What are chromafin cells?

Chromafin cells are neuroendrine cells contained in the adrenal glands above each of the kidneys. Cells of this type are also located near the wall of the bladder, prostate, liver, carotid arteries and vagus nerves. They release chemicals called catecholamines into the bloodstream for immediate circulation throughout the body. When they are treated with chrome salts, they become dark brown color that is easily visible in microscopic examination. Chrome salts are used to dye cells with color to see. Catecholamines, which are excreted by chromaffin cells, react strongly with chrome Solimi, which changes the entire cell body with a different color.

Chromafin cells are first identifiable in the human body during the fifth week of embryo development. Shortly after the development of the Embryonic, the neural ridge over preaortic ganglia and then on the adrenal Medulla. The sympathetic nervous system may also contain chromafin cells in its ganglia. Epinephrine and Norepinephrine secreted by these cells withThey bind to receptors in the brain and create feelings of well -being, energy and pain relief. Another effect of epinephrine is the adrenaline exchanges, which allows the body to complete physically taxing activities.

It is also known that chromafin cells release a substance called enkefalins that causes feelings of euphoria. The feeling of exercise can generally be attributed to the release of these opiates of similar peptides. They are being, pain or physical exertion, the adrenal chromaphin cells can trigger more of these chemicals. Depending on the degree of stimulation, the amount of catecholamines released into the bloodstream can be significantly increased.

The heart muscle is immediately influenced by the chemicals secreted by these cells. Blood is infected with a heart with much greater force than usual, leading to an increase in freshly oxygenated blood into the body. As the secretion rate slows down, the heart rate will be reduced until a normal rhythm is restored.

The liver system is also strongly influenced by the presence of catecholamines in the bloodstream. It increases the processing of glycogen in the liver and causes an increase in blood sugar. The liver is also invited to accelerate the processing of toxic materials with chromafin cells.
