After our feet we have our legs and pelvis. They are built by the hipbones, the thighbones, the shinbones and the calf of the legs. The hip joint is the joint situated between the hipbone’s socket and the thighbone’s condyle. Behind the neck of the thighbone the thighbone’s stem makes up the big thighbone’s humpback, that you can feel under the skin. The hip joint’s capsule is enforced by strong ligaments and therefor has diminished movability. The joint is, however, stable enough to balance the body weight on the lower part of the body. Below the thighs we have the knees. They have a joint between the thighbone and the shinbone. the calf of the leg lies behind the shinbone and is not part of the knee’s joint. Tje knee’s joint has a big movability when bending and stretching. Around the knee there are crescent-shaped fibrocartilaginous structure, meniscus, that enhance the fit and gives support. The meniscus can get jammed when being exposed to extreme movement in the knee joint and can, at heavy pressure from the legs, break so a piece will loosen. The loosened pieces kan shift and it will feel like the knne is jammed. There’s also ACL/Anterior cruciate ligament and PCL/Posterior cruciate ligament, which are strong ligaments. They prevent the thighbone and the shinbone to glide away from each other. If these ligaments breaks, the stability in the joint will diminish due to the lower leg can shift opposed to the thighbone. ACL and PCL can break when the knee is hit badly. There’s also ligaments on the side and the knee capsule called patella.
The pelvis is the cradle your spine rests in, so it’s important that it isn’t twisted, because that’s going to give you a back ache. Try to have a good posture. If you walk on high heals your calf is going to shorten and that will make it harder to walk effeciently. You will also have an overload of the feet. The knees will also be overloaded and the tendons around the knees will stiffen.
Tomorrow I will go through the muscles.
