Which of the following muscles is different from others? The quadratus plantae (QP) muscle is located in the second layer of the plantar musculature and consists of two heads separated by the long plantar ligament. They can be considered as part of the central plantar muscle group with the flexor digitorum brevis, quadratus plantae, lumbricals and dorsal interossei. A Review of the Function of the Quadratus Plantae by Thomas P.
