Causes of facet disease. Facet disease may arise when the cartilage in a facet joint is worn down as a result of aging, injury or wear and tear. This type of spinal damage can be attributed to arthritis, work, overuse or an injury sustained in an accident.acet disease occurs when a facet joint degenerates. While this can take place at any level of the spine, it most commonly affects the lumbar (lower spine) region. 1  Facet arthritis. 2  Facet joint syndrome. 3  Facet disease.
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Cross section of a leaf, showing the anatomical features important to the study of photosynthesis: stoma, guard cell, mesophyll cells, and vein.
Carbon Dioxide, and water are the reactants. Glucose and oxygen are the products. Just remember there are other products that are made in the process of photosynthesis, but ar â¦ e used elsewhere. An example of this is NADPH.NADPH is a product of PS1, but then is used in the Calvin Cycle.arbon dioxide and water are the two reactants, and carbohydrates (glucose) and oxygen are the end products. Sunlight is the energy source for the endothermic reaction. Along with glucose, products including ATP and other intermediary chemicals are produced.
