ecdysial suture造句

• The ecdysial suture is longitudinally placed on the vertex and separates the epicranial halves of the head to the left and right sides.
• The ecdysial suture is made of the coronal, frontal, and epicranial sutures plus the ecdysial and cleavage lines, which vary among different species of insects.
• Depending on the insect, the suture may come in different shapes : like either a Y, U, or V . Those diverging lines that make up the ecdysial suture are called the frontal or "'frontogenal "'sutures.
