MAOI therapy is associated with many adverse drug reactions, and patients are at risk of hypertensive emergency triggered by foods with high tyramine content, and certain drugs.

The liver is made of very soft, pinkish-brown tissues encapsulated by a connective tissue capsule. This capsule is further covered and reinforced by the peritoneum of the abdominal cavity, which protects the liver and holds it in place within the abdomen.

The peritoneum connects the liver in 4 locations: These connections are not true ligaments in the anatomical sense; rather, they are condensed regions of peritoneal membrane that support the liver.

Knowledge Base

The wide coronary ligament connects the central superior portion of the liver to the diaphragm. The falciform ligament runs inferiorly from the diaphragm across the anterior edge of the liver to its inferior border. At the inferior end of the liver, the falciform ligament forms the round ligament ligamentum teres of the liver and connects the liver to the umbilicus.

The round ligament is a remnant of the umbilical vein that carries blood into the body during fetal development. The liver consists of 4 distinct lobes — the left, right, caudate, and quadrate lobes. The left and right lobes are the largest lobes and are separated by the falciform ligament.

The right lobe is about 5 to 6 times larger than the tapered left lobe. The small caudate lobe extends from the posterior side of the right lobe and wraps around the inferior vena cava.

The small quadrate lobe is inferior to the caudate lobe and extends from the posterior side of the right lobe and wraps around the gallbladder.

Bile Ducts The tubes that carry bile through the liver and gallbladder are known as bile ducts and form a branched structure known as the biliary tree.

Bile produced by liver cells drains into microscopic canals known as bile canaliculi. The countless bile canaliculi join together into many larger bile ducts found throughout the liver.

These bile ducts next join to form the larger left and right hepatic ductswhich carry bile from the left and right lobes of the liver. Those two hepatic ducts join to form the common hepatic duct that drains all bile away from the liver.

The common hepatic duct finally joins with the cystic duct from the gallbladder to form the common bile ductcarrying bile to the duodenum of the small intestine. Most of the bile produced by the liver is pushed back up the cystic duct by peristalsis to arrive in the gallbladder for storage, until it is needed for digestion.

Blood Vessels The blood supply of the liver is unique among all organs of the body due to the hepatic portal vein system. Blood traveling to the spleenstomachpancreasgallbladder, and intestines passes through capillaries in these organs and is collected into the hepatic portal vein.

The hepatic portal vein then delivers this blood to the tissues of the liver where the contents of the blood are divided up into smaller vessels and processed before being passed on to the rest of the body.

Blood leaving the tissues of the liver collects into the hepatic veins that lead to the vena cava and return to the heart. The liver also has its own system of arteries and arterioles that provide oxygenated blood to its tissues just like any other organ.

Lobules The internal structure of the liver is made of aroundsmall hexagonal functional units known as lobules. Each lobule consists of a central vein surrounded by 6 hepatic portal veins and 6 hepatic arteries. These blood vessels are connected by many capillary-like tubes called sinusoidswhich extend from the portal veins and arteries to meet the central vein like spokes on a wheel.

Each sinusoid passes through liver tissue containing 2 main cell types: Kupffer cells and hepatocytes.Continued From Above Anatomy of the Stomach Gross Anatomy.

The stomach is a rounded, hollow organ located just inferior to the diaphragm in the left part of the abdominal cavity. embryologically, the brain arises from the rostral end of a tubelike structure that quickly becomes divided into three major regions.

group of structures that develop from the embryonic brain are listed below. Gross Anatomy Course Description Gross Anatomy is taught at UAMS using a combination of traditional and modern methods. Cadaver dissection is the primary teaching method and is the focal point of all teaching activities.

Clinical boxes embedded within the text helps the anatomy feel relevant – I learn best by being able to visualise how the knowledge would be of use so these references to clinical content really helped me to learn the anatomy itself. The first step to learning about an injury is understanding its underlying anatomy—in other words, you need to know how the body works, before learning how it hurts.

To that extent, this article intro.
