The Nervous Tissue - Coursework Example The connective tissue generally serves to support and connect the body tissues. It also functions in protecting organs and storage of nutrients. The elements of this tissue are fibres, ground substance, and cells. The loose connective tissues (areolar, adipose and reticular) and dense connective tissue (dense regular and dense irregular) are the two kinds of the mentioned tissue. The bone, cartilage, and blood are specialized connective tissues. Categorized into compact and spongy is the bone tissue. The types of cartilage are hyaline cartilage, fibrocartilage, and elastic cartilage and the blood tissue consists of erythrocytes, thrombocytes, and leucocytes. There are three types of muscle tissues, namely the smooth, skeletal and cardiac muscles. The cells that constitute the smooth muscle are spindle-shaped, lying on the walls of organs and blood vessels. The smooth is an involuntary muscle. Striated and packed in bundles, the skeletal muscle aids in movement because it attaches to bones while the cardiac muscle tissue is located in the heart. It is vital for effective blood-flow, which accounts for the heartbeat. The muscular tissue allows for movement of structures and that of the entire body. It also moves food, waste, and blood through organs and accounts for mechanical digestion.The epithelial tissue is classified into tow, namely the cell shape and layer arrangement. Squamous (flat), cuboidal, columnar and transitional are shapes of the tissue in discussion. Based on cell arrangement, the tissue consists of simple, stratified and pseudostratified columnar epithelium. Simple epithelium consists of a single layer of cells for filtration and absorption while stratified aids in protection from abrasion on the skin. Tissues of the endocrine and exocrine glands form the glandular epithelial tissue. The epithelium functions to cover the surface of the body and lining body cavities. It plays roles in filtering and secretion as well.
