Student Objectives


  • Name the endocrine glands and the hormones
    secreted by each.

  • Explain how a negative feedback mechanism
    works.

  • Explain how the hypothalamus is involved
    in the secretion of hormones from the pos-
    terior pituitary gland and anterior pituitary
    gland.

  • State the functions of oxytocin and antidiuretic
    hormone, and explain the stimulus for secretion
    of each.

  • State the functions of the hormones of the ante-
    rior pituitary gland, and state the stimulus for
    secretion of each.
