Components of a synovial joint are: Fibrous articular capsule (or joint capsule)‚ which surrounds the joint Articular cartilages‚ which resemble hyaline cartilages and cover the articulating bone surfaces Synovial fluid‚ which is located within the joint cavity and provides lubrication‚ distributes nutrients‚ and absorbs shocks 8.2 (a) Identify the types of synovial joints based on the shapes of the articulating

is fluid contained within specialized cavities of the body and is also considered to be part of the ECF. Examples of trancellular fluid include: * Cerebral Spinal Fluid * Pericardial Fluid * Pleural Fluid * Synovial Fluid * Intraocular Fluid * Digestive Secretions Intracellular Fluid (ICF) – This is the fluid that is contained within the cell. In adults it is approximately 2/3’s of the body’s fluid (27 liters). The ICF also known as “cellular

Effects of curing condition of solution cast Nafion® membranes on PEMFC performance Korean J. Chem. Eng.26(3)‚ 679-684 (2009) Thickness of membrane ~ 50µm There are some disadvantages of the solution casting method that the cold cast films are generally mechanically weak‚ susceptible to crack formation and soluble in many polar solvents‚ especially in water at room temperature. Generally‚ the annealed films undergo morphological changes when heated above the glass transition temperature (Tg=109oC

that course between septa‚ and small tendons have almost no vascularity. Tendons can attach to tuberosities‚ processes‚ or ridges. Synovial sheaths are double walled cylinder shaped structures the surround some tendons. Small amounts of synovial fluid can be found within these sheaths to act as a lubricant for the moving tendons. Large tendons do not contain synovial fluid. Tendons appear hyperechoic to surrounding anatomy on ultrasound. Sonography can be performed on tendons of the shoulder‚ elbow

was to see how easily molecules of smaller diameter‚ which were starch molecules‚ would pass through an artificial membrane‚ as opposed to how difficult it would be to pass through in the case of larger molecules‚ which were IKI molecules. Results were that the smaller substance passed though the membrane easily and rather quickly‚ and the larger substance did not penetrate the membrane whatsoever. Part III of the lab was to view the effect of molecular size on the rate of diffusion. Two substances

affecting the movement of water through osmosis Introduction In this I will be investigating what effects the movement of water through osmosis. Osmosis is the diffusion of water. It is the process in which fluids pass through a partially-permeable membrane. It is the movement of water from high water concentration to low water concentration. Plant cells react to osmosis by hypertonic‚ isotonic and hypotonic. Keywords Hypertonic – is when the water outside of the cell is lower than that inside

Diffusion of Ammonium hydroxide with red litmus paper Definition of diffusion 1. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out. 2 Diagram. 3. During the diffusion tube experiment I noted that firstly ammonium hydroxide was placed on to a piece of cotton wool. The cotton wool (with the ammonium hydroxide) was then placed in to a diffusion tube containing around 10 pieces of curled red

Children can get arthritis just like adults. Arthritis is caused by inflammation of joints. It can cause pain‚ swelling‚ stiffness‚ and loss of motion. Juvenile Arthritis is a disease in which there is inflammation of the synovium in children 15 or younger. It has several different names associated with it. Fluid is released in the joint‚ which causes the lining of the joints to swell. It makes it extremely difficult for teens to live an active life due to painful‚ swollen‚ and stiff joints. Juvenile
