Different Glands of Endocrine System
Pituitary Gland.
Just beneath our nose we will find a pea size gland that plays an important role in linking the endocrine system and the nervous system, it is the Pituitary Gland. It produce the Growth hormone which promotes the muscle and bone growth and affects general metabolism.it is being controlled by the hypothalamus.
Pineal Gland
It is Located near the center of the brain of the humans, it secretes melatonin at night when dark.this is the reason why we feel Sleepy During the night because this hormone is affected by the amount of light the person is exposed.
Thyroid Gland and Parathyroid Gland
The Thyroid Gland synthesizes the hormones Thyroxine, Triiodothyronine, and Calcitonin which play a major role in the metabolism, maturation and growth of individual. The Parathyroid Gland which produce the Pituitary Gland. elevates Blood-Calcium Levels. Calcitonin and Prathyroid Hormone influence Bone Integrity and Calcium Absorption
Thymus Gland
Its Primary function is to transform the lymphocytes into T-Cell.These are transported into different Lymph glands and they fight infection and disease.
Adrenal Gland
The adrenal Gland consist of two endocrine tissues, these are the : Medullary Region and the surrounding cortex. the Pituitary Gland. secretes epinephrine and norepinephrine in emergency or emotional situations which stimulates the heart and the vascular system. the Cortex secretes the corticosteroids such as cortisone.These suppresses immune system and they are anti Inflammatory.
Pancreas
The Pancreas secretes hormones such as Insulin and Glucagon that regulate the blood sugar level.
Gonads
The Gonads Produce the steroid sex hormones that stimulate reproductive processes, maintain secondary sex characteristic and influence growth. the Testes produce Androgen and testosterone. The Ovaries produce Estrogen, Progesterone and Relaxin.
As the Summary of this you watch the animated video about Endocrine system.
