  False
• Molecules secreted by endocrine glands that are inactive until changed by their target cells are _.

  Prehormones
• Neurohormones are secreted by specialized cells of the _.


  Hypothalamus
• Endocrine glands develop from _ tissue. 


  Epithelial
• T/F: Prohormones are modified in the target cells.

  False
• T/F: Steroid and thyroid hormones require carrier proteins to be moved through plasma.

  True
• 2 Steroid hormones binding to their nuclear receptors at 2 half-sites on DNA to initiate transcription is called _.

  Dimerization -> Homodimer
• Thyroid hormone receptors may be found _.

  In the Nucleus
• T/F: Steroid and Thyroid hormones both have a genomic action where they end up turning transcription on or off.

  True
• T/F: Both the steroid and thyroid hormone mechanism of action are identical.

  False
• The regulatory subunit prefers to bind to _ when present in the adenylate cyclase mechanism of action.

  cAMP
• Protein _ reverses the action of protein kinases.

  Phosphatase
• _ destroys cAMP. 


  PDE
• Inositol triphosphate causes _ to diffuse into the cell from the endoplasmic reticulum.

  Calcium
• Which pathway do the Beta 2 receptors use?

  Adenylate Cyclase / cAMP
• Which pathway do the Alpha 1 receptors use?

  Phospholipase C/ Calcium
• Tyrosine kinase receptors have been implicated as a possible cause of _ if they are damaged and can turn on randomly.

  Cancer
• The _ produces and releases growth factors that trigger the embryonic development of the pituitary gland.

  Notochord
• Abnormally high levels of the Anterior Pituitary hormones will cause the target gland to _.

  Hypertrophy
• Evagination of the _ produces the anterior pituitary.

  Stomodeum
• Evagination of the _ produces the posterior pituitary.

  Hypothalamus
• T/F: The posterior pituitary produces two hormones, ADH and Oxytocin.

  False
• _ acts on the adrenal cortex to cause production and release of the corticosteroids.

  ACTH
• What anterior pituitary hormone is responsible for one version of the condition known as dwarfism?

  GH
• Is dwarfism caused by an abundance or shortage of GH?

  Shortage
• _ is a hormone made my the thyroid gland that is derived from Vitamin D.

  Calcitonin
• _ acts on the testes to cause production of testosterone?

  LH
• _ acts on the follicles of thw ovaries and triggers them to produce an egg.

  FSH
• _ acts on the Thyroid gland to cause production and release of the thyroid hormones.

  TSH
• Corticosteroids are produced by the __.

  Adrenal Cortex
• _ acts on the testes and triggers them to produce sperm.

  FSH
• _ causes ovulation.


  LH
• What is the function of Prolactin in females?

  Stimulates milk production in the mammary glands.
• The principle mineralocorticoid is _.

  Aldosterone
• Glucocorticoids cause __ suppression. This makes them excellent anti-inflammatory drugs.

  Immune System
• T/F: The hypothalamus, AP, and target glands control the functions of one another, so there is no "Master Gland".

  True
• High levels of growth hormone would cause which of the following?

  Decrease in GHRH from hypothalamus & the AP becomes less sensitive to GHRH
• What is the precursor molecule for the 3 types of Adrenal Cortex hormones?

  Cholesterol
