Explanation A burn is mainly a tissue damage or cell death, which occurs due to electricity, ultraviolet radiation (UV), chemicals, and intense heat. Burns can be divided into various groups/degrees according to their severity. Sunburn is classified as the first-degree burn. Sunburned skin generally peels in sheets to get rid of the dead cells. Cell junctions present between the cells connects one cell to another and form a mesh...

Chapter 4, Problem 30CAQ

Summary Introduction

To review:

On the basis of types and characteristics of cell junctions, explain the peeling off of sunburned skin in sheets.

Introduction:

A cell junction is a structure present in the tissues, which connect to neighboring cells and the extracellular matrix. These junctions mainly allow communication. Cell junctions are of three types, i.e., desmosomes, tight junctions, and gap junctions. Impermeable junctions surround the cells and connect them together into sheets, which are leak proof.
