Mechanism of anoxic depolarization in the brain disruption. Other consequential damage that occurs includes lipolysis, proteolysis, cell swelling, microtubule disaggregation, and DNA fragmentation. Neurons are more susceptible to brain ischemia than the supporting glial cells, because neurons have higher energy demand, conduct an action potential, and produce glutamate, whereas glial cells lack those properties. Yet neurons differ among themselves in their sensitivity to ischemia, depending on the specific properties they exhibit, relating to their locations in the brain. "Selective vulnerability" is the term used to describe how some parts of the brain are more sensitive to anoxia than others, and thus to ischemic insult. Anoxia-prone cells in
Development of the human body inconsistent and contradictory; a person may be biologically an adult, and have adult behavior but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may define an adult. Development of human organs and organ systems begins in the embryo and continues throughout the human lifespan. Development of the human body Human development is the process of growth to maturity. The process begins with fertilisation, where an egg released from the ovary of a female is penetrated by a
