In order to understand which skin conditions are normal for a child and which are pathological, it is very important to know the basic functions and structural features of the baby's skin.
The mammary glands of newborns develop in a special way in utero and after birth, so it is very important to distinguish between the features of the physiological process and the onset of the disease.
From the sixth week of embryonic development, almost simultaneously with organs such as the heart and lungs, the mammary glands of children begin to form.
The mammary gland lies on the pectoralis major and partly on the anterior serratus muscles. Approximately in the middle of the most convex area of the chest is a colored area - the nipple field, in the middle of which the nipple of the breast rises.
The orbit of the eye is a pear-shaped cavity, the exit from which is represented by the optic nerve canal. Its intraorbital portion is longer (25 mm) than the distance from the posterior pole of the eye to the optic nerve canal (18 mm).
The normal position of the eyeballs is parallelism of the visual axes when fixating a distant object or their intersection when fixating a close object.
Binocular vision, i.e. vision with two eyes, when an object is perceived as a single image, is only possible with clear, coordinated movements of the eyeballs.
Choroid (from Latin chorioidea) is the vascular membrane itself, the posterior part of the vascular tract of the eye, located from the dentate line to the optic nerve.
