Definition of Adrenoreceptors: Adrenoreceptors, also known as adrenergic receptors, are a class of cell membrane receptors that are sensitive to the hormone adrenaline (also called epinephrine) and other catecholamines. These receptors are involved in various physiological processes and mediate the effects of adrenaline and related compounds throughout the body. Types of Adrenoreceptors: There are two […]
Adrenoleukodystrophy (ALD) Overview Adrenoleukodystrophy (ALD) is a rare and inherited metabolic disorder that affects the nervous system’s white matter and the adrenal glands. Cause ALD is caused by a mutation in the ABCD1 gene, which results in the buildup of very long-chain fatty acids (VLCFAs) in different organs of the body. This accumulation leads to

Adrenogenital Syndrome Adrenogenital Syndrome, also known as congenital adrenal hyperplasia (CAH), is a group of genetic disorders that affect the adrenal glands and lead to abnormal hormone production. Cause Adrenogenital Syndrome is caused by mutations in genes responsible for producing enzymes involved in the production of cortisol, a stress hormone, and aldosterone, a hormone that

Adrenocorticotropic Hormone (ACTH) Adrenocorticotropic Hormone (ACTH) is a hormone secreted by the anterior pituitary gland, a pea-sized structure located at the base of the brain. It plays a crucial role in regulating the body’s response to stress and maintaining proper functioning of the adrenal glands. Function ACTH controls the secretion of cortisol, a vital hormone

Adrenocorticoid An adrenocorticoid refers to any of the hormones produced by the adrenal cortex, which is the outer portion of the adrenal gland. These hormones are important in regulating various physiological functions and are classified into two main categories: glucocorticoids and mineralocorticoids. Glucocorticoids Glucocorticoids are a type of adrenocorticoid hormone that play a crucial role
Adrenergic System or Adrenergic Nervous System (ANS) The Adrenergic System, also known as the Adrenergic Nervous System (ANS), is a part of the autonomic nervous system responsible for regulating various involuntary bodily functions. It primarily uses the neurotransmitter called norepinephrine along with epinephrine (adrenaline) to transmit signals between nerve cells. Function The main function of

Adrenergic Receptors Adrenergic receptors are a class of cell surface receptors that respond to the neurotransmitter adrenaline (epinephrine) and related catecholamines like norepinephrine. These receptors play a critical role in the sympathetic nervous system’s fight-or-flight response by regulating various physiological processes when activated. Types of Adrenergic Receptors There are two main types of adrenergic receptors:

Adrenergic Definition: Adrenergic refers to the nervous system, receptors, or drugs that are associated with or affected by epinephrine (adrenaline) and norepinephrine (noradrenaline). The term is derived from the word “adrenaline,” which is one of the main hormones secreted by the adrenal glands. Adrenergic Nervous System Definition: The adrenergic nervous system is a part of
Adrenarche Definition: Adrenarche refers to the early hormonal changes that occur in the adrenal glands during childhood, marking the onset of adrenal maturation and increased production of androgen hormones. Subtitles: 1. Hormonal Changes Adrenarche is characterized by the initiation of hormonal changes in the adrenal glands. These changes lead to increased production and secretion of
Adrenalectomy Definition: Adrenalectomy is a surgical procedure that involves the removal of one or both adrenal glands. The adrenal glands are small, triangular-shaped organs located on top of the kidneys, and they play a crucial role in hormone production and regulation. Indications: Adrenalectomy may be indicated in several situations, including: Tumors: Removal of adrenal tumors,
