Chromaffin fabric

Chromaffin tissue is tissue formed by chromaffin cells of the adrenal medulla. The adrenal medulla is modified sympathetic ganglia, and chromaffin cells are homologous to postganglionic sympathetic neurons. These cells contain granules that turn brown when exposed to chromates. The release of adrenaline and norepinephrine from granules occurs upon stimulation of preganglionic sympathetic fibers that form synapses on chromaffin cells. See also Neurohormone.

Chromaffin tissue is a tissue that is formed by chromaffin cells located in the adrenal medulla. These cells are modified sympathetic ganglia, and their cells are homologous with postganglionic sympathetic neurons. When the preganglionic sympathetic fibers passing through these cells are excited, adrenaline and norepinephrine are released from their granules. This leads to an increase in the level of catecholamines in the blood and activation of the sympathetic nervous system.

Chromaffin cells have several features that distinguish them from other cells. First, they contain granules containing chromate, which turns brown when exposed to acid. This dye is used to stain chromaffin cells for histological examination. Second, chromaffin cells release catecholamines in response to sympathetic nerve stimulation. This makes it possible to use chromaffin cells to study the mechanisms of regulation of the sympathetic nervous system and its interaction with other systems of the body.

In addition, chromaffin cells can be used in the treatment of various diseases associated with dysfunction of the sympathetic nervous system. For example, in Parkinson's disease, chromaffin cells are used to treat tremors and other movement disorders. Chromaffin cells can also be used to create drugs that can block the release of catecholamines and reduce stress levels in the body.

In general, chromaffin tissue is an important object for study and use in medicine and biology. Its study can help to better understand the work of the sympathetic nervous system, as well as develop new methods of treating various diseases.

Chromaffected fabric

Chromaffic tissue is tissue formed after the action of chromaffin cells on the adrenal medulla, which is a modified sympathetic ganglion associated with nerve cells. They contain brown granules that expand and release large amounts of adrenaline, which increases the heart rate, dilates the bronchi and blood vessels, and reduces the release of hormones. Thus, the brain's response improves a person's endurance by increasing oxygen consumption and energy resources. However, prolonged exposure to stress can lead to a decrease in the efficiency and adaptive capacity of brain and muscle cells, which significantly reduces the pain threshold and can reduce concentration. It is also important to note that if there is excess action
