I was waiting for Dr. Bill to contribute a mnemonic, but I guess he's hiding. Hoping no one takes offense, there is a famous one used in medical schools to remember the endings of the facial nerve, which goes, "Oh Oh Oh to touch and feel a girl's vagina -- sex hurrah!" My wife, a registered nurse, learned a different one in nursing school which began, "On old Olympus' topmost top (I forget the rest -- it's not as memorable as the boys' version). Dr. Bill can at least tell us what the nerve endings are; I only remember ocular, trigeminal, vagus.
