WITH COMPLETE SOLUTIONS GRADED A++


TRH --> TSH --> TH


Thyroxine - T4 & Triiodothyronine- T3



Lipid soluble; Negative feedback loop



-Essential for normal growth and neurologic development in the fetus and infant

-Affects metabolic, neurologic, CV and respiratory functioning

-Required for the metabolism and function of blood cells, normal muscle functioning, and the integrity

of skin, nails, and hair

-Body heat production

-Insulin antagonist, GH secretion


Calcitonin


From Thyroid



Water soluble



Stimulated by high CA levels

-Lowers serum CA by opposing bone-reabsorbing effect of PTH, prostaglandins, and calciferols by

,inhibiting osteoclastic activity

-Lowers serum Phos

-May decrease CA and Phos absorption in the GI tract


PTH


From Parathyroid



water soluble



target: bone, kidney



-Increases serum calcium concentration: àstimulates osteoblast proliferation, maturation, and release of

acidic enzymes (cathepsin) which mobilizes CA form the bone

à kidneys: increased reabsorption of CA and decreased reabsorption of Phos and Bicarb

-Decreases serum phosphate concentration

Stimulated by a decreased ICA

-Assist in formation of Vit D, which is needed for CA and Phos reabsorption in the gut

Relationship b/t CA and Phos= inverse


PTHrP


From parathyroid



-Similar to PTH

-Important for endochondral bone formation and bone remodeling, and fetal tooth development


Somatostatin

,From hypothalamus



water soluble



Target: ant pit



Inhibits release of TSH and GH


GHRH --> GH


From Ant Pit



Water soluble



-Regulates metabolic processes related to growth and adaptation to physical and emotional stressors,

muscle growth, increased protein synthesis, increased liver glycogenolysis, increased fat metabolism

-IN the liver induces formation of somatomedins, or insulin-like growth factors that have actions similar

to insulin


GNrH --> FSH


From Ant Pit



Water soluble



Target: Women: Granulosa Cells; Men: Leydig Cells

, Women: Follicle maturation, estrogen production

Men: Spermatogenesis


GNrH --> LH


From Ant Pit



Water soluble



Target: Women: Granulosa Cells; Men: Leydig Cells



Women: ovulation, progesterone production

Men: testicular growth, testosterone production


CRH --> ACTH


From Ant pit



water soluble



Target: adrenal cortex



-Increased steroidogenesis (cortisol and androgenic hormones)

-Synthesis of adrenal proteins contributing to maintenance of the adrenal gland

- Potentiate the effects of catecholamines


Glucocorticoids- Cortisol
