INTRODUCTION

• Aesthesiology deals with the description of the sense organs which receive external stimuli and conduct impulses to the brain which result in sensations of sight, hearing, taste, smell, touch, pain, temperature and pressure.
• These sensations are received and transmitted as nerve impulses to the central nervous system by receptors, which may be specialized structural modifications of the dendrites or peripheral processes of usually bipolar neurons (eye, olfactory mucous membrane, skin etc.) or may be specialized “neuroepithelial cells” which are modified epithelial cells, around the bases of which are terminations of peripheral processes of nerve cells located in sensory ganglia (internal ear, taste buds).
