Tissue regeneration moves closer to reality with lab-grown bone, muscle, and cartilage
Body Tissue Medically Reviewed. Last updated on 04/01/2025. One step up from cells are tissues. These collections of cells handle specific jobs throughout your body. There are four main types of tissues: epithelial, connective, muscle and nervous. But people commonly use the term “tissue” informally to talk about parts and structures throughout the body, too.

Tissue Membranes A tissue membrane is a thin layer or sheet of cells that covers the outside of the body (for example, skin), the organs (for example, pericardium), internal passageways that lead to the exterior of the body (for example, abdominal mesenteries), and the lining of the moveable joint cavities. There are two basic types of tissue membranes: connective tissue and epithelial ...
An understanding of the various primary tissue types present in the human body is essential for understanding the structure and function of organs which are composed of two or more primary tissue types. This chapter will focus on examining epithelial and connective tissues. Muscle and nervous tissue will be discussed in detail in future chapters.
The Four Types of Tissues Epithelial tissue, also referred to as epithelium, refers to the sheets of cells that cover exterior surfaces of the body, line internal cavities and passageways, and form certain glands. Connective tissue, as its name implies, binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle ...
