🤖 AI Generated

When you raise your arm (especially in shoulder flexion or abduction), the coracobrachialis becomes more superficial because:

  1. The deltoid moves upward, reducing its coverage.
  2. The pectoralis major stretches, making underlying structures more apparent.
  3. The coracobrachialis is tensed, especially if there is resistance to the movement (e.g., holding an object or flexing the shoulder against resistance).
