Beneath the periosteum lie the dense hard layers of bone tissue called compact bone. Osteons in compact bone tissue are aligned in the same direction along lines.
Instead the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae singular trabecula Figure 638.
A canaliculus of compact bone contains. A canaliculus of compact bone contains. An abundance of collagen fibers. A process of an osteocyte.
There is a different layer of connective tissue proper that lines all the internal cavities of bones the central canals of osteons in compact bone and the exterior surface of trabeculae in. Like compact bone spongy bone also known as cancellous bone contains osteocytes housed in lacunae but they are not arranged in concentric circles. Instead the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae singular trabecula Figure 638.
These spaces are called lacunae and they house bone-producing cells called osteocytes which are united through a network of canals called canaliculi. The canaliculi supply nutrients via blood. 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.
They are Harvesian canal Lamellae Lacunae and canaliculi. CANALICULUS- a small channel or canal connecting two lacunae in compact bone. Each caniliculus contains a cellular process of an osteocyte.
OSTEON- basic unit of structure in adult compact bone consists of a central canal ith lamellae of matrix lacunae osteocytes and caniliculi. Compact bone tissue consists of units called osteons or Haversian systems. The Haversian canal osteonic canal contains the bones blood vessels and nerve fibers Figure 1.
Osteons in compact bone tissue are aligned in the same direction along lines. Compact bone is a subtype of bone that is found on the periphery of bones. Compact bone contributes to the strength and hardness of bone especially on the outer surface of long bones.
Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes called filopodia project into these canals. These cytoplasmic processes are joined together by gap junctions.
The periosteum contains blood vessels nerves and lymphatic vessels that nourish compact bone. Tendons and ligaments also attach to bones at the periosteum. The periosteum covers the entire outer surface except where the epiphyses meet other bones to form joints Figure 68.
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. The periosteum forms the outer surface of bone and the endosteum lines the medullary cavity.
Flat bones like those of the cranium consist of a layer of diploë spongy bone lined on either side by a layer of compact bone The two layers of compact bone and the interior spongy bone work together to protect the internal organs. Beneath the periosteum lie the dense hard layers of bone tissue called compact bone. Its composition is fibrous rather than solid and it gives bone its resiliency.
Encased within these layers is the tissue that makes up most of the volume of bone called cancellous or spongy bone because it contains little hollows like those of a sponge. It contains red marrow forms blood cells In embryonic and fetal development bones are ormed in either hyaline cartilage or fibrous con- the subsequent deposition of calcium salts by called osteoblasts which form the bone matrix other connective tissues bone is continually mo and reconstructed.

Kănə-lĭkyə-ləs nplcanaliculi-lī A small canal or duct in the body such as the minute channels in compact bone. The American Heritage Medical Dictionary Copyright 2007 2004 by Houghton Mifflin Company. Contains small blood lie at right angles to the long axis of the bone and connect structural unit of compact bone.
Skeletal system histology of compact bone. Osteocyte canaliculus lacuna lamella central canal cement line interstitial lamella osteon. Singular canaliculus channels within the bone matrix that house one of an osteocytes many cytoplasmic extensions that it uses to communicate and receive nutrients cartilage semi-rigid connective tissue found on the skeleton in areas where flexibility and smooth surfaces support movement.
A lacuna never contains. Any of many small canals or ducts in the body such as in the bone or in some plants. In anatomy a canaliculus is a small canal or duct or passageway in the body.
What are the two types of bone. Bones are composed of two types of tissue. A hard outer layer called cortical compact bone which is strong.
Which one of the following is found in compact bone but not in spongy bone. Not all compact bone is organized around a central canal with concentric lamellae. Lamellae found in the inner and outer boundaries of dense bone run parallel to the bone surface.
The compact bone basic unit is the osteon or Haversian System. There are no osteons in spongy bone but it is composed of lamellae osteocytes lacunae and canaliculi. Dense no spaces or hollows in the bone matrix visible to the eye.
Forms the thick-walled tube of the shaft or diaphysis of long bones which surrounds the marrow cavity or medullary cavity. A thin layer of compact bone also covers the epiphyses of long bones.
