The answer is conjunctiva.
The epithelium covering the inner surface of the eyelids is called the palpebral conjunctiva, while the outer surface of the eye is covered by the bulbar conjunctiva.
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.
Fish scales are not made of epithelium. Fish scales are made of a hard material called dermal bone, which is produced by specialized cells in the skin called osteoblasts. Epithelium is a type of tissue that covers the surface of the skin and organs.
Ciliated epithelium is a type of tissue in the human body that contains hair-like structures called cilia. These cilia help move substances along the surface of the tissue, such as mucus in the respiratory tract. Ciliated epithelium is found in areas like the respiratory tract, fallopian tubes, and parts of the brain.
The type of epithelium that secretes its products into ducts opening onto surfaces is called glandular epithelium. This includes exocrine glands, which release their secretions through ducts to external surfaces or internal cavities, such as sweat glands, salivary glands, and the pancreas. These glands are characterized by their ability to produce substances like enzymes, sweat, or mucus that serve various functions in the body.
Surface that touch food are called "food contact surfaces".
The total area of all surfaces of an object is called the surface area. It is a measure of how much exposed surface the object has.
Surface tension.
Regeneration
Ciliated epithelium consists of columnar or cuboidal cells with hair-like structures called cilia on their surface. The cilia beat in a coordinated motion to move substances along surfaces within the body, such as mucus or particles in the respiratory tract or reproductive system. This helps to clear debris, pathogens, and maintain proper physiological functions.
The sum of all the areas of a surface of a solid is called the 'surface area'.
Relaxation of the eyelids is called blepharochalasis.
