Cell communication is the process by which a cell detects and responds to
signals in its environment. Cells communicate through their own language of
chemical signals. Different compounds, such as hormones and neurotransmitters,
act like words and phrases, telling a cell about the environment around it or
communicating messages.
Cellular swelling (or cloudy swelling) may occur due to cellular hypoxia, which
damages the sodium-potassium membrane pump; it is reversible when the cause
is eliminated. Cellular swelling is the first manifestation of almost all forms of
injury to cells.
Cells - except for cancerous ones - cannot reproduce forever. When aging
cells stop dividing, they become "senescent." Scientists believe one factor
that causes senescence is the length of a cell's telomeres, or protective
caps on the end of chromosomes. Every time chromosomes reproduce,
telomeres get shorter. As telomeres dwindle, cell division stops altogether.
Senescent cells do not function the way young cells do, and are believed
