The nervous system of the arthropod is a quite simple system. Its nervous system has a dorsal brain and a ganglionated longitudinal nerve cord. This cord has lateral nerves that extend across it on each section of it. The arthropod has nerves that are located throughout the body. The arthropod has sense organs on the body surface of the exoskeleton barrier. The sensory nerve endings are found on the antennae, mouthparts, joints, and leg tips. The changes of the tensions or textures in the surrounding cuticle stimulate these nerve endings. Tensions changes in the exoskeleton are what stimulate the receptors of the arthropod. These receptors are located below the thin membrane that covers the slits in the exoskeletons on arthropods. These receptors allow the nerves to be stimulated and they may be used for different reasons. Specifically on the spider, the receptors can sense when prey is trapped. The spider’s nervous system is an example of an arthropod’s nervous system. It has many nerve cells that are located in the abdomen. The spider has a brain and its brain main function is to process sensory information, most importantly from the eyes. The spider has ganglia along its legs. The spider sensory receptors respond to touch, vibration, proprioceptor input, visual and thermal signals, and taste. The spider has hairs along its body that react to touch and vibration. The proprioceptors on the spider detect the position of the spider’s various appendages. Spiders have receptors in their eyes that allow them to see and the nerves are carried down to the spider’s brain so the image can be processed. These different forms of nerves along the spiders body is how the nervous system of the spider allows them to function properly.
