What is the front Shar?

The frontal stitch is a place where in early childhood the bilateral half of the front bone in the skull meets to form a vertical line in the middle of the forehead. In the end, they connect and form one front bone, usually between six and eight years. The existence of the frontal stitch allows the skull to compress to allow the baby's head to fit into the birth canal during delivery. As the brain completes growth and in the first few years of the child develops bones of the skull, the gaps between them are close. Skull skull skull The skull is formed by the occipital bone in the lower back, the paired parietal bones covering the upper part of the skull, the temporary bone on both sides and the front bones including the upper front. Bounded by the above -mentioned parietal bones, sphenoid bones of temples laterally and tdne nasal bones and eye sockets below, the frontal bone is bounded by 12 other bones. It is rounded above and on both sides and irregular below where it forms the upper edge of each eye socket.

In an adult skull, what seems to be jagged with cracks can see how it runs in the middle of the frontal bone between the arc or eyebrows to the hair line. This is the fused rest of the frontal stitch. During the development of the fetus, the frontal bone actually begins like one bone, the front stitch develops before giving birth. At the time the child is born, the stitch is visible as a narrow gap full of small tissue fibers. Known as Sharpey fibers are composed mainly of collagen and holds two halves of the frontal bone together and at the same time lend an elastic property, allowing bones to move together and apart.

as a child of grows, bones begin to move permanently, a process known as ossification. Some individuals will never happen; The remaining frontal stitch then becomes known as the metopic sharia. This does not necessarily be considered significant or dangerous, but the same cannot be said about the opposite state. In some cases, the fuse of the frontThe bones and the frontal stitch disappear too early before the brain ends in growth in the skull. This prevents further expansion of the skull and exerts pressure on the brain, which is known as trigonocephalies, although the premature fusion of the frontal bone can also develop as a result of a brain that is not fully developing in the skull.
