The Human Brain : From Neurone to Nervous System

APOPTOSIS

  1. Cell Death occurs by two main processes: necrosis and apoptosis.

  2. Necrosis is the process whereby ischaemia, infection or toxins cause the death of many cells of different types in a particular location.

  3. Apoptosis is a physiological process whereby programmed cell death affects cells individually.

  4. Apoptosis can occur in neurones (especially during embronic development), oligodendrocytes (e.g. in multiple sclerosis) and astrocytes.

  5. Neurones appear to be relatively resistant to apoptosis.
