What type of movement primarily occurs at the hip joint?

The hip joint is a ball-and-socket type of joint, which allows for a wide range of movements. This versatility means that it can perform flexion and extension, where the leg moves forward and backward relative to the trunk. Additionally, it allows for abduction and adduction, enabling the leg to move away from and toward the midline of the body, respectively. Furthermore, the hip joint also facilitates rotation, both internal and external, providing further mobility.

Since all these types of movement—flexion, extension, abduction, adduction, and rotation—are possible at the hip joint, the correct answer encompasses all these movements, affirming that the hip joint is capable of executing all of the mentioned motions. This comprehensive functionality is crucial for various activities such as walking, running, and changes in direction, highlighting the importance of the hip joint in lower extremity movement.
