10 Facts About Endocrine system

Endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs.

Endocrine system can be contrasted to both exocrine glands, which secrete hormones to the outside of the body, and paracrine signalling between cells over a relatively short distance.

Endocrine system glands have no ducts, are vascular, and commonly have intracellular vacuoles or granules that store their hormones.

The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.

The endocrine system has three sets of endocrine outputs which include the magnocellular system, the parvocellular system, and autonomic intervention.

Fetal endocrine system is one of the first systems to develop during prenatal development.

Reproductive Endocrine system begins development at four to five weeks of gestation with germ cell migration.

Typical mode of cell signalling in the endocrine system is endocrine signaling, that is, using the circulatory system to reach distant target organs.

Diseases of the endocrine system are common, including conditions such as diabetes mellitus, thyroid disease, and obesity.

Neuroendocrine system has been observed in all animals with a nervous system and all vertebrates have a hypothalamus-pituitary axis.
