Skin (integument) - General structure of the skin

3 important questions on Skin (integument) - General structure of the skin

Sense organs for touch, pressure, pain and temperature are found in the:
epidermis / subcutaneous fat layers / dermis?

Dermis

What is the most superficial layer of the epidermis?

The most superficial layer of the epidermis is the waterproof stratum corneum. (It is not comprised of living cells, hence affords the body great protection against dehydration and from bacteria in the same way that the peel of (say) an apple protects its contents.)

What is the deepest layer of the epidermis?

The deepest layer of the epidermis is the stratum basale (also called stratum germinativum)
  • keratinocytes are actively dividing.
  • Melanocytes also inhabit this layer and produce melanin.
  • Dendrocytes migrate to the skin from the bone marrow and become macrophages there.
  • Merkel cells are one of the many sensory receptors found in the skin.
