- - - - is to exert centralized control over the other organs of the body
      - driving the secretion of chemicals called hormones
    - - long, thin, tubular structure made up of nervous tissue, that extends from the medulla oblongata in the brainstem
    - - Landline for the brain to connect and operate the body
    - - Makes nerve clusters to help transmit messages toward the brain
  - - - Consists
        
        Sensory nerves
        
        carries sensory information toward the central nervous system
        
        Motor nerves
        
        transduce signals from the CNS to peripheral neurons of proximal muscle tissue.
    - - that supplies smooth muscle and glands, and thus influences the function of internal organs
- - - - affects almost every organ and cell in the body
  - - - controls the thyroid gland, adrenal gland, ovaries and testicles
    - - secretes hormones T4 and T3 into the bloodstream
    - - release parathyroid hormone, which regulates how much calcium is in the blood
    - - fight-or-flight response
    - - makes enzymes to digest proteins, fats, and carbs in the intestines and produces the hormones insulin and glucagon
    - - produces eggs
    - - produces sperm
  - - - a condition in which the body does not properly process glucose, a simple sugar
        
        due to the lack of insulin or, if the body is producing insulin
    - - parathyroid disease
        
        occurs when the thyroid gland does not produce enough thyroid hormone to meet the body's needs
    - - thyroid gland
        
        starts when the cells in the thyroid begin to change, grow uncontrollably and eventually form a tumor
