A cell undergoing apoptosis shows a series of characteristic morphological changes. Early alterations include: Cell shrinkage and rounding occur because of the retraction of lamellipodia and the breakdown of the proteinaceous cytoskeleton by caspases. [56] The cytoplasm appears dense, and the organelles appear tightly packed. [citation needed]
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.
Bleb growth is driven by intracellular pressure (abnormal growth) generated in the cytoplasm when the actin cortex undergoes actomyosin contractions. [5] The disruption of the membrane-actin cortex interactions [4] are dependent on the activity of myosin-ATPase [6] Bleb initiation is affected by three main factors: high intracellular pressure, decreased amounts of cortex-membrane linker ...
Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include mutations (which can destroy the gene to build up the organ), poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, excessive amount of apoptosis of cells, and disuse or lack of exercise or disease intrinsic to the tissue itself.
An atrophic factor is a force that causes a cell to die. Only natural forces on the cell are considered to be atrophic factors, whereas, for example, agents of mechanical or chemical abuse or lysis of the cell are considered not to be atrophic factors. Common types of atrophic factors are: [23] Decreased workload; Loss of innervation
Soluble fiber helps keep you full for longer, which can support weight loss. Try replacing a bowl of high-added-sugar cereal with oats, swapping out rice for higher-fiber grains like barley, or ...
