Dense Irregular Connective Tissue · Histology

How does dense irregular connective tissue differ from loose (areolar) connective tissue histologically?

  1. It has more ground substance and fewer fibers.
  2. It has more fibers and significantly less ground substance and cells.
  3. It is highly vascularized compared to loose tissue.
  4. It contains primarily Type II collagen instead of the more common Type I collagen.
Show answer and explanation

Correct answer: It has more fibers and significantly less ground substance and cells.

Dense connective tissues are named for their high concentration of fibers. Compared to loose connective tissue, they are less flexible but much stronger, containing fewer cells and a minimal amount of ground substance.
