Which of the following statements is FALSE regarding general characteristics of connective tissue proper? Connective tissue proper is composed of a small amount of matrix and large amount of densely packed cells. The matrix of connective tissue proper is clear and gel-like. Connective tissue proper is vascular and has a nerve supply. Connective tissue proper has no free or apical surface.

Connective tissue proper is composed of a small amount of matrix and large amount of densely packed cells. Correct answer is that it is composed of large amount of matrix with widely scattered cells.

Epithelial tissue draws its blood supply from areolar tissue

Liquid Blood Gel-like Connective tissue proper Semi-solid Cartilage Solid Bone

Explain why the sensation of pain can be felt in cartilage when there is no direct nerve supply.

Pain can be felt or detected in the cartilage due to the inflammation or swelling that occurs around the tissue or traumatized region.

Name the formed elements found in blood.
