[Functional morphology of the neonatal umbilical cord during cesarean section]

The morphology of the neonatal umbilical cord was studied in 23 women during elective surgical delivery and in 32 women during normal physiological delivery. Organ- and histometric indices were used. These included: length, weight, a linear weight unit; the average diameter of the umbilical cord, etc. The significant increase of organometric indices (a linear weight unit of weight, the average diameter of the umbilical cord) and histometric ones (a drastic venous lumen increase, a significant increase in the proportion of Wharton's jelly) document acute umbilical blood flow disorder in the absence of the conditions characteristic for normal delivery. Moderately pronounced edema of the umbilical cord peripheral layer emerges. A complex of morphofunctional umbilical cord changes during surgical delivery serves as predictor of neonatal respiratory distress syndrome.

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Embryonic Connective Tissues01:20

Embryonic Connective Tissues

During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development. Mesenchyme is...
Uterus and Cervix01:18

Uterus and Cervix

The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...
Histology of the Uterus01:19

Histology of the Uterus

The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.
The endometrium is the...
