What's the difference between bone and periosteum?
Bone
Definition:
(n.) The hard, calcified tissue of the skeleton of vertebrate animals, consisting very largely of calcic carbonate, calcic phosphate, and gelatine; as, blood and bone.
(n.) One of the pieces or parts of an animal skeleton; as, a rib or a thigh bone; a bone of the arm or leg; also, any fragment of bony substance. (pl.) The frame or skeleton of the body.
(n.) Anything made of bone, as a bobbin for weaving bone lace.
(n.) Two or four pieces of bone held between the fingers and struck together to make a kind of music.
(n.) Dice.
(n.) Whalebone; hence, a piece of whalebone or of steel for a corset.
(n.) Fig.: The framework of anything.
(v. t.) To withdraw bones from the flesh of, as in cookery.
(v. t.) To put whalebone into; as, to bone stays.
(v. t.) To fertilize with bone.
(v. t.) To steal; to take possession of.
(v. t.) To sight along an object or set of objects, to see if it or they be level or in line, as in carpentry, masonry, and surveying.

(19) At consolidation, the distraction area was composed of lamellar trabecular and partly woven bone.
(20) Periodontal disease activity is defined clinically by progressive loss of probing attachment and radiographically by progressive loss of alveolar bone.
Periosteum
Definition:
(n.) The membrane of fibrous connective tissue which closely invests all bones except at the articular surfaces.
Example Sentences:
(1) The control periosteum contained a rich network of substance P immunofluorescent nerves.
(2) This flap is formed by a triangle-shaped excision combined with cranial and caudal slitting of the periosteum.
(3) In the periosteum of the human tibia, the arterial blood supply shows a general sectorial angioarchitecture.
(4) It is the manner in which the soft tissues and, in particular, the periosteum are handled that ultimately affects the results of the surgical treatment.
(5) In the area where the collagen was disorganized, and also near the periosteum, woven bone was first formed, which was then remodeled into lamellar bone.
(6) Orthopedic new approaches to therapy of OA include removal of abnormal tissue to stimulate repair (e.g., burring, abrasion) and grafting (e.g., osteochondral grafts, perichondrium, periosteum) to the subchondral bone.
(7) Treated embryos showed a delay in the longitudinal growth of the tibia, as well as in the growth of all structures enclosed by the perichondrium-periosteum.
(8) It also shows that the periosteum has the leading role in the restructuring process of these grafts.
