<P> Connective tissue ( CT ) is one of the four basic types of animal tissue , along with epithelial tissue , muscle tissue , and nervous tissue . It develops from the mesoderm . Connective tissue is found in between other tissues everywhere in the body , including the nervous system . In the central nervous system , the three outer membranes ( the meninges ) that envelop the brain and spinal cord are composed of connective tissue . They support and protect the body . All connective tissue consists of three main components : fibers ( elastic and collagenous fibers ) , ground substance and cells . Not all authorities include blood or lymph as connective tissue because they lack the fiber component . All are immersed in the body water . </P>
