Hypothalamus Hormones
Releasing Hormones
Stimulate Anterior Pituitary to secrete hormones
(release more)
Hypothalamus Hormones
Inhibiting Hormones
Inhibits Anterior Pituitary secretion of hormones
(release less)
Anterior Pituitary Hormones
Made by cells and secreted by anterior pituitary
Anterior Pituitary Hormone
Human Growth Hormone (gH) or Growth Hormone (GH)
stimulates body growth and releases sugar
Anterior Pituitary Hormone
Prolactin (PRL)
initiate and control milk secretion
Anterior Pituitary Hormone
Adrenocorticotropic Hormone (ACTH)
activites of adrenal gland; release cortisol
Anterior Pituitary Hormone
Melanocyte Stimulating Hormone (MSH)
activities of melanocytes; brain function memory and learning
Anterior Pituitary Hormone
Thyroid Stimulating Hormone (TSH)
influences the growth and activity of thyroid gland
Anterior Pituitary Hormone
Follicle Stimulating Hormone (FSH)
Luteinizing Hormone (LH)
regulate gamete production and hormonal activity of the gonads (ovaries and testes)
Posterior Pituitary Hormones
Made in hypothalamus, stored and released in Posterior Pituitary
Posterior Pituitary Hormone
Oxytocin
Uterine contraction and releases milk from mammary glands
Posterior Pituitary Hormone
Antidiuretic Hormone (ADH)
decreases urine production; water reassertion from kidney
Thyroid Gland
Located in the throat, just inferior to larynx
Produces two major hormones: thyroid hormone and calcitonin
Thyroid Hormone
Thyroxin (T4)- secreted in greater amount (most made) than T3, cells convert T4 to T3
Thyroid Hormone
Triiodothyronine (T3)- more potent made from T4 in body circulation
Thyroxin (T4)
Triiodothyronine (T3)
-Increase oxygen consumption and metabolic rate
-cell growth and development, and cellular respiration
-pattern for secretion control of metabolic hormones
Thyroid Gland
Calcitonin
Decreases serum calcium levels in blood
Parathyroid Gland
Secretes parathyroid hormone
Parathyroid Gland
Parathyroid Hormone (PTH)
raised serum calcium levels in the blood
Adrenal Cortex
Aldosterone- mineralocorticoids- made in Zona glomerulosa
-increases serum sodium levels, thereby increasing water retention
-decrease serum potassium levels
