- Discuss the structures that contribute to support of the shoulder joint.arrow_forwardWatch this video (http://openstaxcollege.org/l/flexext) to learn more about the flexion and extension of the knee, as the femur both rolls and glides on the tibia to maintain stable contact between the bones in all knee positions. The patella glides along a groove on the anterior side of the distal femur. The collateral ligaments on the sides of the knee become tight in the fully extended position to help stabilize the knee. The posterior cruciate ligament supports the knee when flexed and the anterior cruciate ligament becomes tight when the knee comes into full extension to resist hyperextension. What are the ligaments that support the knee joint?arrow_forwardA high ankle sprain iis an injury caused by over stretching the ligaments connecting the tibia and fibula. What type of joint iis involved in this sprain? ball and socket gomphosis syndesmosis symphysisarrow_forward
- Watch this video (http://openstaxcollege.org/l/anklejoint3) to learn about the ligaments of the ankle joint, ankle sprains, and treatment. During an inversion ankle sprain injury, all three ligaments that resist excessive inversion of the foot may be injured. What is the sequence in which these three ligaments are injured?arrow_forwardVisit this site (http://openstaxcollege.org/l/kneesurgery) to perform a virtual knee replacement surgery. The prosthetic knee components must be properly aligned to function properly. How is this alignment ensured?arrow_forwardWhich statement is tine concerning the knee joint? The lateral meniscus is an intrinsic ligament located on the lateral side of the knee joint. Hyperextension is resisted by the posterior cruciate ligament. The anterior cruciate ligament supports the knee when it is flexed and weight bearing. The medial meniscus is attached to the tibial collateral ligament.arrow_forward
