Key ideas in Bones of the Head and Neck

  • The roof of the skull consists of multiple curved plates joined along wavy lines called sutures
  • Wavy suture lines distribute and dissipate blunt mechanical forces across adjacent bones rather than concentrating stress at an impact site
  • Infant skull plates are separated by flexible fibrous gaps so the head can compress during birth and expand rapidly as the brain grows
  • Through childhood and early adulthood, these gaps tighten into interlocking fibrous joints
  • In later adulthood, the seams gradually ossify and merge into solid bone
  • The external occipital protuberance is a prominent bony landmark at the lower midline back of the head
  • It provides a sturdy anchoring point for the nuchal ligament and neck muscles that counteract gravity to keep the heavy head balanced upright
  • The temporal bone houses the delicate fluid-filled organs of hearing (cochlea) and equilibrium (semicircular canals)
  • The petrous part of the temporal bone is exceptionally dense and rock-like specifically to shield these fragile sensory organs from trauma and distortion
  • The pterion is an H-shaped junction on the temple where four cranial bones meet
  • It is the thinnest, most fragile structural point on the cranial vault
  • The middle meningeal artery runs directly along the inner surface of the pterion, making it prone to rupturing and causing life-threatening bleeding during a side impact
  • The upper jaw (maxilla) is fused to the surrounding facial bones and skull frame rather than moving on its own
  • Dense vertical struts of bone in the maxilla transfer biting forces up into the forehead and orbit rims to dissipate stress
  • The cheekbone forms an arch (the zygomatic arch) built from parts of two different bones joining together
  • It acts like an open bridge, leaving a tunnel underneath so powerful chewing muscles can pass through and move freely
