Exam 2 Patho Endocrine Flashcards
What are the endocrine glands?
Pituitary, thyroid, adrenal, pancreas
hypothalamus
Coordinating center of the brain
hypothalamic hormones: GHRH
growth-hormone-releasing hormone that specifically stimulates the synthesis and release of growth hormone
hypo. hormones: GHIH
growth hormone-inhibiting hormone is a hormone that regulates the endocrine system
hypo. hormones: TRH
thyroid troponin releasing hormone that controls the release of thyroid-stimulating hormone
hypo. hormones: CRH
corticotropin-releasing hormone that controls the body’s stress response
hypo hormones: GnRH
gonadotropin-releasing hormone that controls the release of other hormones that regulate reproduction
hypo. hormones: PIF
psychological prolactin inhibiter
ant. pit. hormones: TSH
thyroid-stimulating hormone that tells your thyroid how much thyroid hormone it needs to make.
ant. pit. hormones: ACTH
adrenocorticotropic hormone that helps the body respond to stress
ant. pit. hormones: FSH
follicle-stimulating hormone that helps with sexual development and reproduction
ant. pit. hormones: LH
luteinizing hormone that regulates reproductive processes. especially during the menstrual cycle
Prolactin
controls milk production and growth of breast tissue after childbirth
Growth Hormone GH
essential for normal body growth and maturation
Where are the hypothalamic hormones transported to?
Anterior pituitary through portal vessels.
ADH and Oxytocin are produced where?
By nerve cells in the supraoptic and paraventricular in the hypothalamus.
Hypopituitarism
deficiency of pituitary hormone, not receiving O2, hypothalamus not performing as it should
Hyperpituitarism
Overproduction of pituitary hormone. Excess secretion of ACTH. Excess secretion of growth hormone
anterior pituitary disorders
Hypopituitarism, hyperpituitarism
posterior pituitary disorders
Syndrome of inappropriate ADH secretion (SIADH), DI, pituitary tumors
SIADH
results from failure of the negative feedback system that regulates the release and inhibition of ADH
Sheehan Syndrome
unable to produce any breast milk, affects menstrual cycle, egg production, metabolism, atrophy of uterus and breast tissue, and infertility in women. Leads to testicular atrophy, infertility, in men.
hyperprolactinemia
menstrual irregularities, infertility, bone loss, etc
Deficiency of Prolactin
inadequate lactation, infertility, fatigue, low BP, confusion
