Formation of larynx topographic-anatomic relations with neck organs and structures in the intermediate fetal period of ontogenesis

Abstract

Objectivesto present topographic and anatomic characteristics of the larynx relationship with neck organs and structures in the intermediate fetal period of human ontogenesis. Material and methods.The study included 85 organocomplexes of the fetuses neck of both sexes, from the 14th to the 27th week of development. The study material was divided into 2 age periods: the first group fetuses aged 1420 weeks; the second group 2127 weeks. The classical morphological techniques were used: (macromicroscopic preparation, modified method of saw cuts according to N.I. Pirogov, histotopographic method). Results.Larynx syntopy with thyroid gland, cervical esophagus, thymus, submandibular glands was described in detail. Larynx skeletotopy with incisurae jugularis sterni, cervical vertebrae, hyoid bone, mandible was described quantitatively. Conclusion.The data, obtained as a result of the study, supplement the data on the topographic anatomy of larynx and some neck organs and structures in the prenatal period of human ontogenesis. The revealed formation features of larynx and other neck organs and structures topography can be used in the study of intravital anatomy.
