yogabook / bones / cranium/skull

The skull (lat. cranium) refers to the bones of the head. It consists of 22 – 30 bones (depending on age, some grow together) and is divided into the part that surrounds the brain (neurocranium) and the facial skull (viscerocranium).
The neurocranium consists mainly of the following bones:

  • one occipital bone(Os occipitale)
  • Parietal bone (Os parietale, left and right)
  • Temporal bone (Os temporale, left and right)
  • Sphenoid bone (Os sphenoidale)
  • Parts of the frontal bone (Os frontale)
  • Ethmoid bone (Os ethmoidale)

The viscerocranium consists of:

  • Dividing the frontal bone
  • Zygomatic bone (Os zygomaticum, left and right)
  • Upper jaw (maxilla), seen exactly in pairs
  • Intermaxillary bone (Os incisivum, left and right, fuses with the upper jaw before birth)
  • Lower jaw (mandible)
  • Nasal bone (Os nasale, left and right)
  • Inferior turbinate bone (Os conchale inferius, left and right)
  • Lacrimal bone (Os lacrimale, left and right)
  • Palatine bone (Os palatinum, left and right)
  • Plowshare leg (the vomer)

The skull is held and moved by many muscles,
but also carries many muscles, such as the muscles of mastication or those used for facial expressions
