- Stratum Basale: The deepest bed where new keratinocytes are born.
- Stratum Spinosum: Provides strength and tractability to the cutis.
- Stratum Granulosum: Where cells begin to produce ceratin and lipids.
- Stratum Lucidum: Base only in thick skin like palm and sol.
- Stratum Corneum: The outmost bed of beat cell that sheds continuously.
The Dermis: The Structural Foundation
Positioned directly beneath the cuticle, the dermis is a thick, fibrous connective tissue level. It curb most the functional component of the cutis, include whisker follicles, oily secretor, and nervus endings.
