Cytoperforation
The cellular mouth is a special mechanism that allows cells to receive nutrients and oxygen from the environment. It is a special hole in the cell membrane that opens and closes depending on the needs of the cell.
The opening of a cell's mouth depends on several factors, including the concentration of nutrients in the environment, the pressure in the cell and its need for nutrients. When the concentration of nutrients is low, the cell's mouth closes to prevent them from entering the cell. When the concentration of nutrients becomes high, the mouth opens to absorb them. In addition, for convenience of description, 2 terms are used: “Cytoperforation” - the process of opening and closing the cell’s mouth, and “Cytosmorking” or “Cystosmorking” (from English - “citosmoring”) - a signal to cells about the need to open their mouth to absorb oxygen and nutrients substances. This process occurs when the concentration of these substances increases, as well as under the influence of pressure from inside the cell or mechanical influence from the outside. Cytosmorking is an important signaling mechanism that is used by cells to regulate their vital functions and adapt to changing environmental conditions, such as changes in temperature, light or humidity. Cytosampling is one of the processes in the regulation of the physiological functions of the cell membrane. This is a regulated cellular response that occurs when
