This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water â hence the name photosynthesis, from the Greek Ïá¿¶Ï, phÅs, light, and ÏÏÎ½Î¸ÎµÏÎ¹Ï, synthesis, putting together.
The human body's own cartilage is still the best material for lining knee joints. This drives efforts to develop ways of using a person's own cells to grow, or re-grow cartilage tissue to replace missing or damaged cartilage.
In each knee, there are two menisci, one on the inner side of the knee (medial meniscus), and one on the outer side of the knee (lateral meniscus). The meniscus functions to help distribute force across the joint and is important in cushioning and protecting the cartilage of the knee.
