tiểu bì
Definition
- Noun (Anatomy, Biology):
- Cuticle: The thin, protective outer layer of an organism or part of an organism. In human anatomy, it often refers to the layer of skin, especially at the base of a fingernail or toenail. In botany, it refers to the waxy, protective film covering the epidermis of a plant leaf or stem.
- Epidermis (in specific contexts): While primarily "biểu bì" means epidermis, "tiểu bì" can sometimes be used in a more limited sense for thin, superficial skin layers or membranes.
