No, the fingernail is distal to the elbow. Imagine a body standing with arms and legs spread out, like Da Vinci's Vitruvian Man. To determine if a part is distal or proximal to another part, look to see if it is closer or farther from the center of the body relative to the body part you are comparing it to. The fingernail is farther from the center of the body than the elbow, so it is distal to the elbow. In contrast the shoulder is closer to the center of the body, so it is proximal to the elbow. Using the same reasoning, the elbow is distal to the shoulder. When you're comfortable with those distinctions, you can start thinking about other terms like ventral, dorsal, caudal, saggital, coronal, etc.
