Surface marking of Liver
The median nerve lies first lateral then medial to the brachial artery, crossing it at the mid-upper arm, usually superficially but occasionally deeply. Bregma: It corresponds to the middle point of a line joining the external acoustic meatuses of the two sides across the vertex. These numbers are for an adult spine. When a symptomatic gallstone occurs, it is often managed by waiting for it to be passed naturally. Because of its strategic location and multidimensional functions, the liver is also prone to many diseases. From below, the two additional lobes are located between the right and left lobes, one in front of the other.
The deep epigastric artery, The Gall-Bladder Fig. Muscles and tendons The anterior fold of the axilla is formed by the pectoralis major, and its posterior fold by the teres major and latissimus dorsi. The horizontal part runs with a slight upward slope from the end of the descending part to the left of the middle line; the ascending part is vertical, and reaches the transpyloric line, where it ends in the duodenojejunal flexure, about 2. The bare area of the liver is a site that is vulnerable to the passing of infection from the abdominal cavity to the. The subcutaneous inguinal ring is situated 1 cm. Join these points by a straight line which lies above and behind the tortuous facial artery.
This oxygen needs to get into the blood, so that the cardiovascular system can fulfil its role of transporting the oxygen to the working cells. This sometimes results in , when the metabolite is more toxic than its precursor. Plane midway between transpyloric and transtubercular planes. Aberrant splenic tissue may occur, especially at the splenic hilum. And then you've got the coronary ligaments which come down from the diaphragm. The middle region of the lower zone is the hypogastric or pubic, and the lateral are the right and left iliac or inguinal.
This corresponds to the level of the bifurcation of the aorta. Arch of cricoid cartilage, at the level of C 6 vertebra: d. A point at the infra-orbital foramen which lies vertically below the supra-orbital notch and 1 cm below the infra-orbital margin. This constitutes one cycle of breathing. To indicate the greater curvature a curved line is drawn from the cardiac orifice to the summit of the fundus, thence downward and to the left, finally turning medialward to the pyloric orifice, but passing, on its way, through the intersection of the left lateral with the transpyloric line. Lobules are the functional units of the liver.

This plane passes through the pylorus, the pancreatic neck, the duodenojejunal flexure, the fundus of the gall-bladder, the tip of the 9th costal cartilage felt as a distinct 'step' , and the hila of the kidneys. Inflammation can also be caused by other viruses in the family such as the. Plane through joint between body and xiphoid process of sternum. Medial to the renal impression is a third and slightly marked impression, lying between it and the neck of the gall bladder. The triangular area formed by joining these points represents supra-clavicular part of the plexus. The left lobe extends to the left of the sternum about 5cm. Approximately, human breath 24480 times in a day.
A point on the vertex midway between the nasion and inion. The muscular layer is surrounded by a layer of connective and tissue. The lower pole is situated midway between the transpyloric and intertubercular planes, 7 cm. It is located close to the right of the , between the bare area and the caudate lobe, and immediately above the renal impression. Posterior to the greater is the duodenum.

The divides the liver into a left and right lobe. Mastoid process: It is overlapped by the lobule of the ear. The descending colon courses down through the left lumbar region, lateral to the left lateral line, as far as the iliac crest see footnote p. Nonparenchymal cells constitute 40% of the total number of liver cells but only 6. At the end of each tiny branch, or bronchiole, is a structure called alveoli. The liver performs several roles in : The liver synthesizes and stores around 100 g of via , the formation of glycogen from glucose.
The liver bud separates into the lobes. The origins of the liver lie in both the ventral portion of the endoderm being one of the three embryonic and the constituents of the adjacent. Organs in volvus are at risk of infarct - surgical emergency a specialization of the peritoneum; a few layers of fat - fat apron; rather highly vascularized; aka the policeman of the abdomen. Alveoli found inside the lungs which take oxygen and allow it to seep into the capillaries and carbon dioxide is exchange. This extends into the structure of the liver, by accompanying the veins and arteries , ducts, and nerves at the hepatic hilum. Oxygen is provided from both sources; about half of the liver's oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries.
