Names of body parts are used much the same 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.
- Examples: ¡Abre los ojos! (Open your eyes!) ¡Cierre la boca! (Shut your mouth!) Él bajó la cabeza para orar. (He bowed his head to pray.)
- Examples: Me gustan tus ojos. (I like your eyes.) Acerqué mi mano a su cabeza. (I moved my hand close to his head.)
- Examples: Tengo el pelo negro. (I have black hair.) Prefiero los ojos verdes. (I prefer green eyes.)

Notes:
1. El dedo can refer to either a finger or a toe. If necessary to distinguish, you can use el dedo de la mano or el dedo del pie, respectively.
2. Mano is one of the very few Spanish nouns ending in -o that is feminine.
3. Some of these terms are used for humans but not for other animals (or not as frequently). For example, el hocico and el pescuezo are often used to refer to the nose and neck of animals, respectively.
