Suture
in ordinary language, the act of sewing; the line along which two things are joined, united, or sewed together, so as to form a seam, or something resembling a seam. Technically, in anatomy, the immovable junction of two parts by their margins; as, the sutures of the skull, i. e., the lines of junction of the bones of which the skull is composed.
Various types of suture exist, as the serrated or dentated suture, the squamous or scaly suture, and the harmonic suture or harmonia. Arranged according to their situation, there are coronal, frontal, fronto-parietal, occipito-parietal, and many other sutures. In botany, the line formed by the cohesion of two parts. If the suture formed by the carpellary leaves in a pistil face the center of a it face the perianth, the dorsal suture.
The former corresponds to the margin, and the latter to the midrib of the carpellary leaf. In entomology, the line formed by the meeting of the elytra of a beetle when they are confluent. In surgery, the uniting of the lips or edges of a wound by stitching. In zoölogy, the outlines of the septa in the Tetrabranchiata, from their resemblance to the sutures of the skull. When these outlines are folded, the elevations are called saddles, and the intervening depressions lobes.
