感銘を受ける ('to receive a deep impression / be deeply moved') is the formal counterpart to the everyday 感動する — heavier, more reverent, often used in speeches, biographies, and prose accounts of personal transformation. 感銘 itself is a literary noun (kanji 感 'feel' + 銘 'inscription / engraving') with the metaphor of an experience being inscribed onto one's heart. The pattern Xに感銘を受ける takes に for the trigger — the source of the impact. 献身的 ('devoted, self-sacrificing') and 奉仕 ('service, dedicated work') together evoke a high register: this is the language of medals, citations, and obituaries. 奉仕 in particular has roots in religious service before it broadened to civic and professional dedication.
