WebbThe nervous system consists of two parts, shown in Figure 1: The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system (PNS) consists of nerves outside the CNS. Nerves of the PNS are classified in three ways. First, PNS nerves are classified by how they are connected to the CNS. Sharks have a complex electro-sensory system. Enabled by receptors covering the head and snout area. These receptors sit in jelly-filled sensory organs called the ampullae of Lorenzini. These tiny pores are extremely sensitive and can detect even the faintest of electrical fields. Such as those generated by the … Visa mer Up to two thirds of the total weight of a shark's brain is dedicated to smell. They’re super-sensitive to smells that are important to their survival.
