HEMATOPOIESIS- the normal formation and exploitation of blood cells in the fig out marrow. In severe genus Anemia and other hematologic disorders, cells may be produced in organs outside the marrow (extramedullary hematopoiesis). See also erythropoiesis.
DIAPHYSIS- 1. the shaft of a long chock up, between the epiphyses.
2. the portion of a long bone formed from a primary center of ossification.
EPIPHYSIS- 1. The end of a long bone that is originally separated from the main bone by a storey of cartilage but that later on becomes united to the main bone through with(predicate) ossification.
HYALINE CARTILAGE- a type of connectedness tissue composed of specialized cells in a translucent, pearly blue matrix. Hyaline cartilage light covers the articulating ends of bones, connects the ribs to the sternum, and supports the nose, the trachea, and part of the larynx. It is covered by a membranous perichondrium, drop where it coats the ends of bones, and tends to calcify in advanced age
PERIOSTEUM- a thick, fibrous vascular membrane covering the bones, except at their extremities. It consists of an outer layer of collagenous tissue containing a few fat cells and an sexual layer of fine elastic fibers.
Periosteum is permeated with the nerves and blood vessels that innervate and nourish underlying bone. The membrane is thick and markedly vascular over young bones but thinner and slight vascular in later life. Bones that lose periosteum through injury or disease usually scale or die.
COMPACT BONE- lamellar bone the normal type of adult bone, organise in layers (lamellae), which may be parallel ( cellular b.) or concentrically set (compact b.).
MARROW CAVITY-
ENDOSTEUM- n a thin layer of connective tissue that lines the walls of the bone marrow cavities and haversian canals of compact bone and covers the trabeculae of cancellous bone. It has both osteogenic and hematopoietic potencies and, like the periosteum, takes an active part in the...If you want to get a full essay, order it on our website: Ordercustompaper.com
