Articulations of Skull

Most of the bones of the skull are united by sutures. A few are united by cartilage (synchondrosis) and one (temporomandibular) joint is a synovial joint

  • The sutures have been named according to the bones involved in their formation. E.g. interparietal suture, interfrontal suture, frontoparietal suture, temporoparietal suture etc.
  • The principal synchondroses are between (1) basioccipital and post sphenoid (2) post sphenoid and presphenoid (3) parts of occipital. Most of these joints ossify in life.
  • symphysis occurs between the two halves of the ventral ends of the mandible at the median plane. This symphysis does not ossify even in adult life.
