Adrenergic

Adrenergic is the term used to describe nerve fibers that use norepinephrine (also known as norepinephrine) as a neurotransmitter.

Adrenergic nerve fibers are part of the sympathetic nervous system. They innervate the heart, smooth muscles of blood vessels, bronchi and other organs. When adrenergic nerves are activated, they release norepinephrine, which binds to adrenergic receptors in target cells, causing an increase in heart rate, constriction of blood vessels, and dilation of the bronchi.

The term "adrenergic" is often used in contrast to the term "cholinergic". Cholinergic nerve fibers use acetylcholine as a neurotransmitter and are part of the parasympathetic nervous system. While adrenergic activation typically results in organ excitation, cholinergic activation typically results in organ inhibition.

Adrenergic receptors are receptors that are sensitive to adrenergic neurotransmitters. They are involved in the transmission of nervous excitation in various organs and tissues.

The adrenergic nervous system consists of nerve cells called adrenergic neurons. These cells release the neurotransmitter norepinephrine into the synaptic cleft. It is the main adrenergic mediator.

The main function of the adrenergic nervous system is the regulation of metabolic processes and energy in the body. It ensures the body’s adaptation to changing environmental conditions, enhances its protective reactions, and accelerates metabolic processes.

**Adrenergic** - (from the Latin “adeps” and “adrenaline”), this is a type of fiber in the nervous system that uses adrenaline (norepinephrine) to transmit a signal from one cell to another. Adrenaline is a hormone that is released by the adrenal glands under extreme conditions. Adrenergic receptors are located in all organs of the body. They are found in the myocardium, skeletal muscles, abdominal cavity, blood vessels, lungs, stomach, intestines, kidneys, spleen and other organs.

Some of the most well-known adrenergic receptors include alpha-1 and beta-2 receptors.
