Question
2. There is evidence that traumatic brain injuries (including concussions) can damage the pituitary. If a patient suffered a particularly severe brain injury that almost completely eliminated the function of the (anterior and posterior) pituitary gland, based on your knowledge of the hypothalamic-pituitary axis, what would the consequences be?
Your answer may include such terms as hormone, trophic hormone, steroid hormone, peptide hormone, amine hormone, hypothalamus, primary pathology, secondary pathology, tertiary pathology, thyroid releasing hormone (TRH), thyroid stimulating hormone (TSH), thyroid gland, thyroid hormone, corticotropin releasing hormone (TRH), adrenocorticotropic hormone (ACTH), adrenal cortex, cortisol, growth hormone releasing hormone, growth hormone, insulin-like growth factors, gonadotropin releasing hormone, follicle stimulating hormone, luteinizing hormone, Sertoli cells, interstitial cells, follicle, androgens, granulosa cells, thecal cells, estrogens, menstrual cycle, ovarian cycle, uterine cycle, menstruation, etc.
Explanation / Answer
The 'Pituitary Gland' is often called the "master gland" as it controls all other endocrine glands of the body.
1. Why is Pituitary gland damaged:-
2. Consequences:-
a) Adrenal insufficiency (ACTH is not adequatety produced by pituitary)
b) Diabetes insipidus (Pituitary not able to make enough ADH) - Frequent urination & extreme thirst.
c) Hyponatremia - Salt water balance is upset.
a) Hypothyroidism - TSH secretion is disturbed - causes weight gain, fatigue, cold intolerance.
b) Hypogonadism (not enough sex hormones) - FSH & LH production decreased. Can result in stop in menstruation in females and sexual dysfunction or development of breasts in male .
c) Growth Hormone Deficiency- In Adults: increased fat, loss of muscle & bone, decreased energy. In Children: growth problems.
