In humans, the erector spinae, the transversospinal muscles (including the multifidus, semispinalis and rotatores), the splenius and suboccipital muscles are the only epaxial muscles, The hypaxial muscles are located on the lower side of the body, often below the horizontal septum in many species (primarily fish and amphibians). In amniotes, the positional distinctions have been lost as the body's muscles have changed through evolution, but in all species, the hypaxial muscles are innervated by the ventral ramus of the spinal nerves, while the epaxial muscles are innervated by the dorsal ramus.
