Publisher: MEDCoE
Explore how the human nervous system receives and processes information in this free online course on sense organs. You will learn about our senses of vision, hearing, balance, smell and taste. After completing this course, you will be able to describe the structure and functions of organs like our eyes and ears and identify the sensory receptors in our nose, mouth and skin. This will be a useful addition to your knowledge of human anatomy.

The human nervous system performs the critical task of keeping our body healthy and safe. It receives and processes information about the external environment to react and communicate with the body parts and organs. Who provides this information to the nervous system? You will find the answer to this question and more in this course on sense organs. We have known about the five sense organs and senses for thousands of years. The first module will explain the need for senses in the human body and describe the differences between general and special senses. The receptors for general senses run throughout the body, while for special senses, specific organs act as receptors. The eye is one such organ that starts working from the moment you wake up as it receives tons of information. You will learn how the eye translates light into image signals, which are then processed by our brain.

Next, you will learn about the organ that helps us to enjoy the pleasures of music and laughter or even react to honking. It is the ear, which uses bones and fluid to transform sound waves into sound signals. You will be introduced to the sense of hearing. Did you know that the ear plays an important role in keeping your balance? The special reflexes of the human nervous system will be discussed during this course including which part of your brain coordinates them. Our brain also interprets the signals stimulated by the chemicals in the air and this is how we cherish fragrances and aromas. It is our nose that receives the sense of smell. You will know more about the nose and our nasal chamber as you progress through the course.

Finally, if you have ever wondered about those small bumps on the top of your tongue, then in this course you will be able to decipher the science of the tongue, which is the home of the taste buds. Have you ever wondered how do we taste things? You will learn which nerves have a role in interpreting the sense of taste and in which part of the brain does this interpretation take place. This course will be of great interest to the students of biology or medical sciences as well as to the enthusiasts of human anatomy as you demystify the words like epiglottis, larynx, cerumen and tympanic membrane. You will gain the basic information to pursue a career in healthcare or pharmaceutical industry. People with specialised knowledge of anatomy also work in government agencies or scientific publishing firms. So, this could be a stepping stone to your dream career.
