Inside of a bone showing the trabecular structure A typical carcinoid tumor of the lung showing a trabecular pattern of elongated groups of cells.. A trabecula (pl.: trabeculae, from Latin for 'small beam') is a small, often microscopic, tissue element in the form of a small beam, strut or rod that supports or anchors a framework of parts within a body or organ.
The trabecular bone score is a measure of bone texture correlated with bone microarchitecture and a marker for the risk of osteoporosis.Introduced in 2008, [1] its main projected use is alongside measures of bone density in better predicting fracture risk in people with metabolic bone problems.
Cancellous bone or spongy bone, [12] [11] also known as trabecular bone, is the internal tissue of the skeletal bone and is an open cell porous network that follows the material properties of biofoams. [13] [14] Cancellous bone has a higher surface-area-to-volume ratio than cortical bone and it is less dense. This makes it weaker and more flexible.
Thus the metaphysis contains a highly metabolic set of tissues including trabecular (spongy) bone, blood vessels, as well as marrow adipose tissue (MAT). The metaphysis may be divided anatomically into three components based on tissue content: a cartilaginous component ( epiphyseal plate ), a bony component (metaphysis) and a fibrous component ...
The trabecular bone is first resorbed by osteoclasts, creating a shallow resorption pit known as a "Howship's lacuna". Then osteoblasts deposit compact bone within the resorption pit. Eventually, the fracture callus is remodelled into a new shape which closely duplicates the bone's original shape and strength.
Trabecular bone (or cancellous bone) is the sponge-like bone in the ends of long bones and vertebrae. Cortical bone is the hard outer shell of bones and the middle of long bones. Because osteoblasts and osteoclasts inhabit the surface of bones, trabecular bone is more active and is more subject to bone turnover and remodeling.
The trabecular bone consists of cancellous bone that is located between the alveolar bone proper and the cortical plates. [15] The alveolar structure is a dynamic tissue which provides the jawbone with some degree of flexibility and resilience for the embedded teeth as they encounter numerous multi-directional forces. [16] [17]
Diploë (/ ˈ d ɪ p l oʊ i / or DIP-lo-ee) is the spongy cancellous bone separating the inner and outer layers of the cortical bone of the skull. [1] It is a subclass of trabecular bone.
