This document summarizes the four main types of tissues in the human body: epithelial tissue, connective tissue, muscular tissue, and nervous tissue. It provides examples of each type of tissue and their subtypes and locations. Epithelial tissues line body surfaces and cavities. Connective tissues bind and support other tissues. Muscular tissues allow for body movement. Nervous tissues conduct and transmit nerve impulses. The document discusses the classification, structure, and functions of each tissue type in detail.
