Document Summary
Factors affecting contact and range of motion at synovial joints. Refers to range, measured in degrees of a circle, through which the bones of a. The following factures contribute to keeping the articular surfaces in contact and affect joint can be moved range of motion: Structure or shape of the articulating bones. Determines how closely they can fit together. The articulating surfaces of some bones have a complementary relationship. This spatial relationship is very obvious at the hip joint, where the head of the femur articulates with the acetabulum of the hip bone. Strength and tension of the joint ligaments. The different components of a fibrous capsule are tense or taut only when the joint is in certain positions. Tense ligaments not only restrict the range of motion but also direct the movement of the articulating bones with respect to each other.
