Suture is a term that derives from the Latin word suture. In the context of medicine, a suture is a sewing which is carried out with the aim of close a wound. For instance: “The suture scar will remain for life”, “After the accident, the young man received eight stitches on his left arm”, “It is a very small wound that will heal on its own, it is not necessary to perform a suture”.
The purpose of the suture is to rejoin what was separated or damaged: a tissue, an organ, a vessel, etc. When the wound does not close on its own, naturally, a doctor may develop a suture with the aim of putting what was torn back together and allowing cicatrization.
Such a suture can be compared to the action of sew a garment. The doctor sews the wound with a hypoallergenic material and ties a tie to make the suture firm. When performing a suture, apply surgical points. With the wound closed, certain substances and microorganisms are prevented from entering the body, avoiding infections.
Generally, the stitches must be removed through a new procedure. There are sutures, however, made with materials that are absorbed by the body.
It is known as suture, on the other hand, to a class of joint fibrous that takes place only in our skull, that is, in the bones of our head. Thanks to these sutures, which are joined through the so-called Sharpey fibers, the skull can enjoy a moderate amount of movement, which also contributes to its elasticity and compliance (ability to elongate or distend to withstand the environment, and then regain its original size).
Usually the skull a newborn child does not have all the necessary welds between the different bones of the head, and from this phenomenon the well-known “fontanelles” arise, which are the soft parts that doctors advise to touch with great care. This process by which the bones fuse together is called craniosynostosis
Throughout the life of an adult, the relative position of each bone in the head continues to change, at a much slower rate than it does in the first months and years of life, and this can be very useful to archaeologists and scientists. forensic doctors to determine the age of a subject. In fact, the sutures in the skull of an elderly person can become bone.
It should be noted that the only case of bones of the head that are not articulated by a suture is that of the jaw and skull (the so-called temporomandibular joint). Let’s look at some of the many skull sutures:
* coronal: separates the parietal bone from the frontal bone and consists of tissue fibrous conjunctiva. It is one of those that are not appreciated in newborns;
* lambdoid: joins the occipital bone with the parietal bones, at the back of the head, and extends at the occipitomastoid suture. Its name, as can be deduced, derives from the resemblance it bears with the letter lambda, of the Greek alphabet;
* occipitomastoid: it is located between the mastoid portion of the bone temporal, and occipital bone;
* sphenofrontal– joins the frontal bone and the sphenoid;
* flaky: articulates the temporal and parietal bone;
* temporozygomatic: it is between the temporal bone and the zygomatic bone;
* frontozygomatic: it is the suture that joins the zygomatic bone with the frontal bone and the integrity of the structure of the bones of the covering of the skull;
* sagittal: also known as interparietalas it fuses the two parietal bones.
