The skeletal system consists of four types of connective tissue: ?, ?, ?, and ?
Cartilage, bone, bone marrow, periosteum
Bone or ? Tissue contains matrix consisting of inorganic minerals, ?, and an organic component (mostly ? Fibers)
Osseous, salts, collagen
Four types of cells in bone tissue: ?
Osteoprogenitor, osteoblasts, osteocytes, osteoclasts
? Cells undergo mitosis to become osteoblasts
? And ? Have no mitotic potential
? Maintain daily cellular activities of bone tissue
? Develop from a type of white blood cell called monocyte. They function in bone ? That is important in the growth, development, maintenance, and repair of bone
The matrix of bone contains abundant mineral salts, primarily ?? And ??
Calcium phosphate, calcium carbonate
The deposition of calcium slats by osteoblasts in the framework formed by the collagen fibers of the matrix
Bone is not completely ?
The spaces in bone provide channels for blood vessels that supply bone cells with ?, make bones ?, and determine whether bone is ? Or ?
Nutrients, lighter, compact, spongy
? Bone forms the external portions of all bones and the bulk of the shaft of long bones
? Bone tissue provides protection and support and helps long bones resist the stress of weight placed on them
Nutrient arteries and nerves from the ? Penetrate compact bone through perforating (?) canals
The blood vessels from the perforating canals connect with the blood vessels and nerves of the ? Cavity and those of the ? (Haversian) canals
Rings of hard, calcified matrix
Between the lamellae are small spaces called ? Which contain osteocytes
Projecting from the lacunae are minute canals called ?
Collectively, the central canal, lamellae, lacunae, osteocytes, and canliculi, is called an ? Or ? System
Adult ? bone is the only connective tissue that has a basic structural unit- the ?- associated with it
? Or cancellous bone does not contain ?
? Bone consists of an irregular latticework of thin plates of bone called ?
The spaces between trabeculae of some bones are filled with ? Bone marrow
Within the trabeculae lie ?, which contain
Blood vessels from the ? Provide nutrients to osteocytes
? bone makes up most of the bone tissue of short, flat, irregular bones and most of the ? Of long bones
The process by which bone forms
Ossification begins about the ? Or ? Well of embryonic life and continues throughout adulthood
There are two types or ossification: ? And ?
Most of the surface of skull bones and the clavicles are formed in this way
At the site where bone will develop, cells in ? Differentiate into osteoprogenitor cells then into osteoblasts
The space between the trabeculae is filled with ? Bone marrow
