- Myoepithelium
The myoepithelial cells are flattened cells with long cytoplasmic processes lie between the secretory cells and the basement membrane.
The processes form a basket-like network (hence the name basket cells) around the secretory units. Their cytoplasm is rich in contractile actin and myosin filaments.
Contraction of these cells forces the secretory product into the duct system. The myoepithelial cells are found in sweat and mammary glands.
- Neuroepithelium
It is a special type of epithelium designed to receive sensory stimuli (e.g., taste buds and olfactory epithelium). It will be considered with the digestive and the respiratory systems.
