The skin's main structure consists of three distinct layers.
Skin Layers
Here is a breakdown of the skin's main layers as detailed in the reference:
Epidermis
- The outermost layer of the skin.
- It is an elastic layer that is constantly being renewed.
- Keratinocytes are the primary cells, which are created through cell division at the base of the epidermis.
Dermis
- (Not detailed in reference) But it lies beneath the epidermis.
- It contains important structures like blood vessels, nerve endings, and hair follicles.
Subcutaneous Layer
- (Not detailed in reference) Also known as the hypodermis.
- This is the innermost layer, primarily composed of fat and connective tissue.
These three layers work together to provide protection, regulate temperature, and allow us to interact with our environment.
| Layer | Description | Key Components |
|---|---|---|
| Epidermis | Outermost, elastic, constantly regenerating | Keratinocytes |
| Dermis | Middle layer, containing support structures | Blood vessels, nerve endings, hair follicles |
| Subcutaneous | Innermost layer, composed of fat and connective tissue | Fat and connective tissue |
