The pituitary gland of the brain…


By Bec 5SF

The pituitary gland, also known as hypophysis, is an endocrine gland (one set of internal organs involved in the secretion of hormones into the blood.) The pituitary gland is actually the size of a pea and it sits in the small cavity called sella turcica at the bottom base of the brain. Its posterior lobe is connected to the hypothalamus which is a part of the brain through the stalk (infundibulum). This lobe is caused from neural ectoderm while the anterior lobe is caused from oral ectoderm.

Through the portal vein system, the hypothalamus releases hormones which the anterior pituitary lobe receives. The pituitary gland, scientists would call it the master gland but now we discovered that it is regulated by releasing hormones from the hypothalamus. It is attached to the brain with the pituitary or hypophyseal stalk that is connected with the median eminence.

Nowadays, the pituitary gland and the pineal gland are said to be at this present time, not evolving or degenerating, but are actually dormant. Dormant meaning they are not at the moment but could become active again at any time. Both the pituitary gland and the pineal gland are responsible for the latent faculty, that every human has which is called “Clairvoyance”.

The pituitary gland is divided into two sections: the anterior lobe also known as adenohypophysis and the posterior lobe also known as neurohypophysis. The posterior pituitary is a projection of the hypothalamus which lies below the thalamus in the brain. The thalamus is a large mass of gray matter that is situated in the posterior part of the forebrain that sends impulses to the cerebral cortex of the brain. The hypothalamus does not produce its own hormones, just stores and releases the hormones oxytocin and antidiuretic hormone known as ADH.

The pituitary gland helps the body in many ways and helps control the following body processes:

  • Growth
  • Blood pressure
  • Helps in child birth and pregnancy
  • The sex organ functions in men and women
  • Thyroid gland function
  • The conversion of food into energy also known as metabolism
  • Water balance in the body
