A syndesmosis (Germanized from syndesmosis , from the Greek syn “together” and desmos “band”) or band-like is a form of a fake joint . In the case of tape, two bones are held together by connective tissue . It belongs to the connective tissue bone connections ( Articulationes fibrosae ). In contrast to the other connective tissue bone connections ( sutura , gomphosis ), the connective tissue is flat, so it forms a more or less wide membrane. An amphiarthrosis , in contrast to the syndesmosis, is a real joint (a diarthrosis ), but it is extremely tight, so that it allows little or no movement.
Connective tissue bone connections occur on the forearm , thigh and ankle . The radius and ulna are connected by a membrana interossea antebrachii , the tibia and fibula by a membrana interossea cruris . A tibiofibular syndesmosis , which is composed of the tibiofibular ligaments , occurs in the ankle (see also the upper ankle ). In addition, many mammals also have real joints at the ends of the two respective bones .
The tape joints also include:
- Ligaments between the vertebral arches (e.g. ligamenta flava )
- Ligamentum stylohyoid as a suspension of the hyoid bone ( os hyoideum ) on the stylus process ( processus styloideus ) of the temporal bone .
