- Glucocorticoids of the adrenal cortex are made in what zone?
- What cells secrete Ghrelin?
- neurohemal organ
- a stimulates production of platelets
- b salt-retaining hormone which promotes the retention of Na+ by the kidneys. Na+ retention promotes water retention, which promotes a higher blood volume and pressure
- c Zona fasciculata and secondarily the zona reticularis
- d posterior pituitary; storage area where products of neurons are released to the bloodstream
- e X/A cells of the Oxyntic Mucosa, small and large intestine and pancreas.
5 Multiple choice questions
- Tyrosine is hydroxylated to L-Dopa by tyrosine hydroxylase. This is the rate determining step. L-Dopa is decarboxylated to Dopamine by L-amino acid decarboxylase. Dopamine is transported into vesicles where it is hydroxylatd to Norepinephrine by dopamine beta hydroxylase. Norepinephrine is methylated to epinephrine by phentolamine N-methyltransferase (PNMT)
- causes melanocytes to releases melanin (creates a tan)
- the anterior lobe of the pituitary body
- classically tethered; different types transcribed from different genes
5 True/False questions
Gonadotropin releasing hormone (GnRH) → decapeptide hormone stimulates release of LH, FSH. Release is pulsatile
northern blot steps → A control system that acts by secreting hormones directly into the bloodstream, which then travel to other parts of the body to act on effectors (cells, tissues, organs)
How does cortisol impact prolactin? → In the brain and the GI
Corticotrophs → secreted from the adrenal cortex, aids the body during stress by increasing glucose levels and suppressing immune system function
Anti-mullerian Hormone → any of several closely related compounds that are produced by the thyroid gland and are active metabolically; they contain iodine
