Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).
Which bones are cortical bones?
Cortical bone refers to the thick outer surface of typically a long bone [for example humerus or femur shaft] that ensheathes the cavity of the bone called medulla.
What is the function of cortical bone?
Cortical bone is the dense outer surface of bone that forms a protective layer around the internal cavity. This type of bone also known as compact bone makes up nearly 80% of skeletal mass and is imperative to body structure and weight bearing because of its high resistance to bending and torsion.
What is the difference between cortical bone and cancellous bone quizlet?
It is as hard as cortical bone, but it is formed in such a way as to appear spongy or mesh-like. Cancellous bone comprises most of the bone in the axial skeleton, including the bones of the skull, ribs, ears, and spine.
What is the difference between compact bone and cancellous bone?
The key difference between compact and cancellous bone is their structure. Compact bone is the harder outer shell of the bone while cancellous bone is the inner porous, less dense layers of the bone. Bones are important components in assisting movement and granting a shape to the body.
Which bone is made up of cancellous bone tissue?
The mineralized matrix of bone tissue has an organic component of mainly collagen called ossein and an inorganic component of bone mineral made up of various salts. Bone tissue is a mineralized tissue of two types, cortical bone and cancellous bone. …

Is the femur cancellous bone?
Spongy Bone (Cancellous Bone) Spongy bone is supplied by fewer and larger vessels than compact bone. These vessels perforate the outer compact layer and are distributed into the spongy portion of bone, which is filled with marrow. Bone marrow is tissue found in long bones, like the femur, that contains stem cells.
Is alveolar bone cancellous?
The trabecular bone contains cancellous bone, which is located between the alveolar bone proper in addition to the plates of cortical bone. The alveolar bone is located between two neighboring teeth is the interdental septum.
Is mandible cancellous bone?
The cancellous bone thickness in the mandible was thinnest in the CI-ID and thickest in the C-mid, and on each level, the average thickness was thickest at L2 (4.74 mm) and thinnest at L4 (4.21 mm). … In addition, the cancellous bone thickness and bone quality are important for implant placement.
What is the function of the cancellous bone?
Cancellous bone makes up about 20 percent of the human skeleton, providing structural support and flexibility without the weight of compact bone. It is found in most areas of bone that are not subject to great mechanical stress.
Why is spongy bone called cancellous?
Cancellous bone is also known as spongy bone because it resembles a sponge or honeycomb, with many open spaces connected by flat planes of bone known as trabeculae. Inside the trabeculae are three types of bone cells: osteoblasts, osteocytes and osteoclasts. Osteoblasts are the cells that make new bone.
What is another name for cortical 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 difference between cortical bone tissue and trabecular bone tissue quizlet?
Cortical bone is sometimes called dense or compact bone. It comprises 80% of adult bone mass. … The latticelike matrix of trabecular bone has small cavities that can be filled with marrow or connective tissue. Trabecular bone is predominant in the ends of long bones, vertebrae, rib cage, and flat bones of the pelvis.
What is the major difference between compact and spongy bone quizlet?
Compact bone has more bone matrix and less space due to osteons. Spongy bones have less bone matrix and more space due to trabeculae. You just studied 4 terms!
What are the two types of bone tissue quizlet?
Compact and cancellous (spongy) bone are two types of bone tissue.
What is the difference between a flat bone and a spongy bone?
Flat bones are made up of a layer of spongy bone between two thin layers of compact bone. … Examples include the skull and rib bones. Flat bones have marrow, but they do not have a bone marrow cavity.
How do spongy and compact bone look different?
How do spongy and compact bone look different? Yellow marrow: Substance composed of fat found in the medullary cavity of long bones in adults. Spongy bone looks cancellous, whereas compact bone appears to be solid, smooth, and dense. … As the bone matrix is broken down, ionic calcium is released into the blood.
What are the 2 types of bone What is the difference between the two?
Compact and spongy bones are considered the two basic structural bone types. The best explanation of the difference between the two is that the spongy bones in terms of area can be found at the head part of long bones. … Compact bones are also known as cortical bones. Spongy bones are also known as cancellous bones.
Which bone tissue is also known as cancellous bone quizlet?
Spongy Bone Tissue. Also referred to as trabecular or cancellous bone tissue, does not contain osteons. Spongy bone tissue is always located in the interior of a bone, protected by a covering of compact bone. It consists of lamellae that are arranged in an irregular pattern of thin columns called trabeculae.
Which of the following are found in cancellous bone?
Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
Is cancellous bone Osteoinductive?
Cancellous bone grafts consist predominantly of trabecular bone tissue. Cancellous bone has higher osteogenic and osteoinductive properties than cortical bone and a larger number of progenitor cells and osteoblasts.
Is the tibia a cortical bone?
In the human tibia, we have shown that (1) the cortical structure is highly adapted to compression stresses throughout the bone, with a smoothly variable adaptation to bending and torsion which reaches maximum effectiveness at the mid diaphysis (2), and (2) in long-distance runners, the pQCT-assessed cortical mass and …
Which bones are spongy?
Spongy Bone Definition Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it. It is also found inside the vertebrae, in the ribs, in the skull and in the bones of the joints.
Is spongy bone soft?
Pores are filled with marrow, nerves, and blood vessels that carry cells and nutrients in and out of the bone. Though spongy bone may remind you of a kitchen sponge, this bone is quite solid and hard, and is not squishy at all. The inside of your bones are filled with a soft tissue called marrow.
What is fenestration and dehiscence?
Fenestration is the condition, in which the bony coverage of the root surface is lost, and the root surface is only covered by the periosteum and gingiva. In such lesions, marginal bone is intact. When this bone defect spreads toward the marginal bone, it is called dehiscence.[1]
Is mandible cortical bone?
Cortical bone thickness was highest in the posterior mandible (1.15 ± 0.42 mm), followed by the anterior mandible (1.01 ± 0.32 mm), anterior maxilla (0.89 ± 0.26 mm), and posterior maxilla (0.72 ± 0.19 mm). … Cancellous bone density and cortical bone thickness varies by implant site in the four regions of the jawbone.
Is maxilla a cortical bone?
Cortical bone in the maxilla, mesial and distal to canine interradicular sites, was thickest while thickness in the mandible exhibited a gradual anterior to posterior increase.
Is the mandible compact or cancellous bone?
The mandible is subject to vertical atrophy and the maxilla is primarily subject to horizontal atrophy. The mandible possesses more compact bone, the maxilla more spongy; the resorption directions also differ (mandible: towards the oral aspect; maxilla: towards the vestibular).
Which type of bone is maxilla?
The maxilla (plural: maxillae /mækˈsɪliː/) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. …
