The human skull consists of two main parts. Theneurocraniumor braincase is the part which encloses the brain, while theviscerocraniumis the portion that forms the facial skeleton. The skull may also be divided into calvaria (skullcap or skull vault) andcranial base(or skull base). The calvaria is the upper part of the neurocranium covering the cran...
There are also three tiny bones called the auditory ossicles. They are known as the malleus, incus, and stapes. They arelocated within each middle earhoused in the skull. Specifically, these tiny bones are found within the right and left temporal bones. The stapes is the smallest bone in the human body. As mentioned above, the skull is formed by 22...
The human skull containstwo main junction types: 1. Synarthroses or synarthrodial joints - junctions thatallow no movement; 2. Diarthroses or diarthrodial joints - joints that allow free activities. Sutures and synchondroses (cartilaginous joints) are classified as synarthrodial joints. The only joint in the skull allowing free movements is called ...
Bones of the skull provide attachment for muscles of the head and neck. The facial musclesarise from the bones of the facial skeleton. But the base of the skull serves as attachment site for the following muscle groups: 1. Masticatory muscles 2. Extrinsic muscles of the tongue 3. Superior constrictor of the pharynx 4. Muscles of the soft palate
Several bones of the skull contain air-filled spaces surrounding the nasal cavityknown as the paranasal sinuses. There arefoursets of bilateral paranasal sinuses named according to the bone they are located. All of these sinuses open into the nasal cavity and they are considered to belong to the respiratory system. The four paranasal sinuses are th...
The skull is rich with openings, including foramina (singular: foramen) andcanals that connect one anatomical structure or region with another. These openings serve primarily as passages for cranial nerves, their branches, and accompanying blood vessels (arteries and veins). Nerves and vessels form neurovascular bundles. They may be harmed at the s...
The skull is divided into several important topographical regions, including the following: 1. Cranial base 2. Temporal fossa 3. Infratemporal fossa 4. Pterygopalatine fossa 5. Orbit 6. Nasal cavity Most of these regions are formed by different cranial fossae.
The periosteum is a layer of dense connective tissue covering the surfaces of bones, and that includes the skull. The periosteum that covers the skull bones is also known as the pericranium. The periosteum has a significant role in bone repair and growth and impacts the blood supply of the bone. It consists of two layers: 1. Outer fibrous layer 2. ...
The primary function of the skull is to provide protection for the brainand the sensory organs connected with it. It also incorporates the upper part of the digestiveand respiratory tracts. The skull supports the soft tissue of the head and facial anatomical structures. The skull also provides such functions as: 1. Head movement 2. Formation of the...

Oct 30, 2023 · The skull contains all the bones of the head and is a shell for the brain and the origins of the central nervous system. A first glance shows that this is one large mass of detailed and irregular bone. Upon closer inspection however, it seems that it is intricately constructed of many smaller bone fragment pairs, all unique in shapes and sizes ...
