MICROANATOMY

Detailed explanation-1: -Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.

Detailed explanation-2: -Trabecular bone tissue is a hierarchical, spongy, and porous material composed of hard and soft tissue components which can be found at the epiphyses and metaphyses of long bones and in the vertebral bodies (Fig.

Detailed explanation-3: -Spongy bone tissue is composed of trabeculae and forms the inner part of all bones.

Detailed explanation-4: -Trabecular bone is a highly porous (typically 75–95%) form of bone tissue that is organized into a network of interconnected rods and plates called trabeculae which surround pores that are filled with bone marrow.

Detailed explanation-5: -Cortical bone The vertebrae are largely composed of trabecular bone as is the lower end of the radius and ulna (bones in the forearm fractured with colle’s fractures).
