RACK 5 EMBERYLOGY WITH ANOMALIES

Gangrenous cholecystitis (GC) is defined as necrosis and perforation of the gallbladder wall as a result of ischemia following progressive vascular insufficiency.1,2 GC is a severe complication of cholelithiasis.3,4 Factors s

cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.

The thyroid gland is an endocrine gland located in the neck, just below the larynx and in front of the trachea. It consists of two lobes connected by a narrow isthmus and is surrounded by several important structures, including the trachea, esophagus, and carotid arteries.

The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans, it is in the neck and consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the thyroid.

Stages of Growth Month-by-Month in Pregnancy

What is the umbilical cord?

The umbilical cord is a tube that connects you to your baby during pregnancy. It has three blood vessels: one vein that carries food and oxygen from the placenta to your baby and two arteries that carry waste from your baby back to the placenta. A substance called Wharton’s jelly cushions and protects these blood vessels. The umbilical cord starts to form at about 4 weeks of pregnancy and usually grows to be about 22 inches long.

Placental circulation[edit]

The placenta is a temporary embryonic and later fetal organ that begins developing from the blastocyst shortly after implantation.

A full-term fetus is one that has completed the entire 40 weeks of gestation and is ready to be born. At this stage, the fetus is fully developed and typically weighs between 5.5 to 9 pounds (2.5 to 4 kg) and is around 19 to 21 inches (48 to 53 cm) in length.

The organs are fully matured, and the lungs have developed to the point where the fetus is capable of breathing on its own once it is born. The digestive system is also fully functional, and the fetus is able to digest and process breast milk or formula.

At 8-12 weeks of gestation, the fetus is approximately 1.6 to 2.4 inches (4 to 6 cm) long and weighs around 0.5 to 0.7 ounces (14 to 20 grams). The fetus has distinct human characteristics, including facial features such as a small nose, ears, and lips, and fingers and toes that are fully formed. The vital organs, such as the heart, liver, kidneys, and lungs, are also developing rapidly during this stage.
