Anatomy of the inner ear

As I mentioned during my post on the anatomy of the outer and middle ears, I would be following up with a post on the anatomy of the inner ear. So today I will just try to give a bit of a summary on how the cochlea converts the vibrations of sound, to a message that can be interpreted by the brain.

The cochlea is like a long tube folded in half, and then coiled up with the folded end being the apex of the coil. This tube is filled with a fluid called perilymph. Continue reading

Anatomy of the external and middle ear

Recently I began studying my current university degree which is a Masters in Clinical Audiology. To be honest, I hadn’t really known much about the ear before I began, but since starting, I have learnt so much and thought about so many things that I hadn’t even considered before. How can we tell where sounds come from? What is a ‘sound’? How does the brain use the information a sound brings? I’ll probably end up writing more about the ear and concepts related to audiology more than anything else from now on so I apologise in advance if this is not of interest to any of our current readers. This post will be a bit of an introductory one to the anatomy of the ear. Hopefully, what I write makes sense even if you don’t have any background knowledge!

The Human Skeletal System

The skeletal system includes bone and cartilage. In an adult human, there are approximately 206 bones and these have the functions of supporting the body and muscles, protecting and enclosing visceral organs, helping us to move, making blood, and providing a place to store minerals and salts. The skeletal system is clearly absolutely essential for us to survive, so what are its components and how do they work? Continue reading
