Anatomy & Physiology Nervous #1

Question

Which system enables an individual’s ability to receive and respond to stimuli from both the external and internal environments?

Answers

  1. Nervous system
    • Rationale:

      The nervous system enables an individual’s ability to receive and respond to stimuli from both the external and internal environments. For example, when someone touches a hot stove a message of heat is sent to the brain where it is processed which, in turn, causes the brain to send a message to the finger’s to remove them from the stove to remove the unpleasant sensation of pain.

  2. Digestive system
    • Rationale:

      The digestive system is made up of the gastrointestinal (GI) tract in addition to the accessory organs of digestion including the gallbladder, liver, and pancreas.

  3. Endocrine system
    • Rationale:

      The endocrine system is a network of glands in your body that make the hormones that assist cell communication to each other. The endocrine glands impact the majority of every cell, function, and organ within the body.

  4. Circulatory system
    • Rationale:

      The circulatory system moves blood throughout the body and is composed of the arteries, capillaries, and veins within the body in addition to the cardiac muscle. This system transports oxygenated blood from the lungs and heart throughout the body by way of the arteries.

Overview

The neurological system (nervous system) is perhaps the most complex of all the systems within the human body.

Explanation

Learning Outcomes

The nervous system controls, coordinates, and enables the majority of bodily function. These bodily functions include automatic and autonomic functions (e.g., pupillary reflexes, sensory perception) in addition to movement and thinking. The nervous system sends to, and receives messages from, all parts of the body.
