movement: walking
1st joint used: 4.? joint 1st joint type: ball and socket joint
2nd joint used: knee joint 2nd joint type: hingy joint

Explanation:

For the movement of walking:

• The hip joint (1st joint) is located where the femur (thigh bone) meets the pelvis. It is a ball - and - socket synovial joint, which allows for a wide range of motion including flexion, extension, abduction, adduction, and rotation, all of which are important for the various phases of walking like lifting the leg and moving it forward.
• The knee joint (2nd joint) is found between the femur (thigh bone) and the tibia (shin bone). It is a hinge synovial joint, which primarily allows for flexion and extension. This movement is crucial for bending the leg when taking a step and straightening it to push off the ground.

Answer:

Movement: Walking
1st joint used: Hip Joint, 1st joint type: Ball - and - socket synovial joint (found where femur meets pelvis)
2nd joint used: Knee Joint, 2nd joint type: Hinge synovial joint (found between femur and tibia)
