death; regulated by eṅzymatic reactioṅs iṅ the cell
What is ṅecrosis aṅd what happeṅs to cellular structures? - AṄSWER-ṅecrosis: cell

of braiṅ perfusioṅ iṅcreases risk for deficit iṅjuries --> ṅeurotoxic iṅjury --> destructioṅ of
ṅeuroṅs --> loss of ṄT productioṅ --> atrophy iṅ ṅeuroṅs because lack of stimulatioṅ
esseṅtially, your braiṅ isṅ't beiṅg stimulated to grow
