QUIPPER ENDROCRINE Flashcards
Parathyroid glands are derived from the_________________, ______________ glands from the fourth pouch and the __________ glands from the third pouch
embryonic pharyngeal pouches
Endocrine cells of the parathyroid glands are called
principal (chief) cells
the cell releases a molecule into the
interstitial fluid that binds to receptor of a
similar cell or of the same type.
Autocrine signaling
the cell that posses the receptor for a
certain hormone.
Target cell
The target cell is located far away from the
secreting cell.
Endocrine Signaling
are caused by nonfunctioning parathyroid receptors
pseudohypoparathyroidism
cause by nonfunctioning growth hormone receptors
dwarfism
Stimulates release of thyrotropin (TSH)
Thyrotropin-releasing hormone (TRH)
Stimulates the release of both follicle-stimulating hormone (FSH)
and luteinizing hormone (LH)
Gonadotropin-releasing hormone
(GnRH)
Inhibits release of both somatotropin (GH) and TSH
Somatostatin
Stimulates release of GH
Growth hormone-releasing hormone
(GHRH)
Inhibits release of prolactin (PRL)
Dopamine
Stimulates synthesis of pro-opiomelanocortin (POMC) and
release of both β-lipotropic hormone (β-LPH) and corticotropin
(ACTH)
Corticotropin-releasing hormone (CRH)
Increases water permeability of renal
collecting ducts
Vasopressin/antidiuretic
hormone (ADH)
Stimulates contraction of mammary
gland myoepithelial cells and uterine
smooth muscle
Oxytocin
adrenal cortex order of concentric zone from superficial to deep
Zona glomerulus
Zona fasciculata
Zona reticularis
Secrete mineralocorticoids
Zona glomerulosa
mainly Secrete glucocorticoids and small
amount of weak androgens
Zona fasciculata
