Introduction to Endocrinology objectives (phys) Flashcards
(17 cards)
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
