Connective Tissue As the name implies, connective tissue serves a "connecting" function. It supports and binds other tissues. Unlike epithelial tissue, connective tissue typically has cells scattered throughout an extracellular matrix. Loose Connective Tissue In vertebrates, the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Loose connective tissue is named based on the "weave" and type of its constituent fibers. There are three main types: Collagenous Fibers Collagenous fibers are made of collagen and consist of bundles of fibrils that are coils of collagen molecules. Elastic Fibers Elastic fibers are made of elastin…show more content…
There are three major types of muscle tissue: Cardiac Muscle Cardiac muscle is so named because it is found in the heart. Cells are joined to one another by intercalated discs which allow the synchronization of the heart beat. Cardiac muscle is branched, striated muscle. Skeletal Muscle Skeletal muscle, which is attached to bones by tendons, is associated with the body's voluntary movements. Skeletal muscle is striated muscle. Unlike cardiac muscle, the cells are not branched. Visceral (Smooth) Muscle Visceral muscle, is found in various parts of the body such as the arteries, the bladder, the digestive tract, as well as in many other organs. Visceral muscle is also called smooth muscle because it doesn't have cross striations. Visceral muscle contracts slower than skeletal muscle, but the contraction can be sustained over a longer period of time. Nervous Tissue: Neurons Nerve tissue , nervous tissue the specialized tissue making up the central and peripheral nervous systems, consisting of neurons with their processes, other specialized or supporting cells, and extracellular material. Nervous tissue is responsible for sensing stimuli and transmitting signals to and from different parts of an organism. Neurons are the basic unit of nervous tissue. As we have previously discussed, structure and function are very much intertwined within biology and the
