Connective tissues are the most abundant tissues in the body. They envelop, protect, support, and separate structures as well as bind structures together. Connective tissues also act as a cushion between tissues, provide a pathway for nerves and blood vessels into and out of individual tissues, and more. Most connective tissues have a rich nerve supply and blood supply (except for cartilage which is aneural and avascular, and tendons which have a scanty blood supply). Special connective tissue types include cartilage, osseous (bone), and vascular (blood). The matrixes of these connective tissues differ, with some being fluid (blood), semifluid, gelatinous, fibrous (tendon), or calcified (bone). In cartilage, for example, the matrix is firm but pliable, while in bone, the matrix is considerably harder but not pliable.
