Thyroid Stimulating Hormone. This hormone regulates the growth of the thyroid gland and the production of thyroxine hormone.

It controls the production and secretion of milk from the mammary gland.

Luteinizing Hormone. This hormone helps release the ovum from the follicle, form the corpus luteum and produce estrogen and progesterone.

Follicle Stimulating Hormone. This hormone stimulates sperm and egg production.

(i) Follicle Stimulating Hormone (FSH): This hormone stimulates sperm and egg production.
(ii) Luteinizing Hormone (LH): This hormone helps release the ovum from the follicle, form the corpus luteum and produce estrogen and progesterone.
(iii) Prolactin hormone: It controls the production and secretion of milk from the mammary gland.
(iv) Thyroid Stimulating Hormone (TSH): This hormone regulates the growth of the thyroid gland and the production of thyroxine hormone.
(v) Adrenal stimulating hormone (ASH): It regulates the secretion of adrenal cortex.
(vi) Somatotropic hormone (STH) : It regulates body growth.
(vii) Oxytocin hormone: It accelerates uterine muscle contraction during childbirth. Helps in secretion of milk from mammary glands.
(viii) Vasopressin Hormone (ADH): It regulates the amount of water in urine.
(ix) Gonadrotropic hormone (GTH) : It helps in growth of genitals.

The small gland located in the forebrain that controls the functions of other glands in the body is called the pituitary gland. It looks like a pea. Most of the hormones are secreted from the pituitary gland. The hormones of this gland control the secretion of other glands. Hence it is called Granthiraja or Prabhu Granthi or Hypothesis Cerebri. Human pituitary gland weighs 500 mg. The pituitary gland weighs more in females than in males. Each pituitary gland consists of 3 lobes. First part, meddle part and Post part.

Chemical substances secreted from ductless glands are carried through the blood or lymph to distant specific organs of the body and are active, they are called endocrine glands.

The chemical substances secreted from the ducted glands are transported through the ducts to the nearby parts of the body and are active are called exocrine glands. For example – salivary gland, liver gland, pancreas etc.

The cells or groups of cells that secrete the chemical substances necessary for various biological processes in the body are called glands. The glands of the human body are of two types. Exocrine gland and Antakshara gland.
1. Exocrine Glands: The chemical substances secreted from the ducted glands are transported through the ducts to the nearby parts of the body and are active are called exocrine glands. For example – salivary gland, liver gland, pancreas etc.
2. Endocrine glands: Chemical substances secreted from ductless glands are carried through the blood or lymph to distant specific organs of the body and are active, they are called endocrine glands.

Coordination between different organs and systems of the body by chemicals or hormones is called chemical coordination. There are three types of chemical combinations found in the human body. namely-
1. Endocrine Coordination: Hormones secreted from endocrine glands are transported by blood to various cells and coordinate.
2. Paracrine coordination: Chemicals secreted from cells are carried by a fluid to reach other cells and coordinate.
3. Autocrine regulation: Chemicals secreted by the same cell affect the function of that cell.
