The invention further provides a heat machining method and heat treatment method of the medical titanium alloy, and the application of the medical titanium alloy as orthopaedic implants. The novel medical titanium alloy has the biomedical function of promoting regeneration of bones and blood vessels, ...
Bones support the body, protect underlying organs, and provide a movable skeleton against which the muscles can work. In addition, bone forms all the cells of the blood, plus takes part in calcium and acid-base balance, and storage of trace elements (such as zinc) needed by cells elsewhere...
The function of the meniscus is to cushion the knee joint and transfer forces between the tibia and femur, the thigh and shin bones. Most of the joints in our body are lined with a thin layer of articular cartilage, made of collagen and chondroitin. This provides a smooth surface over the...
Blood forms in the bone marrow, a spongy tissue contained in the bones. Red Blood Cells and Hemoglobin Only a small amount of the oxygen needed for life can dissolve directly in plasma. Oxygen transport instead relies on red blood cells. At any one time, there are more than 25 trillion...
of mesenchymal stromal cells (MSCs) from marrow, muscle, and especially the periosteum into bone-lineage cells drives the formation of callus. Finally, the dynamic balance of osteoblast and osteoclast activity remodels newly formed woven bone into lamellar bone. Bones are richly innervated by ...
The classical cascade of neutrophil recruitment has been updated recently to reflect our better understanding of how this process occurs in the blood under shear stress conditions (for example, neutrophils have been found to form tethers and slings to anchor themselves to the vasculature). In additio...
The structure of the periosteum has two distinct layers, meaning the two layers have their own structure and corresponding job. The outer layer contains nerves as well as blood vessels to help supply the skeletal muscles and bones with nutrients in the blood. The inner layer of the periost...
The testis consists of the germinal compartment (the seminiferous tubules), containing Sertoli cells, immature germ cells, and spermatozoa; and the interstitial tissue, composed of blood vessels, lymphatics, fibroblasts, mast cells, macrophages, and Leydig cells. The immunobiology of the testis is un...
DIFFERENT TYPES OF VEINS Deep Veins. These veins are found in the muscles and along the bones. The crucial task of returning oxygen-poor blood to your heart is carried out by the deep veins. The deep veins in your legs store around 90% of the blood that returns to your heart. One-way...
Themuscular systemis thebody systemresponsible for movement. The muscles are attached to bones and make up important organs, like the heart, digestive organs and blood vessels. Human body model showing some of the parts in the muscular system ...
