Bone tissue, SEM

Bone tissue. Coloured scanning electron micrograph (SEM) of cancellous (spongy) bone. Bone tissue can be either cortical (compact) or cancellous. Cortical bone usually makes up the exterior of the bone, while cancellous bone is found in the interior. Cancellous bone is characterised by a honeycomb arrangement, comprising a network of trabeculae (rod-shaped tissue). These structuresprovide support and strength to the bone. The spaces within this tissue contain bone marrow (not seen), a blood forming substance.. Stunning Photo Gifts From Science Photo Library
