An Overview of the Endocrine System

An Overview of the Endocrine System

INTRODUCTION Endocrinology is a discipline of medicine that focuses on the endocrine system, which regulates your body's hormones. A physician who specialises in the field of endocrinology is known as an endocrinologist. Diabetes, thyroid abnormalities, osteoporosis, growth hormone deficiency, infertility, cholesterol issues, hypertension, obesity, and other endocrine illnesses are all diagnosed and treated by endocrinologists.

Endocrine System ● serves as the body's communication network along with the nervous system. ● It is made up of different endocrine glands and endocrine cells. ● The glands have the ability to create and release hormones, which are unique chemical messengers.

Hormones ● The body's chemical messengers are hormones.

They are referred to as organic chemicals that are secreted into the bloodstream to regulate metabolic and biological processes.

● These hormones play a role in the communication of information between cells and tissues. Small amounts of these chemicals are produced by a number of endocrine (ductless) glands throughout the body.

Endocrine Glands ❖ Hypothalamus - deep inside the cerebrum of the brain, the hypothalamus connects the central nervous system (CNS) and the endocrine system by secreting hormones that cause other endocrine glands to do the same.

❖ Pituitary - sized like a pea and situated in the brain -releases hormones necessary for the body's water balance, growth, and reproduction.

❖ Thyroid -

two lobes in the front of the neck. plays a significant function in regulating metabolism.

❖ Parathyroid -

four glands located close to the thyroid gland . releases hormone to increase blood calcium levels.

❖ Thymus gland - placed behind the sternum in the mediastinum.

- releases a hormone that is important for T lymphocyte maturation during childhood.

❖ Pancreas - situated behind the stomach in the upper retroperitoneum.

- produces digestive enzymes for the breakdown of fats and proteins.

- modulates the glucagon and insulin hormones' production or inhibition.

❖ Adrenal gland -

situated on the upper surface of each kidney.

Epinephrine and norepinephrine, catecholamine hormones, are secreted by the adrenal medulla three steroidal hormones are secreted by the adrenal cortex.

❖ Gonads -

the primary cause of sexual development, puberty, and subsequent reproduction.

Ovaries release eggs. Sperm is produced by the testes.

Conclusion In endocrinology, cells of the endocrine glands and tissues that release hormones are studied together with their biosynthesis, storage, chemistry, and physiological functions.Freiburg Medical Laboratory offers a full variety of tests for endocrine-related diseases like: Type 1 and Type 2 diabetes, Thyroid disorders, Gestational diabetes, Osteoporosis, Obesity, Infertility, Sexual disorders, Growth hormone disorders, Adrenal and Pituitary problems.
