Sarculation is a word used in anatomy that refers to the arrangement of muscle fibers in a particular area of the body. It is pronounced /sɑːrkjʊˈleɪʃən/ and spelled with the letter "s" rather than the more commonly seen "c" in words that contain the suffix "-culum." The reason for the spelling choice is due to the Latin roots of the word, in which the letter "s" is used instead of "c." Proper spelling of anatomical terms is important for accurate communication in the medical field.
