The stomach is a muscular organ located in the upper abdomen, just below the diaphragm. It is part of the digestive system and plays a crucial role in breaking down food into nutrients that can be absorbed by the body.

The umbilical cord is a flexible cord-like structure that connects the fetus to the placenta in the uterus during pregnancy. Here are some key points about the anatomy of the umbilical cord:

The umbilical cord is approximately 50-60 cm in length and 2 cm in diameter.

It consists of two arteries and one vein encased in a gelatinous substance called Wharton's jelly.

The two arteries carry deoxygenated blood and waste products from the fetus to the placenta, while the vein carries oxygenated blood and nutrients from the placenta to the fetus.

Anatomical Relations

The kidneys sit in close proximity to many other abdominal structures which are important to be aware of clinically:

The placenta is an organ that develops during pregnancy to provide oxygen and nutrients to the developing fetus and remove waste products. Here are some anatomical points and clinical aspects of the placenta:

Anatomical points:

The muscles acting on the foot can be divided into two distinct groups; extrinsic and intrinsic muscles.

Sacrococcygeal teratoma is a type of tumor that develops at the base of the spine, in the sacrococcygeal area. It is the most common tumor found in newborns, with a reported incidence of approximately 1 in 35,000 to 40,000 live births.

Sacrococcygeal teratomas are thought to arise from germ cells, which are cells that give rise to eggs or sperm. These tumors can contain a variety of different tissues, including hair, teeth, bone, cartilage, muscle, and nerve tissue. The tumors can vary in size and can be either benign or malignant.

Clinical Relevance: Disorders of the Stomach

Gastro-Oesophageal Reflux Disease

 This is a digestive disorder affecting the lower oesophageal sphincter. It refers to the movement of gastric acid and food into the oesophagus.

GORD is a common condition, affecting 5-7% of the population. Symptoms include dyspepsia, dysphagia, and an unpleasant sour taste in the mouth.

There are three main causes of reflux disease:

The spleen is an important organ of the lymphatic system that is located in the upper left quadrant of the abdomen, beneath the diaphragm and behind the stomach. It is a soft, purplish-red organ that is roughly the size of a fist and weighs between 150 and 200 grams.
