Cancellous bone, also known as trabecular or spongy bone, contains red bone marrow, which is involved in the production of blood cells. This type of bone features a network of trabeculae that create a porous structure, allowing for the storage of marrow. In contrast, compact bone is denser and primarily serves as a structural support, lacking the same extensive marrow spaces found in cancellous bone.
What else can I help you with?
Is the compact bone another name for cancellous bone?
No cancellous bone is also known as spongy bone
Which type of bone tissue significantly degenerates first in osteoporosis?
Spongy (or cancellous) bone is significantly degenerated by osteoporosis.
What is cancellous tissue?
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
Which one is found in a compact bone but not in a spongy bone?
Haversian systems (osteons) are found in compact bone but not in spongy bone. These structures consist of concentric layers of bone tissue surrounding a central Haversian canal containing blood vessels and nerves.
Another name for spongy bone is this?
Cancellous bone. It is the less dense and more porous type of bone tissue found in the interior of bones.
What are two names of bone tissues?
Compact Bone, makes up the dense material in a long section of a bone. Cancellous bone, is found in the end regions of long bones and hs plates of bone interspersed with bone marrow.
Is compact bone located in the diaphysis or the epiphyses?
Compact bone is dense and solid in appearance and cancellous bone is characterized by open space partially filled with needle-like structures. Compact bone is found in the main shaft of long bones called the diaphysis. Its' function is to provide strong support without cumbersome weight.
Is the diaphysis of a long bone composed of a spongy bone?
No, the diaphysis of a long bone is primarily composed of compact bone, not spongy bone. The compact bone surrounding the central medullary cavity provides strength and support to the bone, while spongy bone is typically found at the ends of long bones.
What are the main bone textures?
The main bone textures are cortical (or compact) bone, which is dense and forms the outer layer providing strength and support, and trabecular (or cancellous) bone, which is spongy and found within the interior of bones, aiding in shock absorption and reducing weight. Additionally, bone can exhibit varying degrees of porosity and surface features, such as osteons in compact bone and trabeculae in cancellous bone, which contribute to its overall structure and function. These textures allow bones to fulfill their roles in the skeletal system effectively.
What is in the middle of a long bone?
A long bone consists of: Periosteum, articular cartilage, medullary cavity, endosteum, cancellous bone, blood vessels, and compact bone.
What is the layer of spongy bone found between two layers of compact bone in short?
The layer of spongy bone found between two layers of compact bone is known as the trabecular or cancellous bone. This structure provides strength and support while remaining lightweight, facilitating the distribution of forces and stresses. It is typically found in flat bones, such as the skull, and helps in the production of blood cells within the bone marrow contained in its spaces.
What type of bone tissue to contain marrow?
Bone marrow is primarily found within cancellous (spongy) bone tissue. This type of bone has a porous structure that allows for the accommodation of bone marrow, which is responsible for producing blood cells. In contrast, compact bone, which is denser and forms the outer layer of bones, does not contain marrow. Both types of bone are essential for overall skeletal function, with cancellous bone playing a critical role in hematopoiesis.
