Blood flow through a normal aorta and an aorta with an aortic dissection
The blood flow in a healthy aorta compared to the blood flow in an aortic dissection. In a dissection, a tear in the inner layer of the vessel causes blood to flow between the layers and form a false lumen. Depicted here is a type A aortic dissection - a dissection occurring in the ascending aorta.
A sprained ankle occurs when you roll or twist your ankle, causing the ligaments around your ankle to become damaged. This illustration depicts some of the ligaments that can be torn in a severe ankle sprain, including the anterior tibiofibular ligament anterior talofibular ligament, and calcaneofibular ligament.

Three component model of force transmission in muscles
Diagram showing the three component model of force transmission in muscles, including the parallel elastic component (PEC), series elastic component (SEC), and contractile component (CE). The contractile element is further made up of sarcomeres containing the microfilaments actin and myosin, while titin is an element of the series elastic component.
