Precordial Region

The precordial region of the chest is the area of ​​the anterior wall of the sternum, limited by the lower contour of the heart and the following landmarks:

- proximally - by the crest of the manubrium of the sternum and the medial-lower edge of the cartilage of the 5th rib; - distally - the upper thoracic nipple and the IV rib; - laterally - by the lateral borders of the posterior sections of the mammary glands and relatively symmetrical accumulations of fatty tissue; - medially - the lower borders of the lower branches of the cartilages of the VI - IX ribs, the cartilage of the X rib becomes medially impalpable from late gestation.

Determination of the surface structure of the anterior chest wall is possible already in the early stages of pregnancy due to the transformation of fiber and muscles during their compaction. Starting from the seventh week of gestation, the formation of a fetal bladder occurs, which is formed due to the movement between the amniotic vessels of the egg released during the process of fertilization and the amnion mucous membrane exfoliating above it. An increase in pressure in the cavity of the amniotic sac leads to expansion of the intervillous spaces of the placental lobes and tension of the decidua, which normally grows gradually. Due to this, the placenta separates, its volume increases and transforms until the formation of a dense ball

Introduction

The precordial zone is an area located on the anterior wall of the chest and limited by the projection of the edges of the heart. This area is important for understanding the functions of the cardiovascular system and may be associated with various diseases and pathologies. In this article we will look at the functions of the precordial zone, its anatomy, possible diseases associated with this
