ADRENERGIC FIBER Meaning and
Definition
-
Adrenergic fiber refers to a specialized type of nerve fiber that releases and transmits the neurotransmitter called norepinephrine (also known as noradrenaline) at synapses. These nerve fibers are part of the sympathetic nervous system, which is responsible for the body's "fight or flight" response.
Adrenergic fibers are found throughout the body and play a crucial role in the regulation of various physiological processes. They are primarily involved in mediating the effects of the sympathetic nervous system on different organs and tissues. Upon activation, adrenergic fibers release norepinephrine into synapses, where it binds to specific receptors known as adrenergic receptors on target cells.
The binding of norepinephrine to adrenergic receptors triggers a series of physiological responses, such as increased heart rate, elevated blood pressure, dilation of airways, and inhibition of digestion. These effects help prepare the body for action in response to a perceived threat or stressor.
Adrenergic fibers are also important in fine-tuning the body's physiological processes under normal conditions. They play a role in the regulation of blood flow, pupil diameter, sweating, and many other functions. Dysfunction of adrenergic fibers can lead to various diseases and conditions, such as hypertension, cardiovascular disorders, and autonomic neuropathy.
In summary, adrenergic fibers are specialized nerve fibers that release norepinephrine, transmitting signals to target cells through adrenergic receptors. They are an essential component of the sympathetic nervous system and are involved in regulating a wide range of physiological functions.

Etymology of ADRENERGIC FIBER
The word "adrenergic" refers to the sympathetic nervous system, which is responsible for the body's "fight or flight" response. It comes from the Greek word "adren", meaning "kidney", and the Latin word "ad", meaning "near" or "to". The term "adrenergic fiber" therefore refers to nerve fibers that release the neurotransmitter adrenaline (also known as epinephrine) at their endings. These fibers are involved in transmitting signals related to the sympathetic nervous system and are found throughout the body.
