Test. The remainder of the osseous structures are intact. Created by. Bone is composed of an extracellular matrix and bone cells (osteocytes).Under the right conditions, bone tissue undergoes a process of mineralization, formed by collagen matrix and hardened by deposited calcium. Bone Surface Markings.MARKING DESCRIPTION EXAMPLE Depressions and Openings: sites allowing passage of soft tissue (nerves, blood vessels, ligaments, tendons) or formation of joints Fissure Narrow slit or groove between adjacent parts of bone through which blood vessels, nerves or ligaments pass. On MRIs, the calcification appears as areas of decreased signal intensity on T1-weighted images, whereas T2-weighted images may show increased signal . The skeletal system stores minerals and fats and produces blood cells. These three bones converge to form the acetabulum, a deep socket on the outer edge of the pelvis. Tendons are muscle-to-bone linkages to stabilize the bony skeleton (or to produce motion), while ligaments are bone-to-bone linkages to restrict relative motion. Canaliculi-narrow passageways 2. The use of 3D imaging is particularly valuable for delineating the nature of bony involvement and its extent for preoperative planning [ 16, 63 ]. In certain conditions, nonosseous structures other than the urinary tract are seen on the bone scan. Cancellous bone . Protection - many soft tissues and organs are surrounded by skeletal structures. adenoid tissue lymphoid tissue . In this Chapter the authors describe, in detail, the normal anatomy and function of the osseous and soft tissue stuctures of the back and pelvis.
