👉 The term "ossarium" refers to a small, curved opening or sac in the ear that is connected to the outer ear and contains some of the eardrum. This opening helps protect the inner ear from foreign objects like wax and debris by allowing air to pass through while protecting the delicate structures inside. The ossaryum is also known as the "ear canal" because it's where most of the fluid in the ear comes into contact with the outside world.
