Introduction

Tissues are defined as collections of cells and the extracellular substances surrounding them that work together to perform a specific function. The microscopic study of tissues is called histology. There are four main types of tissue: epithelial tissues, connective tissues, muscle tissues, and nervous tissues. Each type of tissue will be introduced in the following four sections. Body structure contain all four types of tissue with epithelial tissues lining surfaces, connective tissues often with structural roles, muscle tissues causing movement, and nervous tissues sending and receiving signals to and from tissues. Therefore, these four tissue types are found together and support and interact with each other. The diagram below shows how body tissues are categorized into different types.

Tissues are organized into four main types: epithelial, connective, muscle, and nervous. Each category of tissues is further broken up into subcategories.
