Body parts like human hands, feet, ears, eyes, etc. exist on either side of the human body's sagittal plane and can therefore be specified with the adjectives left and right. Is there a special adjective I can use to describe body parts like this that a creature has a left and a right one of? Sentence with desired usage: Hands, feet, eyes, and ears are all ____ body parts.
I need this adjective to not apply to body parts like noses, stomachs, lips, lymph nodes, etc. that a creature either has one of, has more than two of, or has precisely two of but it wouldn't make sense to call one the left and the other the right (e.g. lips).
I'm specifically looking for an adjective to describe body parts that I could say "this creature has a left ___ and a right ___" for.
