Detailed explanation-1: -Distal refers to sites located away from a specific area, most often the center of the body. In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist.
Detailed explanation-2: -So a finger is distal to the wrist, which is distal to the elbow, which is distal to the shoulder. Or, similarly, the femur is proximal to the knee, which is proximal to the ankle, which is proximal to the toes.
Detailed explanation-3: -The proximal phalanx of the fingers is the proximal, or first bone, in the fingers when counting from the hand to the tip of the finger. There are three phalanges in each finger. The proximal phalanx is the largest of the three bones in each finger; it has joints with the metacarpal and with the middle phalanx.
Detailed explanation-4: -Proximal means ‘closer to the origin of a structure’, like a limb, while distal means ‘farther away from the structure’s origin’. Thus, when comparing the shoulder to the elbow, the shoulder is proximal and the elbow is distal.
