No Bones About It! Mystery Cache

If I were to write a poem about bones,
        In the zone I'd be with my poem on my own.
Maxilla, scapula, sternum and ulna,
        And can't forget radius, and a femur I'll draw ya.
With my phalanges I'll scratch my poor cranium,
        As my pelvis is pained trying to rhyme with my brainium.

So puzzled I'd be that I'd find it quite humorous,
        This little riddle about a your ribs and your humerus.
And before I finish and dance on my metatarsals,
        You'll need to think about how many metacarpals.

Yes, metacarpals is what this poem is about,
        Think of how many and this cache you'll find out,
And they'll be no bones about it,
        You'll search, sign and shout,
                        Your mandible flapping,
                                        As "I FOUND IT!" you'll tout.
