What is the difference between the anterior and posterior pituitary?
The main difference between anterior and posterior pituitary gland is that the action of the anterior pituitary gland is regulated through vessels connected to the hypothalamus whereas the action of the posterior pituitary gland is regulated through nerves connected to the hypothalamus.
What is the role of the posterior pituitary?
The primary function of the posterior pituitary is the transmission of hormones originating from neurons located in hypothalamic brain regions such as the supraoptic nucleus (SON) and paraventricular nucleus (PVN) for secretion directly into peripheral circulation.
What is the two types of pituitary gland?
👉 For more insights, check out this resource.
Your pituitary gland is divided into two main sections: the front (anterior) lobe and the back (posterior) lobe. Connecting the hypothalamus and pituitary gland is a stalk of blood vessels and nerves.
What is anterior pituitary?
The anterior pituitary is the central regulator of the endocrine system, coordinating signals from the hypothalamus centrally and endocrine organs peripherally.

Why is the anterior pituitary called the master gland?
Anatomy of the pituitary gland The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands. The gland is attached to the hypothalamus (a part of the brain that affects the pituitary gland) by nerve fibers and blood vessels.
What does anterior pituitary secrete?
The anterior pituitary gland produces six major hormones: (1) prolactin (PRL), (2) growth hormone (GH), (3) adrenocorticotropic hormone (ACTH), (4) luteinizing hormone (LH), (5) follicle-stimulating hormone (FSH), and (6) thyroid-stimulating hormone (TSH) (Table 401e-1).
Which is commonly called anterior pituitary?
The anterior pituitary is also known as the adenohypophysis, meaning “glandular undergrowth”, from the Greek adeno- (“gland”), hypo (“under”), and physis (“growth”).
What is anterior pituitary gland?
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).
Why anterior pituitary is called master gland?
Where is the anterior pituitary?
The pituitary gland is located inferior to the hypothalamus and is connected to the hypothalamus by a stalk. Hormonal secretion by the anterior pituitary is controlled by hypothalamic-releasing hormones that reach their target endocrine tissues in the anterior pituitary via the pituitary stalk.
Is anterior pituitary bigger than posterior?
The anterior pituitary is larger than the posterior pituitary and has no nervous connection to the…
