Rheum (/ËruËm/; from Greek: á¿¥Îµá¿¦Î¼Î± rheume a flowing, rheum), also known as gound, is thin mucus naturally discharged from the eyes, nose, or mouth during sleep (cf. mucopurulent discharge). Rheum dries and gathers as a crust in the corners of the eyes or the mouth, on the eyelids, or under the nose. It is formed by a combination of mucus (in the case of the eyes, consisting of mucin discharged from the cornea or the conjunctiva), nasal mucus, blood cells, skin cells, or dust. Rheum from the eyes is particularly common. Dried rheum is commonly called sleep, sleepy sand, eye goop or sleep dust. When the individual is awake, blinking of the eyelid causes rheum to be washed away with tears via the nasolacrimal duct.
Periosteum is a membrane that lines the outer surface of all bones, except at the joints of long bones. Endosteum lines the inner surface of all bones. Periosteum connsists of â¦ dense irregular connective tissue. Periosteum is divided into an outer fibrous layer and inner cambium layer (or osteogenic layer).The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts. The periosteum a membrane with a fibrous outer layer and a cellular inner layer. The periosteum isolates the bound surrounding the tissue, provides a route for the circu â¦ latory and nervous supply and actively particiapates in bone growth and repair.
