Raynaud's Disease in the context of vibration causes trauma to which structures?

Explanation:
In vibration-related Raynaud’s phenomenon, the main injury affects the small vessels and nerve endings in the fingertips. Repetitive vibration causes microtrauma to the endothelium and smooth muscle of arterioles, leading to endothelial dysfunction, vasospasm, and reduced blood flow that produces the characteristic color changes and sensory symptoms. Nerve endings in the digits can also be damaged by the mechanical stress, contributing to sensory disturbances. Muscles, bones, and lymph nodes are not the primary targets of this vibration-induced trauma, so the best answer centers on arterioles and nerve endings.
