Location of Point: This is just on the bulging of both the thumb pad and big toe pad. This is used in the following indications.

 

Pituitary is the king of all endocrine glands. It regulates the activity of most of the endocrine glands.

 

Pituitary, an endocrine gland comes under the endocrine system. The endocrine system consists of endocrine glands which are not anatomically related with each other but functionally they are very much inter-dependent. The endocrine glands are termed as ductless gland because the hormones produced by them passes directly into the bloodstream and carried to other regions called target cells or organs, where they alter (activate/stimulate or deactivate/inhibit) the activity of the target cells.

The pituitary gland is a small organ situated immediately below the hypothalamus of the brain. It weighs only about 0.5 gram, but plays a pivotal role in control of endocrine gland function throughout the body. The activity and hormone secretions of other endocrine glands of the body depend on the hormones of the pituitary gland.

Functions of Pituitary:
Pituitary gland is divided basically into two parts: the anterior (front) pituitary called as Adenohypophysis and the posterior (back) pituitary called as Neurohypophysis. Both these parts of the pituitary produce various types of hormones that act on different target cells of the body. The proper functioning of many of these hormones is essential to correct growth, maturation and reproduction of an individual.

Adenohypophysis:
This anterior part of the pituitary releases many important hormones, with functions implied by their names. Growth hormones (GH) are important in control of cartilage growth in long bones. Thyroid stimulating hormone (TSH) stimulates the production of thyroid hormone. Prolactin (lactogenic hormone) triggers the secretion of milk by the breasts (lactation). Adrenocorticotrophic hormone (ACTH) stimulates the production of hormones (corticosteroids and sex hormones) from the outer part of the adrenal glands (adrenal cortex). Follicle stimulating hormone (FSH) stimulates the development of egg follicles in a woman’s ovaries and sperm cells in a man’s testes. Luteinizing hormone (LH) stimulates the rupture of egg follicles in the ovary, and the formation of a corpus luteum in the ovary to produce progesterone during the latter half of a woman’s menstrual cycle. Melanocyte stimulating hormone causes specialized skin cells all over the body, called melanocyte, to produce melanin, the pigment responsible for the colour of skin, hair and eyes. Extra melanin is produced in response to sunlight.

 
Neurohypophysis:
This part of the pituitary gland is responsible for the secretion of two hormones: vasopressin (anti-diuretic hormone – ADH) and oxytocin. ADH increases water reabsorption from the urine by acting on the kidneys, thus making the urine more concentrated. The ultimate effect of this is to dilute the blood. Oxytocin causes contraction of smooth muscle cells in the uterus during childbirth and in the breasts during milk release (the milk release reflex).
