Based on the composition, organization of the extracellular matrix, cell types and their functions, the connective tissue is classified into following three major types: 1. Loose Connective Tissue 2. Dense Connective Tissue 3. Specialised Connective Tissue. 1. Loose Connective Tissue: The loose connective tissue is the least specialized connective tissue in the body.

Tissue is a group of similar cells having a common origin that act together in the performance of a particular function. Early during development, the cells of the growing embryo differentiate into three fundamental embryonic tissues called germ layers namely ectoderm, mesoderm and endoderm. These germ layers, in turn, differentiate into different cell types and tissues that are characteristic of [...]
In this article we will discuss about the classification of simple epithelium. 1. Simple Squamous Epithelium (L., squame = scale): Structure: The simple squamous epithelium consists of thin, extremely flattened cells which are closely fitted like the tiles of a floor. Hence it is also called pavement epithelium. Although the cells are of irregular shape, in the surface view they [...]
