4 Οκτ 2019 · Spongy bone, also known as cancellous bone or trabecular bone, is a very porous type of bone found in animals. It is highly vascularized and contains red bone marrow. Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it.
21 Νοε 2023 · Spongy bone, also known as cancellous bone, is composed of a lattice-like arrangement of osteocytes known as trabeculae. Trabeculae form a mesh-like network of bony spicules of varying size that are aligned along regions of biomechanical stress.
27 Ιουλ 2024 · One of the primary functions of spongy bone is hematopoiesis, the production of blood cells. The red bone marrow found within the trabecular spaces is the site where red blood cells, white blood cells, and platelets are generated. This process is crucial for maintaining healthy blood cell levels and supporting the body’s immune system.
Spongy bone provides balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily. In addition, the spaces in some spongy bones contain red bone marrow, protected by the trabeculae, where hematopoiesis occurs.
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution.
25 Σεπ 2024 · Both the epiphyses and metaphyses have a thin cortical layer of compact bone that is filled with a porous bone arrangement called spongy bone. The spaces within the spongy bone are filled with red bone marrow containing the stem cells for blood cell production (the process of hematopoesis).
17 Οκτ 2022 · Cartilage has many functions, including the ability to resist compressive forces, enhance bone resilience, and provide support in bony areas where flexibility is needed (see Image. Cartilage and Bone Illustration). The primary cell that makes cartilage is the chondrocyte, which resides within the lacunae.
