Synchondrosis

from Wikipedia, the free encyclopedia

A synchondrosis (Germanized from Synchondrosis , from Greek syn "together" and chondros "cartilage") or cartilaginous is a connection between two bones through hyaline cartilage . This connection belongs to the cartilaginous bone connections ( Articulationes cartilagineae ) and thus to the so-called false joints and is relatively little mobile. A connection through fiber cartilage is called symphysis .

Synchondroses occur in the mammalian body :

  • between the skull bones of the skull base ( Synchondroses cranii )
  • between the two halves of the lower jaw ( intermandibular synchondrosis )
  • between the individual pieces of bone of the sternum ( synchondroses sternales )
  • between the bony parts of the ribs and the sternum (costal cartilage, cartilago costalis )

The growth plate between the epiphysis and diaphysis in growing long bones also corresponds morphologically to a specialized synchondrosis. Synchondroses can ossify in old age ( synostosis ).
