Topic 5 DQ 1

Select two of the following discussion questions for your discussion response. Indicate which questions you have chosen using the format displayed in the "Discussion Forum Sample."

  1. As with all disorders, it is essential to determine the root cause of endocrine disorders. What are primary, secondary, and tertiary disorders? Compare the differences among primary, secondary, and tertiary forms of hyposecretion and hypersecretion.
  2. The hypothalamic-pituitary system is the main controlling factor for normal endocrine function. What are some of the common ways for this finely balanced system to become unstable?
  3. Explain how the circadian rhythm is related to cortisol secretion from the adrenal cortex. What factors cause disturbances in this system?

Topic 5 DQ 2

Select two of the following discussion questions for your discussion response. Indicate which questions you have chosen using the format displayed in the "Discussion Forum Sample."

  1. What are the associated complications with altered thyroid functionality?
  2. Adrenal insufficiency can be induced by steroid treatment. What are associated conditions with adrenal insufficiency and how would you prevent the state of adrenal crisis?
  3. The parathyroid glands serve to regulate calcium levels. How does renal insufficiency contribute to altered functionality of the parathyroid glands?

Topic 5 DQ 1
1. As with all disorders, it is essential to determine the root cause of endocrine
disorders. What are primary, secondary, and tertiary disorders? Compare the
differences among primary, secondary, and tertiary forms of hyposecretion and
hypersecretion.
Endocrine disorders; Primary Hyperparathyroidism: Primary hyperparathyroidism results
from a hyperfunction of the parathyroid glands themselves. There is oversecretion of PTH due to
adenoma, hyperplasia or, rarely, carcinoma of the parathyroid glands. Secondary
Hyperparathyroidism; Secondary hyperparathyroidism is the reaction of the parathyroid glands
to a hypocalcemia caused by something other than a parathyroid pathology, e.g. chronic renal
failure. Tertiary Hyperparathyroidism; Tertiary hyperparathyroidism result from hyperplasia of
the parathyroid glands and a loss of response to serum calcium levels. This disorder is most often
seen in patients with chronic renal failure
Forms of hyposecretion; Primary hyposecretion is an endocrine gland that may be
secreting too little hormone because the gland cannot function normally. Examples of primary
hyposecretion include destruction of the adrenal cortex, leading to decreased cortisol secretion,
and dietary deficiency of iodine leading to decreased secretion of thyroid hormones. In contrast
to primary hyposecretion, a gland may be secreting too little hormone because there is not
enough of its tropic hormone. This is termed secondary hyposecretion. There may also occur
(though rarely) a situation called tertiary hyposecretion. In such a case, there is a deficiency of
hormone production from a gland and also a deficiency of the gland’s tropic hormone. However,
in tertiary hyposecretion the tropic hormone–producing gland is functional; instead...
