Hormone - chemical messenger
Endocrine Gland - anterior pituitary, pineal, thyroid, parathyroid, adrenal
Endocrine Tissue - they all secretes hormones
Endocrine Cells - target cells - cells that have receptor which bind to certain hormones.
Target Cell - anterior pituitary, pineal, thyroid, parathyroid, adrenal.
Anterior pit - glandular tissue - stimulate or inhibit release of hormone from anterior pituitary
anterior pituitary - stores hormones - made in the hypothalamus
Endocrine Glands
Growth hormone - stimulates growth of all cells + epiphyseal plate
Thyroid stimulating hormone - stimulate thyroid to release hormones
Adrenocorticotropic hormone - stimulates the adrenal cortex to release hormones
Gonadotropins - stimulate gonads to release hormones
prolactin - stimulation of mammery gland - a hormone released from the anterior pituitary gland that stimulates milk production after childbirth
Thyroid Gland - produces thyroid homone
Thyroid hormone - increase metabolic weight (nutrients to energy)
Calcitonin - produced in thyroid - only active in children decrease osteoclast activity
Parathyroid gland - produces parathyroid hormones
Parathyroid hormone - increases blood calcium levels when it detects low blood pressure.
Adrenal Cortex
Zona glomerulosa - secretes hormone called mineraloiarticiods
Zona Fasciculata - maintain blood pressure levels
Zona reticularis - secretes glucocorticoids "stress hormones"

Testes & Ovaries
Testes - secretes testosterone
Ovaries - secrets estrogen & progesterone
