T.H. cytology, ranging from microscopy, cell division and cell cycle control, cell growth and differentiation, to introductory cytogenetics. The cells of the deeper layers are strongly adherent to each other under normal conditions. When epithelium is involved by pathologic condition, the cells loose their cohesiveness so that the deeper cells may be exfoliated along with superficial cell. All cells come from preexisting cells created through the process of cell division. Robert Hooke is considered as the father of cytology. Hooke discovered a multitude of tiny pores that he named "cells". Cytology's roots travel back to 1665, when British botanist Robert Hooke, examining a cross-section of cork, gave the spaces the name "cells," meaning "little rooms" or "cavities."
