An example of a seam on a nerve. The purpose of such a suture is to connect the edges as smoothly as possible with the least trauma to the nerve itself and the tissues surrounding it. For the first time such seams were performed in 1863 by Nelaton and in 1864 by Lange. P.S. I know from myself that when you see a nerve for the first time, you are surprised that it is of this size. They are really quite tangible, as the sciatic nerve of an adult is 1.1 cm in diameter (thicker than an average ballpoint pen. I just measured it)

Take a closer look and compare, on the left - a new healthy heart, on the right - an obsolete one. Pay attention to the size, wall elongation, and the amount of yellow deposits (fatty tissue) on the old heart. There may be many reasons for this, but the result is the same - stretched and thin walls are not capable of compressing and pushing blood with sufficient force.

The lower grasping reflex, I think it is not necessary to say from whom we inherited it. The reflex is triggered by pressing the pad of the toes on the baby's sole. In healthy children, it lasts up to 14 months.
