The muscles of the sand scorpion are striated, segmented and consist of individual muscle fibers that are intertwined with neurons. The contraction speed of the muscles depend mostly on the scorpion's impulse, and has either fast neurons for rapid movement or slow neurons to help it keep balance and for slow walking. The scorpion has 4 pairs of segmented legs, the muscles for which are fine in order to enable swift movement across the dessert sand. Furthermore, the scorpions claw, thought to have evolved from its predecessors' thick, short legs, is controlled by antagonistic (open and close) muscles for which the closing muscle is separated into a long and short closing muscle (used for catching and piercing prey).
The abdomen of the scorpion is separated into seven segments, the second segment of which contains the pectoral muscles which expand and retract according to how the scorpion breathes and moves. Lastly, the tail muscles are separated into five segments, the last of which contains a vacuole that has the venom sack, and the muscles contract to sting prey due to the neurotic impulses mentioned earlier and it makes the sting extremely quick.
