Pseudostratified columnar epithelium : single layer, elongated cells

Stratified squamous epithelium : multilayered layers, top cells flattened

Stratified cuboidal epithelium : multilayered , cube shaped cells

Transitional epithelium: many layers of cube shaped cells and elongated cells

Goblet epithelium : unicellular or multicellular.

Connective tissue ---

Areolar: consist of fibroblasts, macrophages, adipocytes, mast cells, plasma cells

Loosely arranged collagen, reticular and elastic fibers an gelatinous ground substance.

Adipose : adipocytes, fibres are reticular and collagen

Closely packed cells with a small amount of gelatinous ground substance.

Hyaline cartilage : chondrocytes, collagen fibers

Limited ground substance, dense and gel matrix.

Elastic cartilage : chondrocytes, elastic fibers

Limited ground substance, flexible but firm gel matrix.
