What is the difference of Reticular layer and the papillary layer of the dermis?

Answer 1

Both layers comprise the dermis; the papillary layer is the upper layer and the reticular layer is the lower. The papillary layer is loose areolar connective tissue and the reticular layer is a dense irregular connective tissue.

Answer 2

• The dermis and epidermis together form the basic body covering; the skin. They together perform the function of protecting internal organs from damage, dehydration, and disease.

• The cornified epidermis prevents damage by friction, and the dermis and the subcutaneous tissues prevent mechanical damage.

• Melanin, the dark pigment in chromatophores of the dermis, protects the body from UV radiation. The sebum and structure of the skin itself prevents the entry of pathogens.

Answer 3

The reticular layer is the deeper layer of the dermis composed of dense irregular connective tissue, providing strength and elasticity. The papillary layer is the superficial layer of the dermis containing loose connective tissue with capillaries, nerves, and touch receptors. The reticular layer is thicker and provides structural support, while the papillary layer is closer to the epidermis and is involved in nutrient exchange and sensation.
