Which of these is not a feature of connective tissue?

A. Avascular (except for cartilage and tendons)
B. Contains matrix
C. The matrix could contain some calcium
D. Does not occur in free surface


Answer is A. Avascular (except for cartilage and tendons) (It is highly vascular)


Rationale: Features of connective tissue include:


1) cells, extracellular, and ground substance
2) Does not occur on free surfaces such as linings, except for the joint cavities which are lined by areolar connective tissue.
3) Except for cartilage, it has a nerve supply.
4) Usually highly vascular, except for cartilage (avascular) and tendons which have a small blood supply
5) Matrix may be fluid, semifluid, gelatinous, fibrous, or calcified. It is usually secreted by the connective tissue cells (except for blood) and adjacent cells, and determines the qualities of the tissue. (hard, rubbery, fluid, etc.)
6) Cells can usually divide
