Etymology: Cephalically is built from "cephalic," which comes from Greek "kephalē," meaning "head," plus the adverbial ending "-ally." The Greek root turns up in many scientific terms, from "cephalopod" (a head-footed mollusc like the octopus) to "encephalitis" (inflammation within the head). English adopted "cephalic" as a technical anatomical term in the 19th century, when physicians and naturalists were naming parts of the body and animal structures from Greek and Latin roots. The adverb follows the same pattern. English often forms adverbs from adjectives ending in "-ic" by adding "-ally," so "cephalic" becomes "cephalically" when describing how something is positioned or oriented in relation to the head. A biologist might say a sensory organ is located cephalically, meaning toward the head end of the body, or that a development proceeds cephalically, from the head end backward.
