What can spongy bone also called?
The spongy bones are also called Cancellous bones or the Trabecular bones. This bone is highly vascularized and consists of red bone marrow. Usually, spongy bone is situated at the end of long bones, with the surrounding of harder compact bone.
What is spongy bone also known as?
Cancellous bones are also known as the spongy bone or the trabecular bone. They are very light, porous bones enclosing numerous large spaces that help in giving them a sponge or a honeycomb appearance. Trabeculae is the primary anatomical and functional unit of the cancellous bone or the spongy bone.
What are some characteristics of spongy bone?
Spongy bone histology
- Connective tissue with blood vessels surrounds the periosteum of spongy bone
- Periosteum of the spongy bone sample
- Bony trabeculae in spongy bone structure
- Lacunae and osteoblast in the lacunae (at bony trabeculae)
- Marrow cavities in spongy substance of bone
- Blood vessels and hemopoietic tissue in marrow cavities
What does spongy porous bone is called?
Spongy bone, also called cancellous or trabecular bone, provides structural support and facilitates movement of the joints and limbs. Spongy bone is light and porous and found in most parts of the body and in other bones that do not typically endure large volumes of mechanical stress.
What are the other names for compact and spongy bone?
Alternative Names Compact Bone: Compact bones are also called cortical bones. Spongy Bone: Spongy bones are also called cancellous or trabecular bones.
What is another word for 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.
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.
What is the spongy bone mean?
Definition. (1) The osseous tissue that fills the interior or cavity of bones with a latticework of small spicules or flat pieces of mineralized bars (trabeculae) and interstices containing bone marrow or fat.
Where is the spongy bone?
Spongy bone is on the interior of a bone and consists of slender fibers and lamellae—layers of bony tissue—that join to form a reticular structure. Spongy bone is supplied by fewer and larger vessels than compact bone.
What is a flat bone?
Flat bones are made up of a layer of spongy bone between two thin layers of compact bone. They have a flat shape, not rounded. Examples include the skull and rib bones. Flat bones have marrow, but they do not have a bone marrow cavity. The skull is the bony structure of the head and face.
What is the cancellous?
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).
What is cortical and cancellous bone?
A Cortical and Cancellous Bone Cortical bone is a dense tissue that contains less than 10% soft tissue. Cancellous or spongy bone is made up of trabecules shaped as plates or rods interspersed between bone marrow that represents more than 75% of the cancellous bone volume.
What is spongy bone and compact bone?
Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Blood vessels and nerves enter the bone through the nutrient foramina to nourish and innervate bones.
What is spongy 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.
What forms spongy bone?
Spongy bone is composed of cells called osteocytes that sit in small cavities known as lacunae. The lacunae and their accompanying osteocytes are housed in the trabeculae matrix of the bone along with the bone marrow.
Where is cancellous tissue?
Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones. Compact tissue is also known as hard bone, compact bone or compact cortical bone.

What is bone in anatomy?
bone. [ bōn] 1. the hard, rigid form of connective tissue constituting most of the skeleton of vertebrates, composed chiefly of calcium salts. 2. any distinct piece of the skeleton of the body. See anatomic Table of Bones in the Appendices for regional and alphabetical listings of bones, and see color plates 1 and 2.
Which type of bone forms the surface layer of all bones and the shafts of long bones?
The hard, dense bone made of haver sian systems that forms the surface layer of all bones and the shafts of long bones, in contrast to spongy bone that forms the bulk of the short, flat, and irregular bones and the ends of long bones.
What happens when cartilage breaks loose?
Some of the cartilage cells break loose, so that channels develop in the bone shaft. Blood vessels enter the channels, bearing with them small cells of connective tissue, some of which become osteoblasts, cells that form true bone. The osteoblasts enter the hardened cartilage, forming layers of hard, firm bone.
What cells are responsible for forming new bone?
The osteoblasts enter the hardened cartilage, forming layers of hard, firm bone. Other cells, called osteoclasts, work to tear down old or excess bone structure, allowing the osteoblasts to rebuild with new bone. This renewal continues throughout life, although it slows down with age.
Which bone forms the roof of the nasal fossa?
ethmoid bone the sievelike bone that forms a roof for the nasal fossae and part of the floor of the anterior cranial fossa. See anatomic Table of Bones in the Appendices. facial b's the bones that form the skeleton of the face, including the hyoid, palatine, and zygomatic bones, the mandible, and the maxilla.
What is the outermost layer of bone?
Bone is not uniform in structure but is composed of several layers of different materials. The outermost layer, the periosteum, is a thin, tough membrane of fibrous tissue. It gives support to the tendons that secure the muscle to the bone and also serves as a protective sheath.
Why is bone replaced with fibrous tissue?
In osteitis fibrosa cystica, bone is replaced by fibrous tissue because of abnormal calcium metabolism. The condition usually is due to overactivity of the parathyroid glands. osteoma refers to abnormal new growth, either benign or malignant, of the tissue of the bones.
