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

Pain can be detected in cartilage because of the inflammation that occurs around the tissue.

Which of the following statements is FALSE regarding loose connective tissue? a. Areolar tissue is avascular b. Reticular tissue forms a structural framework called a stroma around soft organs c. Adipose tissue gives shape to the body d. All of the above are true statements

a. Areolar tissue is avascular. Correct answer is that areolar tissue is highly vascular.

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

a. 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.
