[Campbell Biology P.1183] Which of the following statements accurately describe the types of ... | Practice Question

Which of the following statements accurately describe the types of joints and their movements as presented in Figure 50.38? Select all that apply

  • A: Ball-and-socket joints, like the one found at the shoulder, allow rotation and movement in several planes.
  • B: Hinge joints, such as the elbow, restrict movement to a single plane.
  • C: Pivot joints enable rotating the forearm at the elbow and turning the head from side to side.
  • D: The hip joint is an example of a hinge joint.

Explanation

Figure 50.38 and its accompanying text clearly define these joint types. Ball-and-socket joints e.g., shoulder, hip allow multi-plane movement and rotation. Hinge joints e.g., elbow restrict movement to a single plane. Pivot joints e.g., forearm, neck enable rotation.
