Correcto

• 神经检查时，观察手掌感觉和精细动作，可初步判断周围神经损伤。(In neurological exams, observing palm sensation and fine motor skills can help initially assess peripheral nerve damage.)
• 研究表明，手掌向上的手势常表示开放或请求，向下则更显控制感。(Studies show that palm-up gestures often signal openness or a request, while palm-down gestures suggest more control.)

Incorrecto

• 手掌 when referring to the back of the hand — use 手背 (back of the hand); 手掌 specifically refers to the inner, palm-facing surface; confusing the two can cause ambiguity in medical descriptions or physical instructions
