A plane joint (arthrodial joint, gliding joint, plane articulation) is a synovial joint which, under physiological conditions, allows only gliding movement. Plane joints permit sliding movements in the plane of articular surfaces. The opposed surfaces of the bones are flat or almost flat, with movement limited by their tight joint capsules ...
A multiaxial joint (polyaxial joint or triaxial joint) is a synovial joint that allows for several directions of movement. [9] In the human body, the shoulder and hip joints are multiaxial joints. [10] They allow the upper or lower limb to move in an anterior-posterior direction and a medial-lateral direction.
Joints are classified both structurally and functionally. [4] Joints play a vital role in the human body, contributing to movement, stability, and overall function. They are essential for mobility and flexibility, connecting bones and facilitating a wide range of motions, from simple bending and stretching to complex actions like running and ...
Regarding posture, a pronated foot is one in which the heel bone angles inward and the arch tends to collapse. Pronation is the motion of the inner and outer ball of the foot with the heel bone. [13] One is said to be "knock-kneed" if one has overly pronated feet. It flattens the arch as the foot strikes the ground in order to absorb shock when ...
Various bones of the human skeletal system. The axial skeleton , comprising the spine, chest and head, contains 80 bones. The appendicular skeleton , comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones.
Examples of a pivot joint include: Proximal radioulnar joint; Distal radioulnar joint; Median atlanto-axial joint; In contrast, spherical joints (or ball and socket joints) such as the hip joint permit rotation and all other directional movement, while pivot joints only permit rotation.
Joint pain is pain associated with one of the many joints in your body. The medical term for joint pain is arthralgia. Joints commonly affected by pain: Knee. Hip. Neck. Shoulder. Elbow. Joints of ...
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] A categoric list of movements and the muscles involved can be found at list of movements of the human body.
