periosteum

 [per″e-os´te-um]
a specialized connective tissue covering all bones of the body, and possessing bone-forming potentialities. Periosteum also serves as a point of attachment for certain muscles. The connective tissues of the muscle fuse with the fibrous layers of periosteum. adj., adj perios´teal.

per·i·os·te·um

, pl.

per·i·os·te·a

(per'ē-os'tē-ŭm, -ă), [TA]
The thick, fibrous membrane covering the entire surface of a bone except its articular cartilage and the areas where it attaches to tendons and ligaments. In young bones, it consists of two layers: an inner cellular layer that is osteogenic, forming new bone tissue, and an outer fibrous connective tissue layer conveying the blood vessels and nerves supplying the bone; in older bones, the osteogenic layer is reduced.

Synonym(s): periost
[Mod. L. fr. G. periosteon, ntr. of adj. periosteos, around the bones, fr. peri, around, + osteon, bone]

(pĕr′ē-ŏs′tē-əm)

periosteum

The tissue that surrounds bone. Periosteum has an inner bone-forming (osteoblastic) layer, a middle fibrous layer and an outer layer containing many blood vessels and nerves.

periosteum

the CONNECTIVE TISSUE which surrounds the bone of vertebrates and to which are connected the MUSCLES and TENDONS. OSTEOBLASTS are present in the periosteum, and are important in bone repair after breakage.

Periosteum

However, when purulent secretion extends to the highly pneumatized root of the zygomatic process, the pneumatized bone can be eroded and purulent secretion can accumulate within the temporalis fossa once there is penetration through the periosteum. Purulent secretion can even track from the zygomatic root into the cheek to form mumps of the cheek, which usually misleads doctors to make an incorrect diagnosis.
