13.1- Structure and Function of the Knees Quiz Please sign up for the course before taking this quiz. Select the statement that is accurate with regard to the bones in the illustration.1The Knee 1 The femur is "G"' the patella is "B", the tibia is "A", and the fibula is "H". The femur is "A"' the patella is "B", the tibia is "F", and the fibula is "C". The femur is "A"' the patella is "B", the tibia is "G", and the fibula is "H". The femur is "A"' the patella is "B", the tibia is "H", and the fibula is "G". Select the statement that is accurate with regard to the connective tissue in this illustration.1The Knee 1 The ACL is "D", the PCL is "E", the MCL is "F", the LCL is "C", the menisci are partially visible, but not labeled. The ACL is "D", the PCL is "E", the MCL is "C", the LCL is "F", the meniscus is "B". The ACL and PCL are visible but not labeled, , the MCL is "F", the LCL is "C", the menisci are "D" and "E". The ACL is "D", the PCL is "E", the MCL is "C", the LCL is "F", the menisci are partially visible, but not labeled. Select the statement that is accurate with regard to the bones in this illustration:1The Knee 1 The point of view in this illustration is of the posterior skeleton. The medial side of the leg is on the left side of the image. This is the skeleton's right leg. The point of view in this illustration is of the anterior skeleton. The medial side of the leg is on the right side of the image. This is the skeleton's right leg. The point of view in this illustration is of the anterior skeleton. The medial side of the leg is on the left side of the image. This is the skeleton's left leg. The point of view in this illustration is of the anterior skeleton. The medial side of the leg is on the left side of the image. It cannot be determined whether this is the left or right leg without more information. The point of view in this illustration is of the anterior skeleton. The lateral side of the leg is on the left side of the image. This is the skeleton's right leg. Select the statement that is accurate with regard to the movements, positions, muscle groups, and muscle roles with regard to the bones labeled in this illustration:1The Knee 1 When muscular contraction initiates movement that brings the posterior surface of Bone "A" closer to the posterior surfaces of bones "G" and "H', the movement is called extension of the knee joint. When muscular contraction initiates movement that brings the anterior surface of Bone "A" closer to the anterior surfaces of bones "G" and "H', the movement is called extension of the knee joint. When gravity initiates movement that brings the posterior surface of Bone "G" and "H" away from the posterior surfaces of bones "A', the movement is called flexion of the knee joint. When gravity initiates movement that brings the anterior surface of Bone "A" closer to the anterior surfaces of bones "G" and "H', the movement is called flexion of the knee joint. Select the statement that is accurate with regard to the movements, positions, muscle groups, and muscle roles with regard to the bones labeled in this illustration.1The Knee 1 When muscular contraction initiates movement that brings the posterior surface of Bone "A" closer to the posterior surfaces of bones "G" and "H', the muscles that can initiate knee extension are behaving as agonists. When muscular contraction initiates movement that brings the posterior surface of Bone "A" closer to the posterior surfaces of bones "G" and "H', the muscles that can initiate knee extension are behaving as antagonists. Whenever the posterior surface of Bone "A" comes closer to the posterior surfaces of bones "G" and "H', the muscles that can initiate knee flexion are behaving as antagonists. When muscular contraction initiates movement that brings the posterior surface of Bone "A" closer to the posterior surfaces of bones "G" and "H', the muscles that can initiate knee flexion are behaving as antagonists. The main movements that the MCL and LCL are meant to help prevent are:1 Lateral and medial displacement Flexion and extension Anterior and posterior displacement Hyperextension Rotation The main movements that the ACL and PCL are meant to help prevent are:1 Anterior and posterior displacement Rotation Extension Lateral and medial displacement Flexion and extension
