Biological Basis of Behaviour MR2204 J Mulvany Sensory Systems Georgina Meek 7th November 2014 Introduction Great Grey Owls (Strix nebulosa), use a wide variety of different environmental factors when hunting a lemming (Lemmus sp.) when it is hidden beneath the snow. The different sensory systems which the owl possesses are particularly adjusted in order for the owl to most suitably use them to the best of its ability when hunting. The various sensory systems refer to the way in which the nervous system receives information from the external environment (exterocepton), internal environment (interoception, and the position and movement of the bod of the animal (proprioception). Once the body is given this sensory information, it is used to generate what the animal’s next move will be. Animals need these sensory systems in order to have an understanding of what is going on within their body and what is happening in the surrounding environment, Stevens (2013). All animals have adapted in different ways, with different body parts which are attuned to that animal’s habitat. These body parts which are sensitive to different stimuli act as a filter which detect and respond to stimuli, and ignore others. These body receptors interpret and convert the type of energy, whether it is light, sound, or smell, and turn it into an electrical signal to be interpreted by the central nervous system. Each animal’s physical make up is attuned to provide the greatest survival
