Adrenal Gland : Adrenal gland structure-role of the adrenal gland


 What Is Adrenal Gland ?

The adrenal gland is a small, triangular-shaped endocrine gland that sits atop each kidney. These glands produce hormones that help regulate metabolism, immune function, blood sugar, blood pressure, and other vital processes. The adrenal glands are composed of the outer cortex and the inner medulla. The cortex produces hormones including cortisol and aldosterone, while the medulla produces adrenaline and noradrenaline.

These hormones assist control your blood strain, heart charge, sweating and different sports which can be also regulated by using your sympathetic nervous system.

  • Cortex: The cortex is the outer part of your adrenal gland, and it releases corticosteroid and mineralocorticoid hormones. The adrenal cortex additionally stimulates the manufacturing of small quantities of male sex steroid hormones (androgenic steroids).

Endocrine System

What is the role of the adrenal gland?

The adrenal gland is a small, walnut-sized gland which sits on top of the kidneys. It produces a hormone which helps to regulate the body's responses to stress. The adrenal gland is responsible for the production of cortisol, a hormone which helps to promote the storage of energy, and the production of adrenaline, a hormone which helps to increase heart rate and promote the mobilization of glucose from the liver.

  • Adrenaline (epinephrine) and noradrenaline (norepinephrine): These hormones are called the “combat or flight” hormones and are known as catecholamines. Adrenaline and noradrenaline are capable of growing your coronary heart price and force of heart contractions, increasing blood flow to your muscle groups and brain and assisting in glucose metabolism. They also manage the squeezing of your blood vessels (vasoconstriction), which keeps blood strain.

The number one catecholamines are dopamine, adrenaline and noradrenaline. The adrenal medulla, the internal part of your adrenal glands, produces and releases the catecholamines adrenaline and noradrenaline.

  • Steroid hormones: Steroid hormones assist manipulate metabolism, irritation, immune system capabilities, salt and water stability, improvement of sexual traits and the potential to face up to injury and illness. The adrenal cortex, the outer location of your adrenal glands, produce and launch glucocorticoids, mineralocorticoids and adrenal androgens, which are all varieties of steroid hormones.

Symptoms of the adrenal gland in the human body

Symptoms of the adrenal gland in the human body can be quite varied, and can be caused by many different factors.
