1. Hip, 2. Leg, 3. Knee, 4. Carpal.

Explanation:

1. Hip: The shoulder and hip joints are both enarthrosis, this is a type of mobile joints formed by a head that fits into a cavity and moves in every way: backward, forward, sideways and makes rotational movements.

2. Leg: The arm and the leg are both extremities formed by long bones. Leg: the proximal bone (closest to the body) is femur, that is equivalent in form and  function to the humerus in the arm. The other pair of bones forming the leg are: tibia and fibula, that are equivalent in form and function to the radius and ulna in the arm.

3. Knee: Knee and elbow are part of the hinge or trochlear joints type. This means that they have the function of extension and flexion. They also are in the middle of the long bones described above, making the movements of the knee and elbow.

4. Carpal bones: like tarsal bones, they are classified as sliding joints. The main characteristic is that the joint surface is flat, and also, allows movements to the sides and from back to front or viceversa. They are surrounded by ligaments and other bones that restrict other movements.
