  1. Classify the following hormones as either amino acid derived or steroid derived (figure 4). Write the phrase steroid

    domain), 3. estrogen (Author: NEUROtiker/ public domain), and 4. melatonin (Author: Cacycle/ public domain)

  2. Fill in the chart. Make sure that your write the complete names of the hormones (No abbreviations). If you are
    referencing to Gonadotropin Releasing Hormone and the two hormones that are stimulated by it, you must
    talk about the male and female separately (one roZ is male and the other is female.
    Releasing
    hormone
    Hormone released
    by the Anterior
    Pituitary Gland
    Target organ(s) of the
    hormone from the
    Anterior Pituitary Gland
    Does the target
    organ produce a
    hormone?
    (Yes or NO)
    If a hormone is release by
    the target organ, name the
    hormone(s).
  3. The pituitary gland is often referred to as the “master endocrine gland”. Based on the videos and your readings, is this
    statement true (YES or NO)? __
    Explain your answer.
  4. Label the following diagram (Figure 7) using the following terms.
    Supraoptic nuclei Inferior hypophyseal artery Ventral nuclei
    Primary capillary plexus Secondary capillary plexus Adenohypophysis
    Hypophyseal vein Neurohypophysis Infundibulum
    Superior hypophyseal artery Paraventricular nuclei

  5. When looking at the anterior pituitary gland and posterior pituitary gland histology, you will notice that they look
    different. Why does the anterior pituitary gland look significantly different from the posterior pituitary gland?
  6. Name the five types of endocrine cells found in the anterior pituitary gland.
