Forming the lateral-inferior region of the skull, the temporal bone is an even and symmetrical bone. Because of its position, this bone protects the temporal lobe of the brain and the ear. Also, it contributes to the development of the temporomandibular joint.
In the temporal bone, the scaly portion represents the largest bone section. It performs a number of functions, including:
The following muscles are related to the temporal bone:
The cranial sutures are fibrous joints that join the skull's bones together. Together with the temporomandibular joints, they are located within the temporal bone.
There are five sutures in the temporal bone, namely:
On the other hand, the temporomandibular joint allows opening, closing, and movement of the mouth, such as during chewing.
The ligaments that attach to the temporal bone are:
In terms of the nervous system, the temporal bone is associated with:
The following vessels are connected to the temporal bone:
What is the purpose of the temporal bone? Among its many functions, it is primarily responsible for protecting the temporal lobe of the brain as well as the cranial nerves. In addition to forming the external auditory canal, the temporal bone houses the cockles, canals, and hearing organs. It also protects the middle and inner ear structures, which are more delicate.
The temporal bone can be fractured just like any other bone in our body. Broken bones can cause pain in the right or left temporal bone, but other symptoms can also occur, such as dizziness and facial paralysis. Additionally, certain medical conditions can affect the temporal bone. For example, Paget’s disease of bone, a chronic disorder that disrupts the normal bone remodeling process, can lead to abnormal thickening or weakening of the temporal bone. This may result in symptoms such as hearing loss or cranial nerve compression. Moreover, an infection of the mastoid cells, known as mastoiditis, or a tumor can develop.
