Grammar of Body Parts
Most of these words are used for the body parts of animals as well as people. However, there are a few exceptions. For instance, el hocico and el pescuezo are terms often used to refer to the nose and neck of animals. The names of body parts are used much the same as they are in Spanish as in English, but with one significant difference. In Spanish, names of parts of the body are frequently preceded by the definite article (el, la, los or las, meaning "the") instead of possessive adjectives (such as mi for "my" and tu for "your"). In most cases, the possessive adjective is used only where the context doesn't make clear whose body is being referred to. For example: ¡Abre los ojos! (Open your eyes!) ¡Cierre la boca! (Shut your mouth!) Él bajó la cabeza para orar. (He bowed his head to pray.) The possessive adjective is used when needed to avoid ambiguity. Me gustan tus ojos. (I like your eyes.) Acerqué mi mano a su cabeza. (I moved my hand close to his head.) Although English often omits the definite article when referring to body parts, they are usually retained in Spanish when a possessive adjective is not used. Tengo el pelo negro. (I have black hair.) Prefiero los ojos verdes. (I prefer green eyes.)
English Words Related to Spanish Names of Body Parts
Several of the Spanish words in the list above come from the same Latin root as English words that aren't used directly for body parts. You can use some of these connections to help you remember the words: "To embrace," embrazar in Spanish, means literally to enclose someone or something with arms (brazos). Something cerebral (related to cerebro) requires use of your brain. You use the auditory (related to oído) capability of your ear to hear. "Ocular" things are related to the eye (ojo). Our word "gargantuan" comes from a fictional character who used his throat (garganta) by eating a lot. To do something by hand (mano) is to do it manually. Something that goes under your tongue (lengua) is sublingual. Also, both lengua and "tongue" can refer to a language.
