system.
  • What is the main function of the Peripheral Nervous System (PNS)?

    Serves as communication lines between the CNS and the rest of the body.
