Is the dermis rich in blood vessels and nerve fibers?
Aug 28, 2017
Answer is definitely YES.
- Skin has superficial epidermis which is stratified epithelium sitting on basement membrane (BM). Below the non-cellular BM there lies dermis.
- Dermis is rich in blood capillaries and nerve endings (epidermis lacks both, nutrition is supplied to epidermal cells through diffusion).
- Blood brings in both oxygen and nutrients to skin. Blood circulation in skin also has role in maintaining temperature of body.
- Nerve endings help to feel pressure, heat, etc. Please read this to know morw: https://socratic.org/questions/how-do-the-nervous-and-the-integumentary-systems-work-together
