Anatomy of the Posterior Upper Thigh

hamstring muscles

 The upper leg muscles provide your knees with mobility and strength. A group of these musles are called hamstring muscles (posterior thigh muscles). The hamstring muscles are located on the back of your thigh. They work closely with your leg’s other muscles to ensure proper movement of your leg and hip.
  Your hamstring muscles control movement of your body, hip and knee, help turn your leg in and out, and are involved with power activities that include a lot of propulsion, thrust and control (such as jumping, running, and walking). They are involved with eccentric movements, which increase the length of the muscle while it is under tension – instead of starting an action, the muscles act as a brake to stop an action. You can feel this when walking or running downhill, landing from jumps or performing squats, and when trying to stop quickly after sprinting.
  The hamstrings are made up of 3 long muscles that start at the bottom of your pelvis extending down the back of your thigh and along either side of your knee, to your shin bones. The lateral hamstring is the biceps femoris, and the medial hamstrings are the semitendinosus and the semimembranosus.The tendons (tough fibers that connect muscle to bone) for these muscles help to stabilize your knee.
