"Cephalochordata" Natural Recordings by Native Speakers
The Cephalochordata are a group of aquatic animals that are closely related to vertebrates. They are characterized by having a notochord, a dorsal hollow nerve cord, and pharyngeal slits, but they do not have a bony skeleton or a cranium. They are found in the ocean and belong to the subphylum of vertebrates.
Cephalocercal refers to the development of the brain and spinal cord in a fetus, from the early stages of embryonic development to the point where the brain takes on its final form.
Cephalodynia is a rare and little-known medical condition characterized by chronic, severe pain in the head, neck, and/or scalp. The word is derived from the Greek words "kephale," meaning head, and "odyne," meaning pain.
