Hit or miss
Some of the following statements are true; the others are false.
Mark each accordingly.
_____ 1. The islets of Langerhans cells make up most of the pancreas.
_____ 2. The endocrine cells of the pancreas are called the islet cells.
_____ 3. The islets contain alpha, beta, and delta cells.
_____ 4. Beta cells produce glucagon.
_____ 5. Glucagon raises blood glucose levels by triggering the breakdown of
glycogen to glucose.
_____ 6. Insulin lowers blood glucose levels by stimulating the release of growth
hormone.
_____ 7. Following endocrine gland stimulation, all hormones are released in a
similar pattern.
_____ 8. When a hormone reaches its target site, it binds to a specific receptor on
the cell membrane or within the cell.
_____ 9. A hormone acts only on a cell that has a receptor specific to that
hormone.
_____ 10. The effects of a particular hormone are the same, regardless of the
target site.
Finish line
This illustration shows the major structures of the endocrine system. Label all of
the components.
Strike out
Some of the following statements are incorrect. Cross out all of the incorrect
statements.
1. The pituitary gland regulates other endocrine glands—and their hormones—
through secretion of trophic hormones.
2. Trophic hormones include corticotropin (which regulates adrenocortical
hormones, TSH (which regulates T4 and T3), and LH (which regulates gonadal
hormones).
3. By increasing trophic hormones, the pituitary gland decreases target gland
hormone levels.
4. The hypothalamus also produces trophic hormones that regulate anterior
pituitary hormones.
5. The ability of blood glucose levels to regulate glucagon and insulin release is
an example of the hypothalamic-pituitarytarget gland axis.
6. Examples of nervous system regulation of hormone release include the
stimulation of the posterior pituitary to secrete ADH and oxytocin.
