    en.wikipedia.org/wiki/Development_of_the...

    e. The fetal endocrine system is one of the first systems to develop during prenatal development of a human individual. The endocrine system arises from all three embryonic germ layers. The endocrine glands that produce the steroid hormones, such as the gonads and adrenal cortex, arise from the mesoderm. In contrast, endocrine glands that arise ...

    en.wikipedia.org/wiki/Anterior_pituitary

    A major organ of the endocrine system, the anterior pituitary (also called the adenohypophysis or pars anterior) is the glandular, anterior lobe that together with the posterior lobe (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.

    Rathke's pouch. Sketches in profile of two stages in the development of the human digestive tube. In embryogenesis, Rathke's pouch is an evagination at the roof of the developing mouth in front of the buccopharyngeal membrane. It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system. [1]

  6. Posterior pituitary - Wikipedia

    en.wikipedia.org/wiki/Posterior_pituitary

    The posterior pituitary (or neurohypophysis) is the posterior lobe of the pituitary gland which is part of the endocrine system. The posterior pituitary is not glandular as is the anterior pituitary. Instead, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary, and serve as a site ...

  7. Endocrine system - Wikipedia

    en.wikipedia.org/wiki/Endocrine_system

    The endocrine system[1] is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems.

  8. History of the pineal gland - Wikipedia

    en.wikipedia.org/wiki/History_of_the_pineal_gland

    The history of the pineal gland is an account of the scientific development on the understanding of the pineal gland from the ancient Greeks that led to the discovery of its neuroendocrine properties in the 20th century CE. As an elusive and unique part of the brain, the pineal gland has the longest history among the body organs as a structure ...

  9. Endocrine gland - Wikipedia

    en.wikipedia.org/wiki/Endocrine_gland

    The endocrine system is a network of glands and organs located throughout the body. It’s similar to the nervous system in that it plays a vital role in controlling and regulating many of the body’s functions. Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood.
