What are components of compact bone?
Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
What are the 4 main parts of compact bone?
Compact bone tissue is made of cylindrical osteons that are aligned such that they travel the length of the bone. Haversian canals contain blood vessels only. Haversian canals contain blood vessels and nerve fibers. Spongy tissue is found on the interior of the bone, and compact bone tissue is found on the exterior.
What are the components of Haversian system?
An Haversian system consists of an axial Haversian canal surrounded by concentric lamellae of bone. Lacunae lie between or within the lamellae, and in life these lacunae are occupied by osteocytes.
Which two minerals are the main components of bone?
The major minerals found in bone are calcium and phosphorus in the form of an insoluble salt called hydroxyapatite [chemical formula: (Ca)10(PO4)6(OH)2].
Which of the following is the major component of the bone labeled E?
Which of the following is the major component of the part of the bone labeled E? Yellow bone marrow within the medullary cavity is composed primarily of adipose tissue (fat).
What cells are found in compact bone?
compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.
What is the functional unit of compact bone?
The functional unit of compact bone is the osteon. The osteon is formed by concentric layers of compact bone called lamellae. These surround a central canal called the haversian canal. Trabeculae are the functional units of cancellous (spongy) bone.
