MICROANATOMY

Detailed explanation-1: -Desmosomes. Animal cells may also contain junctions called desmosomes, which act like spot welds between adjacent epithelial cells. A desmosome involves a complex of proteins. Some of these proteins extend across the membrane, while others anchor the junction within the cell.

Detailed explanation-2: -The desmosomes provide strong cell-to-cell adhesion and in humans and other vertebrates they are found in tissues exposed to intense mechanical stress. Examples of these tissues are cardiac muscle tissues, bladder tissues, epithelial tissues, and gastrointestinal mucosa.
