Ossification of Sphenoid - Intrinsic Ligaments of The Sphenoid

Intrinsic Ligaments of The Sphenoid

The more important of these are:

  • the pterygospinous, stretching between the spina angularis and the lateral pterygoid plate (see cervical fascia);
  • the interclinoid, a fibrous process joining the anterior to the posterior clinoid process;
  • and the caroticoclinoid, connecting the anterior to the middle clinoid process.

These ligaments occasionally ossify.

Famous quotes containing the word intrinsic:

    The truth is that literature, particularly fiction, is not the pure medium we sometimes assume it to be. Response to it is affected by things other than its own intrinsic quality; by a curiosity or lack of it about the people it deals with, their outlook, their way of life.
    Vance Palmer (1885–1959)
