How it works
Two views share the names: the brain from the side, with its four lobes, and the brain cut down the middle, from el cuerpo calloso to el bulbo raquídeo. Each name carries el or la.

The brainstem, top to bottom
El tronco encefálico has three parts. From the top down they are el mesencéfalo, also called el cerebro medio, then la protuberancia, then el bulbo raquídeo. MedlinePlus en español calls the whole stem el tallo cerebral.
Surco or cisura
A groove of the brain is un surco. The two on this drawing also keep traditional names with cisura: el surco central is la cisura de Rolando, and el surco lateral is la cisura de Silvio.
Only three of the 17 names are feminine: la amígdala, la hipófisis and la protuberancia.
Questions and answers
How do you say brain in Spanish?
El cerebro, in everyday Spanish. In anatomy the whole organ inside the skull is el encéfalo, and el cerebro is its largest part, the cerebrum: that is how the U.S. National Cancer Institute's Spanish dictionary defines the two words.
What are the lobes of the brain in Spanish?
El lóbulo frontal, el lóbulo parietal, el lóbulo temporal and el lóbulo occipital. The four adjectives are spelled as in English, and each lobe is masculine.
How do you say pituitary gland in Spanish?
La hipófisis, a feminine noun whose plural is the same. La glándula pituitaria is also used; WordReference notes that it is the older name and that hipófisis is preferred today.
What is the medulla oblongata called in Spanish?
El bulbo raquídeo. WordReference gives la médula oblonga as a second name. La médula espinal is another part, the spinal cord.
Where were the Spanish names checked?
Each name and its gender in WordReference and in SpanishDict or the Cambridge Spanish-English dictionary, then in the Spanish dictionary of the U.S. National Cancer Institute, MedlinePlus en español or the medical dictionary of the Clínica Universidad de Navarra.
