1. Introduction. The human umbilical cord (hUC) is a conduit about 50-60 cm long and 1-2 cm in diameter, connecting the abdominal wall of the fetus to the placenta for exchange of nutrients and gasses during gestation [].The hUC consists of a vein and two arteries surrounded by an embryonic connective mucous tissue, known as Warton's jelly, that contains a very interesting population of. Slide 7-Human umbilical cord: mucous tissue (also called Wharton's jelly) Return to Epithelium and Connective Tissue Page. Return to Image Bank Home Page. Slide 7-Umbilical cord: Slide 7-Umbilical cord: Slide 7-Umbilical cord: Slide 7-Umbilical cord. The umbilical cord is the vital connection between the fetus and the placenta. Umbilical cord development begins in the embryologic period around week 3 with the formation of the connecting stalk. By week 7, the umbilical cord has fully formed, composed of the connecting stalk, vitelline duct, and umbilical vessels surrounding the amniotic membrane. The umbilical vessels carry the fetal blood. The umbilical cord contains two arteries and one vein. Slide 40 Low power view of the "fetal" surface of the placenta. The right-hand surface is the thick, pale pink chorionic plate. Extending to the left, from the plate, are some large, pale pink, chorionic stem villi which are seen giving off branches along their edges.

Histology @ Yale. Slide List. Umbilical Cord. Umbilical Cord The umbilical cord is mostly made up of connective tissue known as Wharton's Jelly and has relatively few cells. The cord has one large umbilical vein and two umbilical arteries. These vessels transport blood to and from the placenta, where exchange between the mother and fetus takes. The umbilical cord is a fetal organ connecting the placenta to the developing fetus. This structure allows for the passage of oxygen and nutrients from the maternal circulation to the fetal circulation. In doing so, it also functions to remove waste products from fetal circulation. The umbilical cord attaches to the fetus at the umbilicus and. The umbilical cord connects the fetus to the placenta, and normal function is the only mechanism for fetal oxygenation and nutrition once present.. The spirals of the cord have been studied in 5000 cords by morphometry and histology . A left twist was found in 79% with a left/right ratio of 3.7:1.0; in twins, the left direction was found in. The umbilical cord, connection between fetus and mother, is one of the most important anatomical structures related to the development of the animal during their stage of formation due to its participation as responsible of the exchange of nutrients and protection of the structural vessels.

The surface of the umbilical cord is a single layer of cuboidal to squamous amnionic epithelium. Specimen No. 32. Spleen, human, H&E. use other slides to see a more normal histology for these organs. Slide 9 notes for lymph nodes: Two lymph nodes are present on this slide. Dense connective tissue forms the capsule that surrounds the lymph. Umbilical Cord (General Embryology) 1. UMBILICAL CORDDr. Sherif Fahmy. 2. Morphology of Umbilical Cord It is the connection between placenta and fetus. • Length: 50 - 60 cm • Diameter: 2 cm. • Shape: Tortous, showing false notes. • Contents: 2 umbilical arteries, one umbilical vein embedded in wharton's jelly and surrounded by.
Describe the structural changes that occur in the uterus over the course of the menstrual cycle and pregnancy. Characterize the histological features of the oviduct, uterus, cervix, and vagina, with particular attention to the mucosal linings of these tissues. Embryonic Connective Tissue - the umbilical cord is an example of embryonic connective tissue. The umbilical cord connects the developing fetus and the placenta. The bluish-pink color is from the abundant ground substance (blue) and sparse collagen fibers (pink). The collagen and muscle of blood vessels is stained pink. (Azan can be used to.

Mucoid connective tissue is a fetal tissue present in the umbilical cord. It consists of widely separated mesenchymal cells and ground substance with an abundance of hyaluronic acid. This ground substance, also referred to as Wharthon's jelly, provides insulation and protection to the blood vessels of the umbilical cord. In placental mammals, the umbilical cord (also called the navel string, birth cord or funiculus umbilicalis) is a conduit between the developing embryo or fetus and the placenta.During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried.
