Anatomical terms of bone |
The lesser wings of the sphenoid or orbito-sphenoids are two thin triangular plates, which arise from the upper and anterior parts of the body, and, projecting lateralward, end in sharp points [Fig. 1].
In some animals, they remain as separate bones called orbitosphenoids.
