Planaria sp Nervous system

 Planaria sp   Nervous system

 The nervous system consists of a ganglion in the head. From each of these ganglions there is a beam of nerves that extends posteriorly towards the edges of the body. Each nerve file branched horizontally connecting the two lateral nerve files to form a nervous system of rope ladders. This ganglion can be considered as the animal's brain. The lateral nerve branches outward from the nerve cord to the muscles of the body. These nerve branches are peripheral nerves. The two nerve straps meet at the front and back ends. At the anterior end of the body there is a tool that is sensitive to light stimuli, namely a pair of eye spots.
