What's the route taken by nutrients though a bone, starting with the periosteum and ending with an osteocyte in a lacuna? The path is: Periosteum, Perforating Canals, Central Canals, Canaliculi, Lancunae, Osteocytes
In embryogenesis, the skeletal system is derived from the mesoderm germ layer. Chondrification (also known as chondrogenesis) is the process by which cartilage is formed from condensed mesenchyme tissue, which differentiates into chondrocytes and begins secreting the molecules that form the extracellular matrix. (wikipedia)
Cartilage that has eroded to this point has to be repaired surgically. There is now evidence that blood vessel disorders like atherosclerosis found in Heart disease, Diabetes, obesity, and hypertension can impair the blood supply to this bone that lies beneath the cartilage. This can further starve cartilage of its nutrient and oxygen supply. In this way, healthy blood vessels might contribute to healthy joints.
Since cartilage does not have a vascular supply it receives all nutrients through diffusion.
diffusion through the matrix
Surrounding synovial fluid
Cartilage does not have any vascularization - it gets all its nutrients via diffusion from the surrounding extracellular matrix.
False
The cartilage that forms the Adam's apple is the thyroid cartilage.
It keeps the bones slightly apart, protecting their cartilage coverings from wear and tear It absorbs shocks, again protecting the cartilage It lubricates the joint, helping it to work freely and easily It acts as a filter, letting nutrients reach the cartilage, but blocking the passage of harmful cells and substances
Hyaline Cartilage and Articular Cartilage get their nutrients through synovial or perichondrium fluid. Fibrocartilage does not have these so it gets nutrients through blood capillaries.
Bone has more resilience, cartilage has faster regeneration, and cartilage is avascular.
Surrounding synovial fluid
False, cartilage gets most of its nutrients via diffusion of nutrients from synovial fluid. The cells in the fibrous synovial membrane that produce synovial fluid are richly vascularized.
It gets oxygen and nutrients through simple diffusion.
Cartilage does not have any vascularization - it gets all its nutrients via diffusion from the surrounding extracellular matrix.
Nutrients, oxygen, etc. diffuse from nearby blood vessels through the matrix of the cartilage to reach the chondrocytes residing in their lacunae.
Bone is far more vascular than cartilage, which means the bone receives nutrients/oxygen/other good stuff more and easier than cartilage. Cartilage has almost no blood supply, which makes healing difficult. Hope that helps..
False

The types of connective tissue are loose (ex: padding under skin), bone, cartilage, and blood. Cartilage does not directly receive a blood supply. It gets its nutrients from surrounding fluid.
hyaline cartilage A Hyaline cartilage, but lacking perichondrion
