Which layer of the dermis is made of collagen and elastin?

  1. Stratum Basal

  2. Stratum Spinosum

  3. Reticular layer

  4. Subcutaneous layer

The correct answer is: Reticular layer

The correct answer is the reticular layer. The reticular layer of the dermis is the deepest layer and is primarily made up of collagen and elastin fibers, which provide structural support and elasticity to the skin. The other options, such as the Stratum Basal, Stratum Spinosum, and Subcutaneous layer, do not contain collagen and elastin in the same concentration or function as the reticular layer.
