- Dermis
- Hypodermis
The <u>epidermis</u> can also be divided into <em>5 other layers</em> (<u>form outside to inside</u>):
- Stratum corneum: composed of corneocytes without nucleus
- Stratum lucidum: this stratum is <em>only in palms and soles</em>, and gives them the thick skin appearance
- Stratum granulosum: composed of keratinocytes whose nucleus disappear and left a granulated cytoplasm
- Stratum spinosum: keratinocytes connected via desmosomes
- Stratum basale: keratinocytes connected via hemidesmosomes. Melanocytes and Merckel cells can also be found in this layer.
