With aging, bone density decreases in all groups. This inevitable bone loss is frequently the cause of osteoporosis. Data are from a study by Looker, Osteoporosis International This image shows trabecular bone structure in the lower spine of a young adult compared to an osteoporotic elderly adult. This is the area of bone to which ligaments and tendons attach. It is thick and dense. Trabecular bone, also known as cancellous bone or spongy bone, mainly serves a metabolic function. This type of bone is located between layers of compact bone and is thin and porous. Located within the trabeculae is the bone marrow. Macroscopic Bone Structure.
The skeletal system is the body system composed of bones, cartilages, ligaments and other tissues that perform essential functions for the human body. Bone tissue, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the internal support structure of the body. In the areas of the skeleton where whole. However, a significant difference between cortical bone 1st level structure and trabecular bone 1st level structure is the substantial variation in 1st level trabecular bone structure compared to cortical bone structure. Whereas most human adult structure is osteonal we a tight porosity range of 5 to 10%, human adult trabecular bone has a much.
Bone Basics and Bone AnatomyHave you ever seen fossil remains of dinosaur and ancient human bones in textbooks, television, or in person at a museum? It's easy to look at these and think of bones as dry, dead sticks in your body, but this couldn't be further from the truth. Bones are made of active, living cells that are busy growing, repairing themselves, and communicating. Be able to recognize compact and cancellous bone in conventional and ground sections and know the structural differences between the two types. Be able to identify the component parts of adult bone and know their functions (e.g. periosteum, endosteum, osteon, canaliculus, lacunae, osteocyte, Haversian systems/canals and Volkmann’s canals).
