Question

Which of these is not found in connective tissues?

• A. Hyaluronic acid
• B. Basement membrane
• C. Collagen fibres
• D. Fluid

Answer 1

The correct option is B Basement membrane

• The ground substance of connective tissue is a transparent material with properties of the viscous solution.
• Its principal constituents are large carbohydrate and protein complexes like hyaluronic acid, which is composed of glucuronic acid and amino sugar.
• There are three types of extracellular fibers - collagenous, elastic, and reticular.
• Most abundant are the fibers composed of collagen. The connective tissues do not have a basement membrane.

So, the correct answer is option B.
