Endocrine gland. Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.
37.6]lu contains endocrine cells that secrete prolactin, growth hormone, and several trophic hormones that stimulate other endocrine glands (see Table 37.2). -Hypothalamus secretes releasing and release-inhibiting hormones that control the anterior lobe of the pituitary. Hypothalamus links nervous and endocrine systems. - Hypothalamic neurons secrete hormones that regulate the release of hormones from the anterior lobe of the pituitary gland. Pituitary hormones, in turn, control activity of other endocrine glands.
