The type of connective tissue present in the arrow-marked area is:
Show Hint
The deep reticular dermis has thick collagen bundles running in all directions.

- Loose and irregular
- Specialized
- Dense irregular
- Dense regular
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Identify the region first. The arrow sits in the lower, thicker zone of the dermis, which is the reticular dermis lying beneath the thin papillary layer.
Step 2: Classify connective tissue by fibre density and orientation. When collagen bundles are abundant (dense) yet point in many directions (irregular), the tissue is dense irregular connective tissue, and this is exactly the texture of the reticular dermis.
Step 3: Functionally this design lets skin withstand pulling forces coming from all angles, which a tendon's parallel fibres could not do for the skin.
Step 4: Knock out the alternatives. Parallel densely packed fibres define dense regular tissue of tendons and ligaments; sparse loosely packed fibres define areolar tissue of the papillary dermis; cartilage, bone, blood and fat are the specialized connective tissues. None matches the reticular dermis. \[\boxed{\text{Dense irregular connective tissue}}\]
