What is the exact location of pituitary?

What is the exact location of pituitary?

The pituitary gland is small and oval-shaped. It’s located behind your nose, near the underside of your brain. It’s attached to the hypothalamus by a stalklike structure.

What is the anterior pituitary?

The anterior pituitary, also known as adenohypophysis, is a classic endocrine gland in that it is composed of secretory cells of epithelial origin supported by connective tissue rich in blood and lymphatic capillaries.

What are the parts of anterior pituitary?

It consists of 3 parts:

• Pars distalis. The pars distalis is the largest part of the pituitary gland.
• Pars tuberalis. The pars tuberalis is the part of the adenohypophysis which surrounds the anterior aspect of the infundibular stalk.
• Pars intermedia.

What is anterior to the 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).

What is the location and function of pituitary gland?

The Pituitary Gland is at the anatomical and functional crossroads of the brain, mind and body. Weighing less than one gram and measuring a centimeter in width, the pituitary is often called the “master gland” since it regulates the secretion of the body’s hormones.

What is anterior and posterior pituitary?

Anterior pituitary is the anterior glandular lobe of the pituitary, called adenohypophysis. Posterior pituitary is the posterior glandular lobe of the pituitary, called neurohypophysis. The posterior pituitary does not synthesize hormones, it stores and releases vasopressin and oxytocin.

What is the anterior lobe of the pituitary gland?

The anterior lobe makes up about 80% of the pituitary gland. It regulates growth, metabolism, and reproduction through the hormones that it produces. The production of these hormones is either stimulated or inhibited by chemical messages sent from the hypothalamus to the pituitary.

Are there neurons in the anterior pituitary?

Whilst the pituitary gland is known as the master endocrine gland, both of the lobes are under the control of the hypothalamus: the anterior pituitary receives its signals from the parvocellular neurons, and the posterior pituitary receives its signals from magnocellular neurons.

What surrounds the pituitary gland?

The pituitary gland is enveloped by dura and sits within the sella turcica of the sphenoid bone. The sella turcica is a saddle-shaped depression that surrounds the inferior, anterior, and posterior aspects of the pituitary.

How can the anterior part of the pituitary gland control the secretion of thyroid hormones?

The thyroid gland is part of the hypothalamic-pituitary-thyroid axis, and control of thyroid hormone secretion is exerted by classical negative feedback, as depicted in the diagram. Thyroid-releasing hormone (TRH) from the hypothalamus stimulates TSH from the pituitary, which stimulates thyroid hormone release.
