Mucous membranes

Membranes that line body cavities open to the exterior, secreting mucus.

Serous membranes

Membranes that line body cavities not open to the exterior, consisting of visceral and parietal layers.

Derivatives of the skin

Includes sweat glands, oil glands, hair, and nails.

Sebaceous glands
