Hypothalamus - it's primary function is homeostasis
What tissue type is in the anterior pituitary gland? - Simple cubodial epithelium
What tissue type is the posterior pituitary gland? - nervous tissue (white tissue)
Endocrine - secrete hormones (chem. Messengers) into bloodstream.
-intracellular effects
Exocrine - secrete hormones (chem. messengers) via ducts/tubules or directly to a
surface.
Ex: sweat
Hormone - - chemical messenger secreted into bloodstream.
- stimulates response in cells of a tissue or organ
Ex: testosterone
Pineal Gland - deals with melatonin
Anterior pituitary - hypothalamus hormones travel to this pituitary to stimulate or inhibit
the release of the pituitary hormones into the bloodstream.
What are the hormones of the Anterior Pituitary? - Follicle Stimulating Hormone
Luteinizing Hormone
Adrenocorticotropic hormone
Thyroid Stimulating hormone
Prolactin hormone
Growth Hormone
What are two gonadotropin hormones that target gonads? - Follicle stimulating hormone
Luteinizing hormone
Follicle Stimulating Hormone - targets menstrual cycle and sperm production
, Luteinizing Hormone - regulation of ovulation, production of testosterone
Adrenocorticotropic Hormone (ACTH) - stimulates production of cortisol
Thyroid Stimulating Hormone (TSH) - stimulates thyroid gland to produce thyroid
hormones.
Prolactin Hormone - targets mammary glands and milk production.
Growth Hormone (GH) - promotes cell and tissue growth
Hypersecretion - produces a large pituitary
Hyposecretion - leads to pituitary dwarfism
Posterior Pituitary - stores hormones made in the hypothalamus
Hormones of he posterior pituitary - Antidiuretic Hormone (ADH)
0xytocin
Antidiuretic Hormone (ADH) - Stimulates water re absorption
Oxytocin - milk ejection
Thyroid secretes three hormones - T3-triiodothyronine
T4- thyroxine
calcitonin
T3 and T4 - Increase basal metabolic rates
Calcitonin - deposition and release of calcium
Thyroid is made up of - Follicle cells
parafollicular cells
colloid cells
Follicles - functional unit of gland
Parafollicular cells - secrete calcitonin
Colloid cells - Storage region for thyroid hormones (TH)
Goiters - enlargement of the thyroid gland caused by insufficient iodine in the diet
