What does prosencephala mean?

Prosencephala is the plural of prosencephalon, the technical term for the anterior portion of the embryonic brain, commonly called the forebrain. During development, the prosencephalon divides into the telencephalon and diencephalon; the telencephalon produces the cerebral hemispheres, while the diencephalon contributes to structures including the thalamus and hypothalamus. The plural is used in embryology and comparative anatomy when referring to the brain regions of embryos or multiple specimens. Most general readers will encounter the singular prosencephalon more often, and specialized medical or biological knowledge is usually needed to understand its developmental significance. The term is especially relevant in discussions of congenital neurological abnormalities involving the forebrain.

Etymology of prosencephala

The singular prosencephalon combines the Greek prefix pro-, meaning “forward” or “before,” with a form of Greek enkephalos, meaning “within the head.” The compound was Latinized as prosencephalon, and its established plural is prosencephala. The related terms encephalon, cephalic, and encephalic reflect the same Greek root for the brain or head.
