PP Clues - Endocrine Flashcards
Necrosis
Nonprogrammed cell death
Inflammation
Nucleus destroyed first
Apoptosis
Programmed cell death
No inflammation
Nucleus destroyed last
Pyknosis
Nucleus turns into blobs
Karyohexis
Nucleus fragments
Karyolysis
Nucleus dissolves
Somatotrope
GH
Gonadotrope
LH and FSH
Thyrotrope
TSH
Cortiotrope
ACTH
Lactotrope
Prolactin
Receptors used by protein hormones
Cell membrane receptors
Receptors used by steroid hormones
Nuclear membrane receptors
Steroid Hormones
PET CAD (+ Thyroid) Progesterone Estrogen Testosterone Cortisol Aldosterone Vitamin D
Endocrine
Secretion into blood
Exocrine
Secretion into not blood
Autocrine
Works on itself
Paracrine
Works on its neighbors
Merocrine
Exocytosis - cell is maintained
Apocrine
Apex of cell secreted
Holocrine
Whole cell secreted
Organs that do not require insulin for glucose
BRICKLE Brain RBC Intestines Cardiac, Cornea Kidney Liver Exercising muscle
GnRH
Stimulates FSH and LH
GRH
Stimulates GH
CRH
Stimulates ACTH
TRH
Stimulates TSH
PRH
Stimulates Prolactin
Dopamine
Inhibits Prolactin
Somatostatin
Inhibits GH
Inhibits secretin, motilin, CCK
ADH
Conserves water
Vasoconstricts
Concentrates urine
Oxytocin
Milk production
Birth
GH
IGF-1 release from liver
Growth
Sends somatomedin to growth plates
Gluconeogenesis by proteolysis
TSH
T3 and T4 release from thyroid
LH
Testosterone release from testes
Estrogen and Progesterone from ovary
FSH
Sperm or egg growth
ACTH
Cortisol release from adrenal gland
MSH
Skin pigmentation
Stress Hormones
Immediate = Epinephrine 20 minutes = Glucagon 30 minutes = Insulin and ADH 2-4 hrs = Cortisol 24 hrs = GH
Diabetes Insipidus
Too little ADH
Urinate a lot
Central DI
Brain not making ADH
Nephrogenic DI
Blocked ADH receptor
Can be caused by Lithium or Demecocycline
Water deprivation test
Concentrate urine = Psychogenic
Fail to concentrate urine = DI
DDAVP
Concentrate urine = Central DI
Fail to concentrate urine = Nephrogenic DI
SIADH
Too much ADH
Expanded plasma volume
Pee Na+
Difference between SIADH and DI
DI = dilute urine SIADH = concentrated urine
Psychogenic Polydipsia
Pathologic water drinking
Low plasma osmolarity
Aldosterone
Reabsorbs Na+
Secretes H+ and K+
Neuroblastoma
Adrenal medulla tumor in kids
Dancing eyes and feet
Secretes catecholamines
Pheochromocytoma
Adrenal medulla tumor in adults Pressure Pain Palpitations Perspiration Pallor
Zona Glomerulosa makes
Aldosterone
Zona Fasiculata makes
Cortisol
Zona Reticularis makes
Androgens
Conn’s Syndrome
High aldosterone d/t tumor
Captopril test makes it worse
ANP
Inhibits aldosterone
Dilates renal artery (afferent arteriole)
