The external base of the skull (basis cranii externa) is the part of the skull that is located at the junction between the skull and the spine. It consists of two main elements: the outer surface of the base of the skull (facies externa basis cranii) and the outer base of the skull (basi cranii externae).
The outer surface of the base of the skull is a flat surface that forms the back of the skull. It is covered with skin and muscles that provide mobility to the head. Various structures are located on this surface, such as the mastoid process, mastoid groove, temporal fossa and others.
The outer cranial base is the part of the skull located between the skull and the vertebrae. It consists of several bones such as the occipital bone, the sphenoid bone and others, which form a strong frame for the skull.
The external skull base plays an important role in maintaining the stability of the head and neck. It provides support for the muscles and ligaments that are involved in the movement of the head and neck, and also protects the brain from damage.
In addition, the external base of the skull is of great importance for hearing and vision. Inside it are the hearing organs, such as the auricle and auditory ossicles, as well as the eyeballs and nerves responsible for vision. Thus, dysfunction of the base of the skull can lead to serious health problems such as hearing and vision impairment, headaches and other problems.
In general, the external skull base is an important part of the human body, which plays a key role in its functioning. Therefore, it is necessary to take care of its health and maintain its integrity to avoid possible health problems in the future.
Since ancient times, openness to knowledge and exploration of the surrounding world has prompted people to expand the boundaries of their scientific horizons and put forward original ideas in various fields of activity. Man's desire to make the world around him better is realized in various sciences; but at all times the main topic in scientific works was anatomy. This work is devoted to the natural aspects of anatomy, which unites so many areas of human knowledge such as medicine, biology and anatomy.
