Colored powder that gets thrown around during these races is actually cornstarch colored with FDA-approved food dye, according to the Color Run website. It states: âOur fabulous shine powder is more like make-up and is completely safe and even more precisely thrown on the lower half of your body [sic].â1. Even though the website specifies the powder goes on the lower half of the body, I am sure the cornstarch is getting inhaled as well.
Knee MRI, sagittal plane. Tha plane of imaging is just medial to the knee midline. The course of the posterior cruciate ligament is well seen, from the lateral surface of the medial femoral condyle to the posterior intercondylar area of the tibia. Note the stripe of high intensity signal between the quadriceps femoris tendon and the distal femur.
Ligaments (another type of soft tissue) lie along the sides and back of the knee, holding the bones of the knee joint in place. These ligaments work with the muscles, bones and tendons so that you can bend and straighten your knee. Fluid-filled sacs (bursae) cushion the area where skin or tendons glide across bone.The knee also has a lining (synovium) that secretes a clear liquid called synovial fluid.here are three bones in your knee joint. Your thighbone (femur) sits on top of your shinbone (tibia). When you bend or straighten your knee, the rounded end of your thighbone rolls and glides across the relatively flat upper surface of your shinbone.
