Target- tubules of the kidneys(nephron) Effect-decreases amount of water allowed to pass into urine

hyposecretion- diabetes insipidus- large amounts of urine productions causing thirst,dehydration, and possibly kidney stones. Hypersecretion- small amounts of urine produced resulting in bloating, swelling, infrequent urination & build up of toxins in body.

Hyposecretion-at birth causes dwarfism Hypersecretion-(childhhod) gigantism, (in adults) causes Acromegaly-changes in hands,feet and face

Target- bones and growth plates & promotes effect- growth of bones, organs and tissues

Hyposecretion- delayed labour, limited amounts of milk Hypersecretion- premature labour, milk may spurt out too easily

Target- uterus, mammary glands effect- induces contractions of uterine muscles during birth & causes mammary glands to release milk during nursing.

Target-female-follicles in ovaries, male-seminiferous tubules in testes effect-f.stimulates follicles in ovary to develop. M.stimulate development of seminiferous tubules & maturing of sperm

Hyposecretion-ovary functions may decline-reduced estrogen-stunt sexual development. M.sperm development stunted

Target-thyroid gland effect-stimulates thyroid gland to release thyroxin

Target-ovaries & testies effect- causes ovulation in females. M.stimulates the interstitial cells of testes to produce testosterone

Hyposecretion- decreased thyroxine levels. Hypersecretion- over production of thyroid hormones & calcitonin

Hyposecretion- underdevelopment of sex organs Hypersecretion-early development

Target- adrenal cortex effect-causes the release of hormones involved in stress response

Target-mammary glands effect- stimulates and maintains milk production after childbirth

hyposecretion- inability to deal with stress Hypersecretion-hyperactivity- increased blood glucose levels

Hyposecretion-reduced milk production hypersecretion-excess stimulation of breasts to produce milk

Target- most body cells effect- increase rate of metabolism of the body

Target-bones & blood effect- move calcium from bones to blood

Hyposecretion- hypothyroidism-low metabolic rate=wight gain, cold, slow pulse. Hypersecretion- hyperthyroidism- high metabolism rate, increase heart rate, weight loss, sweating, eyeball protrude

hypo. disorders: Goiter(enlargement of thyroid), cretinisms(stunted growth, mental retardation, lethargy), Myxedema hyper. disorder : Graves disease

hyposecretion-low calcium levels=stunted growth, malformation of teeth, muscle cramping hypersecretion-high calcium levels in blood & urine. Kidney stones back pain

Target- bones effect- moves calcium into bones from blood

hypersecretion-excess calcium in the blood less in bones-could result in weaker bone structure hypersecretion-low blood calcium- problems with clotting

Target-body cells & liver effect-lower blood glucose levels by : 1) causing liver & muscles to convert glucose to glycogen or 2) causes body cells to absorb sugar in order to metabolize it
