important points
The posterior pituitary does not produce its own hormones. rather, hornones are stored here(oxytocin and vasopressin) .they are produced by the hypothalamus.
pituitary function is assessed by the target gland function, not by measuring the pituitary hormone as an isolated event. This is in contrast to target gland function being assessed by the pituitary hormone
kallmans syndrome is isolated decrease in GnRH + anosmia
in pregnancy pituitary gland is enlarged. when postpartum hge happens this leads to ischemic pituitary necrosis.SHEEHAN’S SYNDROME
revision
Adrenocorticotropic hormone, as its name implies, stimulates the adrenal cortex. More specifically, it stimulates secretion of glucocorticoids such as cortisol, and has little control over secretion of aldosterone, the other major steroid hormone from the adrenal cortex.
i always forget this!!!!!!
rememberrrrr!!!
low blood glucose stimulates production of growth hormones!!! hence insulin stimulation test causes increase GH IN NORMAL PPL AND GH IS NOT ELEVATED IN THIS CASE!! in hypopituitarism that iss…
extras
ACTH is produced in a process that also generates several other hormones
The major attributes of the hormones other than ACTH that are produced in this process are summarized as follows:
Lipotropin: Originally described as having weak lipolytic effects, its major importance is as the precursor to beta-endorphin.
Beta-endorphin and Met-enkephalin: Opioid peptides with pain-alleviation and euphoric effects.(SUBHANALLAH.ALLAH CREATED INNER PAIN RELIEVERS FOR US HUMANS! syukurillah)
Melanocyte-stimulating hormone (MSH): Known to control melanin pigmentation in the skin of most vertebrates.(take note!!!!! in absence of acth, this process is diminished thus DEPIGMENTATION OCCURS IN ARESS NORMALLY PIGMENTED eg; areola)
psssst: kontot notes. will be updated in the future. OSCE ALARM: 3 MORE DAYS IM RUNNING OUT OF TIME STOP PROCRASTINATING.
