Pronation at the forearm is a rotational movement at the radioulnar joint, or of the foot at the subtalar and talocalcaneonavicular joints. [ 11 ] [ 12 ] For the forearm, when standing in the anatomical position , pronation will move the palm of the hand from an anterior-facing position to a posterior-facing position without an associated ...
The different parts of the object do not move the same distance. Examples include a movement of the knee, where the lower leg changes angle compared to the femur, or movements of the ankle. [2] The study of movement in the human body is known as kinesiology. [4]
The lateral meniscus is grooved laterally for the tendon of the popliteus, which separates it from the fibular collateral ligament.. Its anterior end is attached in front of the intercondyloid eminence of the tibia, lateral to, and behind, the anterior cruciate ligament, with which it blends; the posterior end is attached behind the intercondyloid eminence of the tibia and in front of the ...
In humans, they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; [2] in other animals they may be present in other joints. Generally, the term "meniscus" is used to refer to the cartilage of the knee , either to the lateral or medial meniscus .
It is especially called into action at the beginning of the act of bending the knee, in as much as it produces the slight inward rotation of the tibia, which is essential in the early stage of this movement.

The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
The Jendrassik maneuver to reinforce knee-jerk. The Jendrassik maneuver is a medical maneuver wherein the patient clenches the teeth, flexes both sets of fingers into a hook-like form, and interlocks those sets of fingers together. The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex. The elicited ...
