Jointed limbs are important to arthropods to facilitate survival through mobility, feeding, sensory functions, respiration, etc. The reason for the jointing itself can be attributed to the composition of the exoskeleton (chitin); because of its rigidity, jointing is necessary to provide degrees of freedom for rotation, flexion and extension, etc., to perform physical functions; without jointing, they might be immobile. Other animal phyla might appear to have obviated the use of limbs altogether (like the annelid earthworm) or utilize an unjointed muscular limb (like cephalopod molluscs).
