It is the lumpy bit you can feel behind your ear. One part of the temporal bone is called the mastoid bone. The temporal bone is part of the skull above the ear. The ear canal, middle ear and inner ear are all within the temporal bone. The bone that surrounds the ear is called the temporal bone. The inner ear also has a number of fluid filled cavities which help us to balance.
It converts the vibrations from the middle ear into nerve impulses which then travel to the brain. The cochlea has lots of tiny hair-like nerves on it. It also contains a small spiral tube called the cochlea. These pass on the vibrations from the eardrum to the inner ear. The middle ear is a small cavity that contains 3 small bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes). It is part of the outer ear, but the stages, symptoms, and treatment of ear canal cancer are different to other cancers of the outer ear. The ear canal is the passage running from the outer ear to the middle ear. The eardrum vibrates when a sound is made. It protects the rest of the ear and helps us collect sound. The outer ear is the part of the ear we can see. The earĪnother important part is the bone that surrounds and protects the ear (the temporal bone).
#Functional anatomy of the ear practice questions skin#
Between 6 and 10 out of 100 skin cancers (between 6 and 10%) develop on the outer ear.Ĭancers that develop inside the ear (the middle and inner ear) are rare. Most of these cancers start in the skin of the outer ear. Ear cancer is when abnormal cells in the ear start to grow and divide in an uncontrolled way.
