Epithelial tissue covers the surfaces of the body and internal organs. It is divided into simple and stratified types. Simple tissues are only one cell thick while stratified tissues have multiple layers. Common epithelial tissues include squamous, columnar, cuboidal, and transitional. Connective tissues provide structure and support. Major types include bone, cartilage, dense tissues, loose tissues, blood, and adipose tissue. Bone tissue makes up the skeleton and cartilage provides flexible padding. Connective tissues contain fibers and ground substance. Muscle tissues allow body movement. There are three main types - skeletal, smooth, and cardiac. Skeletal muscle is voluntarily controlled and attached to bones. Smooth muscle is involuntary and found in organs.
