Adrenal Gland and disorders
The adrenal gland is one of the Endocrine glands that produce various hormones needed for the body.
The adrenal gland is located on top of the kidney
It is located on the top of both the kidneys as a Cap
It is 4 to 6 cm long and 2 to 3 cms wide
Let's Learn about adrenal gland in detail
Adrenal Glands consist of two sections, mainly adrenal Outer cortex & inner medulla
Adrenal Cortex secretes hormones needed for the regulation of blood pressure and volume.
The hormones also help in nutrients storage, electrolyte balance and regulation of the immune system
The Adrenal Cortex has 3 regions: Zone Glomerulosa, Zone Fasciculata and Zona Reticularis
Adrenal Medulla secrete amine hormones epinephrine and norepinephrine that regulates homeostasis
Let's learn about the different hormones produced by the Adrenal Cortex
Zone Glomerulosa is the superficial region of cortex produces a group of hormones called mineralocorticoids
Aldosterone is one of the major mineralocorticoids
Mineralocorticoids are essential for maintaining body fluids and electrolyte balance
Zona Fasciculata is the middle region of cortex that produces a hormone called glucocorticoids which helps in the breakdown of stored nutrients
The innermost region of cortex in zona Reticularis which produces steroid hormones needed for adolescence
Let's learn about the functions of the adrenal gland
Releasing hormones is the major function of the adrenal gland
Various hormones are secreted into the bloodstream, which is the basic function of the adrenal gland
Apart from the secretion of hormones adrenal gland take care of balancing stress levels
Stress can be physical like injuries, malnutrition or Psychological like having a bad day
Other functions include maintenance of blood sodium and glucose level.
Let's learn about the disorders due to malfunctioning of adrenal glands
Cushing Syndrome also called hypercortisolism is the common disorder of adrenal gland
It occurs due to the high production of hormones called cortisol. Abnormal obesity is the result of this syndrome
Aldosteronism disorder occurs due to hyperactive adrenal glands
This disorder will increase the sodium levels and decrease potassium levels in the blood. This will lead to blood pressure and volume
In Adrenal virilism, people develop characteristics of the opposite sex
In this disorder males imbibe female characters and females imbibe male characters like Voice change
This disorder occurs due to high production of androgen or due to enlargement of the adrenal glands.
Other disorder are pigmentation of skin, decrease resistance to infection, and uncontrollable stress levels
Adrenal gland in an endocrine gland. It is a major organ in producing vivid hormones.
These hormones are needed for the functioning of other organs
Malfunctions of Adrenal gland may result in Cushing Syndrome which causes abnormal obesity
Aldosteronism:- increase in sodium levels, decrease in potassium level resulting in high blood pressure
Adrenal virilism:- imbibes opposite sex characteristics
