Question

7 which of the following correctly describes a condyloid joint? a. one bone fits into a concave articular surface of another bone. b. one bone rotates around another bone. c. the flat articular surfaces of two bones glide past one another. d. the rounded, ball - like end of one bone fits into a concave depression of another bone. 8 label the following parts of the knee joint in figure 9.10. anterior cruciate ligament fibular collateral ligament joint cavity lateral meniscus medial meniscus quadriceps femoris tendon patellar ligament posterior cruciate ligament

Explanation:

A condyloid joint is characterized by one bone fitting into a concave articular surface of another bone. For the knee - joint labeling, it requires knowledge of the anatomical location of each structure. Since the figure is not provided in a way that can be directly interacted with, we can only provide general knowledge about the location of knee - joint structures. The anterior cruciate ligament is located in the center of the knee joint, preventing forward movement of the tibia. The fibular collateral ligament is on the outer side of the knee. The joint cavity is the space between the articulating bones. The lateral meniscus is on the outer side between the femur and tibia. The medial meniscus is on the inner side between the femur and tibia. The quadriceps femoris tendon is at the front, connecting the quadriceps muscle to the patella. The patellar ligament connects the patella to the tibia. The posterior cruciate ligament is in the center of the knee joint, preventing backward movement of the tibia.

Answer:

1. a. One bone fits into a concave articular surface of another bone.
2. Without the actual ability to label on the figure:

• Anterior cruciate ligament: Center of knee joint, prevents forward tibial movement.
• Fibular collateral ligament: Outer side of the knee.
• Joint cavity: Space between articulating bones.
• Lateral meniscus: Outer side between femur and tibia.
• Medial meniscus: Inner side between femur and tibia.
• Quadriceps femoris tendon: Front, connects quadriceps to patella.
• Patellar ligament: Connects patella to tibia.
• Posterior cruciate ligament: Center of knee joint, prevents backward tibial movement.
