An endocrine gland is any organ that secretes chemicals (called hormones) into the blood. The hypothalamus releases several hormones, including corticotropin-releasing hormone, thyrotropin-releasing hormone, growth hormone-releasing hormone, oxytocin, antidiuretic hormone, and a bunch of others. Because many of these hormones regulate the activity of the pituitary gland, which is often called the master regulator of the endocrine system, the hypothalamus is often considered the ultimate regulator of the endocrine system.
Looking from the embryonic development of the pituitary gland secretion of hormones from the anterior pituitary gland is under strict control of the hypothalamic hormones. The hypothalamus releases releasing and inhibiting hormones to the anterior lobe where they stimulate or inhibit hormone secretion. With out these hormones the anterior pituitary couldn't modify its synthesis and secretion of the above hormones so the anterior pituitary gland is the main controller of the endocrine system in the analogy of the hypothalamus being the conductor of the endocrine orchestra. Furthermore argument is the neurosecretory cells, that originated in the hypothalamus, extended down into the posterior pituitary and releases oxytocin(OT) and antidiuretic hormones(ADH).Without the neurosecretory cells these hormones couldn't be produced. Therefore the pituitary gland might be the "Master Gland" but the power behind it is clearly the hypothalamus.
The pituitary gland is the master gland. However, many glands work together. The hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland.
The hypothalamus is sometimes called the master endocrine gland because it controls the section of many hormones by the endocrine system. It does this by causing the posterior pituitary gland to secrete oxitocin and vasopressin (ADH), and by sending releasing hormones to the anterior pituitary gland, causing the release of anterior pituitary hormones. These hormones then cause secretion of hormones from other endocrine glands. The hypothalamus also sends information to the autonomic nervous system (ANS). Outputs from the two parts of the ANS, the sympathetic nervous system and parasympathetic nervous system, can then effect the release of hormones by endocrine glands.
The master of the anterior pituitary gland is the hypothalamus. It secretes releasing and inhibiting hormones that control the release of hormones from the anterior pituitary gland.
The pituitary gland is the most important endocrine gland, and is nicknamed the "master gland."pituitary glandthe pituitary gland, also called the master gland.
The pituitary gland is considered the master gland and secretes hormones that control other glands.
anterior pituitary (lobe)
It is also called the neurohypophysis. ADH and oxytocin are produced in the hypothalamus. These are stored in the posterior pituitary. No hormones are actually produced in the posterior pituitary, they are only stored.
An anterior pituitary is a an alternative name for an adenohypophysis, the anterior lobe of the pituitary gland.
The front lobe of the pituitary gland is called the anterior pituitary or adenohypophysis. It is responsible for producing and releasing various hormones that regulate many physiological processes in the body.
The pituitary gland secretes hGH, TSH, and FSH, along with several other hormones. It is often referred to as the "master gland" because it plays a crucial role in regulating various bodily functions such as growth, metabolism, and reproductive processes.
The anterior pituitary is controlled by the hypothalamus, which releases hormones that stimulate the anterior pituitary to release its own hormones. The anterior pituitary itself is not contained within a particular gland, but is connected to the hypothalamus via the pituitary stalk.
The pituitary gland is often referred to as the master gland of the body because it controls the activity of many other glands by secreting various hormones that regulate bodily functions.
The mechanism of transportation from the hypothalamus to the anterior pituitary gland is through a system of blood vessels called the hypothalamic-pituitary portal system, which connects the two structures. Hormones synthesized in the hypothalamus are released into these blood vessels and then travel to the anterior pituitary gland where they can regulate the secretion of pituitary hormones.
The parts of the pituitary gland are the adenohypophysis (anterior) gland and the neurohypophysis (posterior)
