What type of bone forms a latticework within an individual bone?
Bone tissue that consists of an irregular latticework of thin plates of bone called trabeculae; found inside short, flat, and irregular bones and in the epiphyses of long bone.
What is bone with a latticework structure called?
cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.
What bones form inside?
The inside of your bones are filled with a soft tissue called marrow. There are two types of bone marrow: red and yellow. Red bone marrow is where all new red blood cells, white blood cells, and platelets are made. Red bone marrow is found in the center of flat bones such as your shoulder blades and ribs.
Which type of bone is found inside most bones?
The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels.
Is there spongy bone in the diaphysis?
The central tubular region of the bone, called the diaphysis, flares outward near the end to form the metaphysis, which contains a largely cancellous, or spongy, interior. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate.
What is the formation of bone tissue?
The process of bone formation is called osteogenesis or ossification. In this process, mesenchymal cells proliferate into areas that have high vascularization in embryonic connective tissue in the formation of cell condensation or primary ossification centers.
Are bones organs or tissues?
Bones are organs that consist primarily of bone tissue, also called osseous tissue. Bone tissue is a type of connective tissue consisting mainly of a collagen matrix that is mineralized with calcium and phosphorus crystals.
How are osteocytes arranged in the spongy bone?
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)).
What are the gross characteristics of a long bone?
Anatomy of a Long Bone A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. Red marrow fills the spaces in the spongy bone.
Which is a tube shaped structure in the bone?
Osteon: tube shaped structure in bones with an open space for blood vessels, veins, and nerves in the center. Platelet: a small cell fragment without a nucleus that helps stop blood the flow of blood when the body is injured.
What is the function of the matrix in compact bone?
The densely packed concentric rings of matrix in compact bone are ideal for resisting compressive forces, which is the function of compact bone. The open spaces of the trabeculated network of spongy bone allow spongy bone to support shifts in weight distribution, which is the function of spongy bone.
