Ø Structural Characterisics : The cells of the epithelial tissue lie closely or side by side on a basement membrane. There is no matrix in this tissue. On the basis of cell size, location in the animal body and nature of work, this tissue is of three types, sch as;
1. Squamous Epithelial Tissue
2. Cuboidal Epithelial Tissue
3. Columnar Epithelial Tissue
Ø Squamous Epithelial Tissue: Cells of this tissue are flat like scales; rnucleus is large (Fig- 1)
Ø Example: Wall of the Bowman's capsule of Kindey.
Ø Function: Mainly filtration and covering. ~
Ø Cuboidal Epithelial Tissue: Cells of this tissue are cuboidal, as the length,
breadth and height of the cells are nearly equal (Fig-2).
Ø Example: Collecting tubules of the kidney
Ø Function: Mainly absorption and covering.
