Anatomy & Physiology Nervous #8


Which portion of the nervous system processes and stores information?


  1. Somatic nervous system
    • Rationale:

      The somatic nervous system is part of the peripheral nervous system. It’s major functions include voluntary movement of the muscles and organs in addition to reflex movements.

  2. Central nervous system
    • Rationale:

      The portion of the nervous system that stores and processes information in the central nervous system. It controls most functions of the body and mind.

  3. Autonomic nervous system
    • Rationale:

      The autonomic nervous system is a control system that acts unconsciously while regulating bodily functions (e.g., digestion, heart rate, respiratory rate, pupillary response, seuxal arousal, and urination). This system primarily controls the fight-or-flight response.

  4. Parasympathetic nervous system
    • Rationale:

      The parasympathetic nervous system is one of the three divisions of the autonomic nervous system. It conserves energy as it increases intestinal and gland activity, relaxes the sphincter muscles in the digestive tract while also slowing the heart rate.


The nervous system (i.e., neurological system) is the most complex system of the body.


Learning Outcomes

The primary branches of the nervous system are the central nervous system and the peripheral nervous system. The central nervous system contains the brain and the spinal cord. Its primary function is to process and store information.
