Ovary
What is the part that connects the adenohypophysis and Neurohypophysis to the hypothalamus?
Infundibulum
What hormones does the adenohypophysis produce?
Growth hormone
adrenocorticotropic hormone
luteinizing hormone
follicle stimulating hormone
prolactin and thyroid stimulating hormone
What hormones does the Neurohypophysis release?
Oxytocin and antidiuretic hormone
What does growth hormone do
Stimulates mitosis and overall growth of organisms
What is overproduction of growth hormone
Gigantism in children and acromegaly in adults
What is underproduction of growth hormone
Dwarfism
What does adrenocorticotropic hormone do
Stimulates the Zona fasciculata and causes release of glucocorticoids
What is an overproduction and under production of adrenocorticotropic hormone
Cushing’s syndrome (over) And Addison’s disease (under)
What does Leutinizing hormone do
Stimulates ovulation and corpus luteum formation in females stimulates testosterone in males
What hormone is found in the ovaries and testes
LH
What does follicle stimulating hormone do
Stimulates follicle maturation in females and stimulates spermatogenesis formation in males
What organs does follicle stimulating hormone target
Ovaries and testes
What does prolactin do
Targets mammary glands and stimulates milk production
What does elevated levels of prolactin do
Decrease estrogen and testosterone levels
What does thyroid stimulating hormone do
Stimulates thyroid hormone production T3 and T4
What is overproduction and under production of thyroid stimulating hormone
Overproduction hyperthyroidism underproduction hypothyroidism
What does oxytocin do
Targets the uterus causing uterine contractions causes milk ejection
What does antidiuretic hormone do
Targets the kidney tubules Causes less water to be released
What is under production of antidiuretic hormone
Diabetes insipidus
What produces T3 and T4
Follicular cells and Calloid 
What is this and what is produced here
Parafollicular cells and calcitonin is produced 
What is this what is produced here
Colloid and follicular cells and T3 and T4 is produced
What is goiter
Enlarged thyroid gland iodine deficiency
What is Graves’ disease
Auto immune disease, enlarged thyroid gland
What is the antagonist to parathyroid hormone
Calcitonin
What does parathyroid hormone do
Increases calcium levels in blood and stimulates osteoclast activity
What does the Zona glomerulosa produce
Mineralocorticoids like aldosterone
What does the Zona fasciculata produce
Glucocorticoids like cortisol
What does the Zona reticularis produce
Gonadocorticoids
What do each of these layers control
Glomerulosa controls electrolyte levels in blood
Fasciculata promotes gluconeogenesis
Reticularis converts Ganado corticoids into testosterone and estrogen
What is epinephrine and norepinephrine
Triggers our fight or flight
What is overproduction of Epinephrine and norepinephrine
Hypertension
What hormones are produced here
Glucagon (alpha) and insulin (beta)
What does glucagon and insulin do
Glucagon increases blood sugars and insulin decreases blood sugar levels
What is hyperglycemia
Overproduction of glucagon
Identify the slide and the structures
Ovary, follicles and corpus lutea
What does the ovaries produce
Estrogen and progesterone
Identify the slide
Testes
What does activin and inhibin do
Active and stimulates FSH production and inhibin inhibits FSH production
What is this and what is produced here
Interstitial cells and they produce testosterone
What releases melatonin
Pineal gland
What releases thymosin and thymopoietin
Thymus
