Noradrenergic cells in medulla

Noradrenergic cells in medulla are a group of neurons that produce and release the neurotransmitter norepinephrine. These cells are located in the medulla oblongata, a part of the brainstem that plays a crucial role in the regulation of various autonomic functions.

Structure

The noradrenergic cells in the medulla are primarily found in two distinct clusters: the A1 cell group and the A2 cell group. These cell groups are part of the larger noradrenergic system, which includes several other clusters of noradrenergic neurons located throughout the brain.

Function

The noradrenergic cells in the medulla are involved in the regulation of a variety of physiological processes. These include blood pressure, heart rate, respiration, and pain perception. They achieve this by releasing norepinephrine, which acts on adrenergic receptors in various target tissues.

Clinical significance

Abnormalities in the function of noradrenergic cells in the medulla have been implicated in a number of neurological and psychiatric disorders. These include hypertension, heart failure, chronic pain, and depression.
