Spiders, like humans have the same basic bodily systems that we do however they do not work in the same way and are also arranged differently throughout the body. In spiders what is known as the cephalothorax contains the brain, stomach, eyes, and mouth and the abdomen contains the heart, digestive tract, reproductive organs and lungs.
One of the most astounding things about spiders is that they are equipped with very small brains. However how much they can accomplish with such a small brain is almost unheard of! The spider’s central nervous system is made up of two relatively simple ganglia, or nerve cell clusters that are connected to nerves leading to the spider’s muscles and sensory systems. Some species of spiders have even exhibited learning behavior. For instance, if something isn’t working they will give up and try something new.
