Spindle

Spindle is a biological term that describes the process that occurs in the cells of multicellular organisms that results in cell division. This process is key to the growth, development and functioning of multicellular animals and plants.

The spindle is a curved structure consisting of two halves that are located on opposite sides of the cell. It consists of two strands of chromatin, which are DNA compacted together with histones. These filaments are located along the spindle, forming a spiral. During the process of cell division, the spindle ensures that the two halves of the cell come together and separate into two new cells.

Each half of the spindle consists of a microtubule fiber called a crossbridge. The cross bridge is several micrometers thick and serves as a support point

The spindle or granulocytes are a collection of red cells (lymphocytes, granulocytes and monocytes) containing the same nucleolus. It plays an important role in the normal functioning of lymphocytes, because. promotes the formation of immature lymphocytes. They also participate in the formation of the active form of T-lymphocytes - T-helpers,
