  1. What is meant by a negative feedback control mechanism?
    • Basically if the body is low on something, it reacts on the organs to stimulate to make that hormone or what ever.
    • Feedback systems are provide precise monitoring and control of the cellular environment. The most common feedback system, negative feedback, occurs because the rising hormone level negates the initiating change that triggered the release of the hormone.
  2. What is the difference between primary and secondary endocrine disorders? List examples of each.
    • Primary Disorders
    • Malfunction of the hormone gland itself
    • hypothyroidism occurs because not enough T3 and T4 are being secreted from the thyroid gland, even though there is adequate thyroid stimulating hormone (TSH) from the anterior pituitary
    • pancreatic beta cells stop producing insulin
    • Secondary
    • Malfunction of tropic hormone producing gland so the hormone-producing gland produces less or more hormone
    • hypothyroidism secondary to insufficient thyroid stimulating hormone (TSH) from anterior pituitary
    • growth hormone deficiency secondary to insufficient growth hormone releasing hormone (GHRH) from the anterior pituitary
  3. What is the causes, pathophysiology, and manifestations of giagantism?
