The document discusses the main types of tissues in the body. There are four primary tissue types - epithelial, connective, muscle and nerve tissue. Epithelial tissues cover surfaces and glands, and are classified as simple or stratified. Connective tissues are found throughout the body and include fibrous, adipose, cartilage and bone tissues. Muscle tissues contain muscle cells and contract to cause movement. Nerve tissues transmit electrical signals throughout the body.

1. TISSUES Tissues are groups of cells similar in structure and function Epithelial Connective Muscle Nerve Erin Ruthe G4
