Hint: Hormones, are also known the chemical messenger or information molecule, are non-nutrient organic compounds secreted in trace amounts by endogenously located endocrine glands of the body, generally released in the bloodstream by endocrine glands and have specific effect on the specific organ called target organ.
Complete answer:
The first hormone was discovered by Secretin (secreted by duodenal mucosa and stimulating the secretion of pancreatic juices).
Hormones secreted from endocrine glands bind to a receptor and transmits messages which causes the target site to take a specific action. As glands are ductless, so hormones directly secreted into the bloodstream. Some of the major endocrine glands are:
> Pituitary gland
> Pineal gland
> Thymus
> Thyroid
> Adrenal glands
> Pancreas
> Testes
> Ovaries
Hormones on the basis of their chemical composition are classified into: Amine hormones; Steroids; and Proteins and peptide hormones
There are many types of hormones that act on different aspects of bodily functions and processes. Some of these include:
> Development and growth
> Metabolism of food items
> Sexual function and reproductive growth and health
> Cognitive function and mood
> Maintenance of body temperature and thirst
Hyperglycemic hormone and hypoglycemic hormone is also secreted from pancreas and contains glucagon and insulin respectively.
Note: Hormones are derived from proteins and play a very vital role in the functioning of different organs. They also help in the mechanisms of the body to support. Some of them are:
Hormones of thyroid: Thyroid gland releases two hormones Triiodothyronine (T3) and Thyroxine (T4), which helps in controlling the metabolism of the body.
Insulin: Released by pancreas, that allows the body to use glucose or sugar from carbohydrates in the food for energy or to store glucose for future use.
Estrogen: It is a female sex hormone released by the ovaries and responsible for reproduction, menstruation and menopause.
Prolactin: Released by the pituitary gland after childbirth for lactation, which enables female to breastfeed. It plays an important role in fertility by inhibiting follicle-stimulating hormone and gonadotropin-releasing hormone.
Testosterone: It is a male sex hormone and plays an important role in the development of male reproductive tissues; testes and prostate.
Serotonin: It is associated with learning and memory, regulating sleep, digestion, regulates mood, some muscular functions etc.
Cortisol: This is produced by the adrenal gland and helps in controlling physical and psychological stress.
