Types of Joints: Hinge and Ball-and-Socket
- Skeletal movements are facilitated by muscle action at joints or articulations, where bones meet. These joints, such as ball and socket joints like hips and shoulders, allow for universal movement in all directions and twisting of the ball, enabling a wide range of motion for limbs like arms and legs.
- Another type of joint is the hinge joint, seen in areas like knees and elbows, which allows for simple movement in one direction. This joint is exemplified by the knee joint, showcasing a basic form of movement below the joint.
