The ex vivo micro-CT images of each femur … 5. The key difference between trabecular and cortical bone is that the trabecular bone is the more porous inner regional layers of the body that produces red blood cells while the cortical bone is the rigid outer regional layers of the bone that stores fat. The endosteum is a vascular connective tissue. Trabecular bone displays significantly higher absolute asymmetry than cortical bone. Therefore, it appears that the discrepancy in muscle’s relationship with trabecular vs. cortical bone is driven, in large part, by the dependence of the cortical bone architecture measures on femur length. Hence, bone plays a metabolic role in the body. Spongy bone and cancellous bone are synonyms of trabecular bone. The key difference between trabecular and cortical bone is that the trabecular bone is the more porous inner regional layers of the body that produces red blood cells while the cortical bone is the rigid outer regional layers of the bone that stores fat. Analysis of individual bands showed cortical bone to have compositional characteristics of older bone when compared with trabecular material, possibly due to the higher bone turnover traditionally reported in the trabecular compartment. Location Compact bone makes up the outer covering of bone while the trabecular bone makes up the inner cavity of a bone. There were significant correlations between: cortical AI and (1) serum AI (r = 0.71, p less than 0.001); (2) duration of dialysis with softened water (AI content, 55 +/- 21 micrograms/L, r = 0.65, P less … Compact bone is composed of many cylinder shaped units called osteons, or Haversian Systems (after the anatomist who discovered them.) Trabecular bone fills the inner region of the long bones while cortical bone makes the outer layer of the long bones. The cortical bone encrircling each slice was trimmed off with a cleaver, leaving intact a lacy slice of trabecular bone. Bone strength is determined by collagenous proteins (tensile strength) and mineralized osteoid (compressive strength). The trabecular bone sample with two sides sealed by two cortical plates with thicknesses of 1.00 and 2.00 mm exhibited a higher mean SOS compared to the samples with one cortical endplate. The excised femurs and mandibles were thawed to room temperature for 3 hours before micro-CT scanning. The key difference between trabecular and cortical bone is that the trabecular bone is the more porous inner regional layers of the bone while cortical bone is the rigid outer regional layer of the bone. Summary. Cortical and Trabecular Bone: The bones of our skeleton are made up of two types of bone tissue - cortical bone, which is about 80% of bone mass, and trabecular bone, which is about 20% of bone mass. Therefore, it facilitates the space for blood vessels and red bone marrow. Moreover, trabecular and cortical compartments of bone play a major role in accomplishing these functions. In osteoporosis, cancellous bone is more severely affected than cortical bone. For trabecular bone properties, a 1 mm thick VOI was analyzed beginning 0.5 mm distal to the proximal tibial growth plate. Cortical bone is about 90% calcified by volume whereas trabecular bone is about 25% calcified. All femurs and mandibles were scanned parallel to the transverse plane and coronal plane, respectively, by using micro-CT. Compact bone is also known as the cortical bone while the trabecular bone is also known as spongy bone or cancellous bone. The marrow substance was washed away by fine and powerful jets of tap water obtained from an adjustable nozzle. 6. Cancellous bone, also called trabecular or spongy bone, is the internal tissue of the skeletal bone and is an open cell porous network.

Cortical bone is dense and forms the surface of bones. There was also a significantly greater total bone mass in the dominant extremity which we attributed to greater cortical mass (P <0.025) given the highly significant correlation (r 2 =0.904, P =0.0001) between total and cortical bone mass and the less significant correlation between total and trabecular bone mass (r 2 =0.479, P =0.0001). 1.”Bone cross-section”By Pbroks13 – Own work, (CC BY 3.0) via Commons Wikimedia   Trabecular bone is the osseous tissue present in the mid-region of the bones. Abstract– Spinal cord injury (SCI) triggers rapid loss of trabecular bone mineral density (BMD) in bone epiphyses and a loss of cortical cross-sectional area (CSA) in bone diaphyses, increasing fracture risk for people with SCI. It is also referred to as compact bone. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V.
