PITUITARY GLAND

PITUITARY GLAND

1.      Introduction:- pituitary Gland  ond the hypothalamus act as a unit,

Regulating the activity of most of the other endocrine glands,

2.       SITUATION : it lies in the hypophyseal foss of the sphenoid bone below the hypothalamus.

3.      MEASUREMENTS:

-          Shape-pea,

-          Weight- 500 mg.

4.      BLOOD SUPPLY:-

ARTERIAL BLOOD:- This is supplied by branches from the internal carotid artery

                                           VENOUS BLOOD:- Venous  success b/w the layers of durameter.

            FUNCTIONS OF PITUTARTARY GLAND

1.      Production of growth harmone (GH)

a.      It stimulates grow the & division of body cells

b.      It regulates aspects of methabolism in many organs of liner (Intertwine & pamar)

2.      If regulates & Stimulaates growth hormone releasing harmone (GnRH)

3.      Synthesis  of Thyroid Stimulating hormone (TSH)

4.      Releasing of ACTH (Adrenocticotropic hormone)

5.      Stimulation of Prolactine harmone.

It helps for laclation (moth products)

It acts directly on the breasts immediately after child birth.

6.      It produces the gonadotrophine (Sex hormons)
