|
Exocrine |
Duct glands possess tubes or ducts leading from the gland to a particular part of the body |
|
|
Endocrine |
Ductless glands depend on the blood and lymph to carry their secretions to various affected tissue |
|
|
Hormones |
body's chemical messengers are specialized to act on specific tissues or influence certain processes in the body |
|
|
Anterior pituitary |
ACTH (adrenocorticotropin) TSH (thyroid-stimulating hormone) FSH (follicle-stimulating hormone) HGH (human growth hormone) LH (Luteinizing hormone) Lactogenic hormone (prolactin) |
|
|
Posterior pituitary |
ADH (antidiuretic hormone; vasopressin) Oxytocin

Placenta |
Chorionic gonadotropn Estrogen and progesterone |
|
|
Hyperactive glands |
oversecrete hormones owing to lack or regulation or glandular tumors |
|
|
Pituitary gland |
small gland often called the master gland because the hormones it secretes stimulate or regulate other glands |
|
|
Important endocrine glands |
Pituitary, thyroid, parathyroid, adrenal, and sex glands |
|
|
Hypothalamus |
controls secretions of the pituitary gland, produces neural and chemical signals by releasing hormones or inhibitory hormones |
|
|
Hyperpituitarism |
over production of growth hormone before puberty = giantism after puberty = acromegaly |
|
|
Hypopituitarism |
inadequate stimulation from the hypothalamus or destruction of the pituitary gland can affect blood pressure, reproduction, growth or failure to thrive |
