In addition to stem cells, which are well-known players, many animal studies of tissue regeneration have suggested the important roles of peripheral nerves in the regeneration of various tissues. Peripheral nerves can be functionally divided into three categories: the autonomic nervous system (ANS), ...
• Vitamin C is an antioxidant vitamin needed for the formation of collagen to hold the cells together and for healthy teeth,gums and blood vessels; improves iron absorption and resistance to infection.Vc是一种促进(骨)胶原合成的抗氧化维他命,有益牙齿、牙床及血管;促进铁的吸收并抵抗感染.Vitamin...
In its interior, bony tissue is arranged in a network of intersecting plates and spicules called trabeculae, which vary in amount in different bones and enclose spaces filled with blood vessels and marrow. This honeycombed bone is termed cancellous or trabecular. In mature bone, trabeculae are ...
Bone development and bone remodelling during adult life are highly anabolic processes requiring an adequate supply of oxygen and nutrients. Bone-forming osteoblasts and bone-resorbing osteoclasts interact closely to preserve bone mass and architecture and are often located close to blood vessels. Chondrocy...
Joints can be classified in two ways: temporally and structurally. Each classification is associated with joint function. Considered temporally, joints are eithertransientor permanent. Thebonesof a transient joint fuse together sooner or later, but always after birth. All the joints of theskull, for...
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...
The knee meniscus is a special layer of cartilage that lines the knee joint. The job 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 ...
