Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue. The other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body.There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal.he other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body. There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal.
They also pad certain organs in the body. b.Fibrous Connective Tissue: Dense tissue owing to the large amounts of collagenous tissue. Tendons and ligaments are the two types of structures containg this tissue.Tendons hold muscle to bone. Ligaments hold bone to bone. 1.Cartilage: Collagenous fibers embedded in a rubbery ground-substance called Chondrin, which is a protein-carbohydrate complex..Muscle Tissue: Composed of long contractile cells. The cells are composed of long microfilaments made of the proteins actin and myosin. There are 3 types of muscle tissue: Striated or skeletal, cardiac, and visceral or smooth.
