By which process are the bones of the roof of the cranium formed. Atlas has no vertebral body, is essentially a ring of bone with transverse processors that axis slots into like a peg. Wolff's Law states that bones will adapt to the degree of mechanical loading, such that an increase in loading will cause the architecture of the internal, spongy bone to strengthen, followed by the strengthening of the cortical layer. (b) In this micrograph of the osteon, you can see the concentric lamellae around the central canals. What are 4 sites where endochondral ossification occurs? Bone disease - Bone disease - Fractures: A fracture occurs when the bone tissue is subjected to tensile, compressive, or shear forces in excess of its strength. Bone in human and other mammal bodies is generally classified into two types 1: Cortical bone, also known as compact bone and 2) Trabecular bone, also known as cancellous or spongy bone. These two types are classified as on the basis of porosity and the unit microstructure.

It is found more at the ends of long bones as it is more flexible than cortical bone. The cancellous bone, in turn, forms the internal tissue of bones and is spongy and less dense. Macica CM, King HE, Wang M, McEachon CL, Skinner CW, Tommasini SM. Osteoclasts excavate a cylindrical tunnel, forming a cutting cone. Mesenchymal tissue is directly replaced by bone with no cartilage intermediate as mesenchymal cells differentiate into osteoblasts, which produce bone directly. Collagenous mesenchymal tissue is replaced by woven bone, Immature or primitive bone seen in fetus and the newborn, or preceded by a fracture. It is solid in appearance, and constitutes 80% of total bone mass. In long bones, as you move from the outer cortical compact bone to the inner medullary cavity, the bone transitions to spongy bone. Which 4 form the cranial cavity? We hypothesized that reduction in overall bone density leads to local reductions in bone density and cortical thickness in cadaveric sacra that match clinically observed fracture patterns in patients with sacral insufficiency fractures.
