what is connective tissue?

what is the mesenchmye?
loosely packed cells from which connective tissue, bone cartilage and the lymphatic systems develop

the supportive tissue in an epithelial organ consisting of connective tissues and blood vessels

what is cell differentiation?
when a less specialised cell becomes more specialised
what is proliferation?
cell proliferation is the process that results in an increase of the number of cells
what is morphogenesis?
the shaping of an organism by embryological processes of differentiation of cells, tissues and organs and the development of organ systems
what is pattern formation?
developmental process by which cells in a developing embryo acquire identities that lead to a well ordered spatial patter of cell activities
what is sequential activity?
timing of events
what is reciprocal activity?
one in control then another
what is dynamic activity?
happens quickly
