The pericentric aspect of the term “pericentric inversion” refers to the fact that the centromere is included in the inversion.  The centromere is basically a central part of a chromosome that links sister chromatids and where the spindle fibers attach to break apart the sister chromatids in mitosis.  Alternatively, paracentric inversion means that the centromere is not involved in the inversion.

I found that factoid really interesting, since it’s mutations that drive evolution.  With the obvious similarities, it’s neat to see exactly what mutation took place where.

To be clear, that’s not the only difference between chimps and people. That’s the only difference on that particular chromosome, though.
