Notes
change- ↑ According to most dictionaries, the word sphenoid (/ˈsfiːnɔɪd/[1][2] derives from Greek sphenoeides, "wedgelike". Thieme Atlas of Anatomy[3] disagrees and says that the sphenoid bone was originally called os sphecoidale, meaning "bone resembling a wasp", and that the word was later written 'sphenoidale' by a transcription error. An anterior view of the bone resembles more the body of a wasp or a bat[4] with wings than a wedge.
