Skull

The skull forms a very important part of our body. It is an important safeguard for our brain and senses. Major construction unit consists of bones, muscles, blood supply to part of the brain and face, as well as the nerves that allow us to respond to external stimuli. The skull is a frequent target of injuries when a small shock can cause serious brain damage, plus permanent dysfunction. Therefore, you need a skull and head of generally protect.

Dividing bones

The skeleton of the skull is formed by a plurality of bones, which are, with the exception of the lower jaw, connected with each other.

Facial

  • The upper jaw (maxilla) – consists of a body and projections. Projections are for example the upper floor and beds for teeth. In the body cavity is large – the largest is the nasal cavity.
  • Cheek bone (os zygomaticum) – located below the eye, its temporal projection is associated with facial projection and form the zygomatic arch.
  • Storey bone (os palatinum) – forms the posterior part of the nasal cavity and the hard palate and resembles the shape of the letter L.
  • Hyoid bone (os hyoideum) – horseshoe small bone, which is located between the lower jaw and larynx ground and penetrated into the neck muscles.

Skull

  • Cranial vault (Kalva) – bone occipital, parietal and frontal
    • Occipital bone (os occipitale) – a large middle occipital hole which follows the spinal canal. On the sides of the bumps that are used for connection to the first cervical vertebra.
    • Parietal bone (os parietale) – paired bone-shaped square pan. Between the bones of the sagittal suture, seam lambdový forms a bond with the bone occipital bone seam crown to the front.
    • Frontal bone (os frontale) – forms the basis for the orbit and forms the upper floor of the nasal cavity.
  • Scum cranial (skull base) – temporal bone, wedge, ethmoid, lacrimal, nasal furrows and inferior turbinate.
    • Temporal bone (temporal bone) – contains slots for hearing and equilibrium organs. This is a pair of bone that has a complicated shape. Bonds to cheekbone, jaw and hyoid bone.
    • Bone wedge (os sphenoidal) – unpaired bone in the middle of the skull base, part of the 3 projections body extends backward in the Turkish saddle.
    • Ethmoid bone (os ethmoidal) – the sides are placed in bone cavities, which withdraws from the nasal concha.
    • Lachrymal bone (os lacrimale) – composed of small bones stake next orbit.
    • Nasal bone (os sucked) – the two bones that form the basis of the root and bridge of the nose.
    • Furrows bone (vomer) – forms the posterior part of the nasal septum.
    • Inferior turbinate (concha nasalis inferior) – thin flat bone withdrawing from the wall of the nasal cavity.

Bottom jaw

A separate Chapters forms the lower jaw is the only one is movable and is associated with a single skull and jaw joint. Basic movements are opening and closing the mouth. To a limited extent it is possible to move the lower jaw and forwards, backwards and sideways.
