The document contains two tables listing various endocrine hormones, their sources, targets, and principal actions. Table 16-4 lists pituitary hormones and their target organs. Table 16-5 lists thyroid hormones and parathyroid hormones along with their target tissues and general actions of increasing metabolism or affecting calcium levels and bone tissue.

1. Table 16-4
Hormone Source Target
Growth Hormone (GH) Adenohypophysis General
Prolactin Adenohypophysis Mammary glands
Thyroid-stimulating hormone (TSH) Adenohypophysis Thyroid gland
Adrenocorticotropic (ACTH) Adenohypophysis Adrenal cortex
Follicle-stimulating hormone (FSH) Adenohypophysis Gonads (primary sex organs)
Luteinizing hormone (LH) Adenohypophysis Gonads
Antidiuretic hormone (ADH) Neurohypoiphysis Kidney
Oxytocin (OT) Neurohypoiphysis Uterus and mammary glands
Table 16-5
Triiodothyronine Thyroid gland General
Tetraiodothyronine or thyroxine Thyroid gland General
Calcitonin (CT) Thyroid gland Bone tissue
Parathyroid hormone (PTH) or parathormone Parathyroid glands Bone tissue and kidney

2. Principal Action
growth
milk secretion
development and secretion in thyroid gland
development and secretion in adrenal cortex
development of ovarian follicle development of testis
triggers ovulation
water retention by kidney tubules
uterine contractions; stimulates ejection of milk into mammary ducts
Increases rate of metabolism
Increases rate of metabolism
Increases calcium storage in bone, lowering blood Ca++ levels
Increases calcium removal from storage in bone and produces the active form of vitamin D in the kidneys
