Chemoreceptor

Chemo receptors are specific receptors related to the cell membrane that are capable of being excited by an external chemical stimulus and generating electrical potentials that serve as biological material for the conduction of nerve impulses and muscle contractions.

Chemoreceptors are not receptors. They are classified as free-floating receptors in the sense that they do not form a structure fixed to the cell membrane, but are dissolved in the cytoplasm of the cell and are formed there on the basis of proteins. The animal cell itself has its own system of mechanisms that ensures the operation of these receptors. Their formation may be limited for all or for some cells during the development of the organism. The genetic determination of the activity of free-floating receptors manifests itself in the case of dependence on these structures of the membrane receptor apparatus from the period before puberty. In this case, nutritional deficiency or nutritional exposure can lead to the cessation of the synthesis of receptors specific to a given period of development of this type of development. There are dysfunctions of some organs with known feedback mechanisms between the cerebral and peripheral parts. For example, with insufficient intake of nicotinic acid or its precursors, there is a decrease in the secretion of the anterior lobe of the pituitary gland (and in elderly people, a lack of vitamin PP is the main symptom) and the thyroid hormone - thyroxine. This type of formation of the activity of clinically known diseases due to genetic disorders in both the formation of a system of free-floating and fixed receptors well illustrates the large role of immune system genes and membrane receptors in the relationship between the brain and the periphery.

Chemical exposure to living cells is the main way to fight cancer cells, but the result of this method frightens even the most persistent. Although chemotherapy can indeed kill cancer cells, it also harms healthy cells. A chemical attack on the body has been given the term “toxic effect,” which also causes noticeable changes in the structure and composition of tissues. Research shows that this treatment has serious side effects, including nausea, vomiting, bleeding,
