The cell membrane of a frog's skin epidermis can be described as having two distinct parts: an outer apical membrane and an inner serosal membrane.
Here's a breakdown:
- Apical Membrane: This membrane is formed by the outermost layer of cells in the epidermis.
- Serosal Membrane: This membrane is formed by the innermost layer of cells in the epidermis.
Tight junctions surround the apical margins of the outermost layer of cells. The frog skin epidermis behaves as a single compartment of P-cells with these two distinct membranes.
| Membrane Type | Location | Formation |
|---|---|---|
| Apical | Outermost layer of cells | Outermost layer of cells in the epidermis |
| Serosal | Innermost layer of cells | Innermost layer of cells in the epidermis |
