Little Miss Muffet did not Vote for Jack Horner

Little Miss Muffet sat on her tuffet, eating her curds and whey. Along came a spider who sat down beside her, and frightened Miss Muffet away. Meanwhile, Little Jack Horner was eating a Christmas pie. He put in his thumb, and pulled out a plum, and said “what a good boy am I.”  But Jack was not a good boy – he became a greedy politician and would always have his hand in the till. He enriched himself and would spend his days carousing about, smoking premium cigars, and drinking himself silly each evening. Miss Muffet detested him and refused to endorse his candidacy in his latest race for Mayor. Fortunately for all, no-longer - little Jack developed an aneurysm at the indicated structure and while the aneurysm grew, it was remarked upon that he became hoarse. What nerve was most likely impinged by the aneurysm?

Aneurysm at indicated location most likely impinges on what nerve?
