Endocrine System

Endocrine System

The Endocrine System is a network of glands and organs located throughout the body. It’s similar to the nervous system in that it plays a vital role in controlling and regulating many of the body’s functions. However, the endocrine system uses chemical messengers, known as hormones, to transmit information and instructions from one set of cells to another.

Function

The endocrine system plays a role in regulating mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes. It influences nearly every cell, organ, and function of our bodies.

Glands of the Endocrine System

The endocrine system is made up of a complex network of glands, which are organs that secrete substances. The glands of the endocrine system are:

• Hypothalamus
• Pituitary Gland
• Thyroid
• Parathyroids
• Adrenal glands
• Pineal body
• Reproductive glands (which include the ovaries and testes)
• Pancreas

Each of these glands secretes a type of hormone into the bloodstream, and these hormones travel to the cells throughout the body.

Disorders of the Endocrine System

Disorders of the endocrine system can result from the oversecretion or undersecretion of hormones or the inability of hormones to function properly. These disorders can range from diabetes, a condition associated with insufficient insulin production, to hyperthyroidism, a condition associated with an overactive thyroid gland.

Treatment

Treatment of endocrine disorders can be complex, as changes in hormone levels can have widespread effects throughout the body. The approach to treatment varies and depends on the specific disorder. Some treatments aim to restore hormone balance, either by replacing deficient hormones or by suppressing the overproduction of hormones.
