what is a cell
basic unit of structure and function

nucleus
controls cell activities
Genes
carry inherited characteristics
Mitosis
most cells reproduce by dividing into two identical cells
stem cells
embryonic cells that can transform in any body’s specialized cells
Pathophysiology
study of how diseases occur
Vacuoles
pouchlike structures found throughout the cytoplasm.

nerve tissue
tissue made up of neurons that controls and coordinates body activities by transmitting messages throughout the body
Protoplasm

Prognosis
a prediction of the probably course and or the expected outcome of the disease
