Introduction to Endocrinology objectives (phys) Flashcards
Define hormone
chemical substance in small quantities fromg lands that travels through circulatory system to elicit physiological response
define endocrine gland
ductless glands - secrete into ECF 00> blood
distringuish among endocrine, neurocrine, neuroendocrine, paracrine, and autocrine
endocrine - circulating fluids neurocrine - nerves to cells, synaptic cleft neuroendocrine - nerves to body fluids paracrine - nearby cells via ECF autocrine - self via ECF
name and anatomically locate all of the major endocrine glands
hypothalamus pituitary anterior & posterior thyroid parathyroid pancreatic islets adrenal glands (medulla and cortex) GI tract kidneys placenta ovaries/testes
hypothalamus secretions?
Releasing hormones: TRE, GnRH, CRH, GHRH, DA (PIH), somatostatin (SS; SRIF)
Oxytocin
vasopressin
anterior pituitary secretions?
GH, TSH, ACTH, PRL, FSH, LH
thyroid secretions
T3, T4, CT
parathyroid secretions
PTH
pancreatic islets secretions
Insulin (I)
glucagon (Gg)
Somatostatin (SS; SRIF)
adrenal medulla secretions
Epi, NE
adrenal cortex secretions
Cortisol
adrenal androstenedione + DHEA
Aldosterone
GI tract glandular secretions
gastrin secretin cholecystokinin (CCK) Gastric inhibitory peptide (GIP) GLPs
kidney glandular secretions
Renin (-angiotensin)
EPO
calcitriol (vit D3)
placenta glandular secretions
chorionic gonadotropin (hCG)
Estrogens
Progesterone
Placental lactogen (hPL)
ovaries & testes secretions
Inhibin Estrogen (E) Progesterone (P) relaxin testosterone (T)
