Lacunar cerebral infarction refers to old or new infarctions deep within the brain. When this occurs, lacunas or holes are formed. Depending on the infracted blood vessels, symptoms like limb numbness, dizziness, headache, aphasia and clumsiness may occur. This is due to the small arteries being blocked. Lacunar cerebral infarction may be caused by cerebral arteriosclerosis and hypertension.
cytokinesis. Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.
Daughter Cells in Mitosis. Mitosis is the stage of the cell cycle that involves the division of the cell nucleus and the separation of chromosomes. The division process is not complete until after cytokinesis, when the cytoplasm is divided and two distinct daughter cells are formed. Prior to mitosis, the cell prepares for division by replicating its DNA and increasing its mass and organelle numbers.
