The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. Abdominal Region: Prefix / Suffix / Derivation: Definition: Organs Involved: RIGHT HYPOCHONDRIAC REGION: Hypo – below. Which organ(s) are located in the Left Iliac Region? It inserts into the linea alba behind the rectus abdominis. However, the term is in common usage. The left lower quadrant (LLQ) of the human abdomen is the area left of the midline and below the umbilicus. Important organs here are: The left upper quadrant (LUQ) extends from the median plane to the left of the patient, and from the umbilical plane to the left ribcage. Abdominal organs can be highly specialized in some animals. The external obliques are more superficial and they are also involved in rotation and lateral flexion of the spine.

It originates from Poupart's ligament, the inner lip of the ilium, the lumbar fascia and the inner surface of the cartilages of the six lower ribs.

There are also specific routines which target each of these muscles. When strengthened, the abdominal muscles provide flexibility as well. [3][4], ("Hypo-" means below; "epi-" means above; "chondron" means cartilage (in this case, the cartilage of the rib) and "gaster" means stomach. These terms are not used in comparative anatomy, since most other animals do not stand erect. It is attached to the thoracic cavity by the diaphragm. It contains vital organs involved in digestion, such as the intestines and the liver. star. There are three layers of muscles in the abdominal wall. [6], The transverse abdominis muscle is the deepest muscle, therefore, it cannot be touched from the outside. The regions occupied by stomach are epigastric, umbilical and hypochondriac regions. The three main centrally positioned regions are the epigastric region, the umbilical region, and the hypogastric region also known as the pubic region. It is a simple sugar which is manufactu... Q: what is the pathophysiology related to CVA due to thrombus vs. embolus. The equivalent term for animals is left anterior quadrant. 1 Rating. The abdomen is sometimes highly modified. It can greatly affect the body's posture. The lower right portion of the abdomen contains a part of the colon, and the right ovary in women. They originate at the pubis bone, run up the abdomen on either side of the linea alba, and insert into the cartilages of the fifth, sixth, and seventh ribs. Side-by-side comparison of the quadrants and regions of the, https://en.wikipedia.org/w/index.php?title=Quadrants_and_regions_of_abdomen&oldid=941423320, Articles which use infobox templates with no data rows, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 February 2020, at 14:33. This in other animals is the right posterior quadrant. [10] In a newborn, it may represent a diaphragmatic hernia. [9], A scaphoid abdomen is when the abdomen is sucked inwards. There is an associated risk of severe blood loss and infection. Depending on the type of society, excess weight can be perceived as an indicator of wealth and prestige due to excess food, or as a sign of poor health due to lack of exercise. Lower ribs can also enclose ventral and lateral walls. In many cultures, bare abdomens are distinctly sexualized and perceived similarly to breast cleavage. The right subcostal margin corresponds to the lower limit of the liver, while the right nipple is about half an inch above its upper limit. Functionally, the human abdomen is where most of the digestive tract is placed and so most of the absorption and digestion of food occurs here. Best Pract Res Clin Gastroenterol. If your blood sugar level is low fromskipping lunch, what reaction (discussed in this exercise) wi... A: Glucose ( C6H12O6) present in blood is known as blood sugar. Questions are typically answered within 1 hour.*. Stomach is a muscular bag forming the most distensible part of the Human Digestive System. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax.[2][3]. The upper lateral limit of the abdomen is the subcostal margin (at or near the subcostal plane) formed by the cartilages of the false ribs (8, 9, 10) joining one another. The main work of the abdominal muscles is to bend the spine forward when contracting concentrically.[7]. The abdominal cavity contains most organs of the digestive system, including the stomach, the small intestine, and the colon with its attached appendix. The abdomen can also be divided into nine regions. These lower limits are marked by visible grooves. The 2 bottom sections are just above the pubic bone and usually not visible, hence, the 6 pack abs.

Most of the anatomical structures that will produce pain and tenderness in this region are not in fact in the concavity of the ileum. Abdominal trauma is an injury to the abdomen and can involve damage to the abdominal organs. It lies between the internal oblique and the underlying transverse fascia. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. Acute Right Iliac Fossa/Pelvic Pain; Diagnostic Imaging Pathways, Government of Western Australia, Department of Health. Both of them are involved in rotation and lateral flexion of the spine and are used to bend and support the spine from the front. Right iliac fossa : Appendix. Important organs here are: Nine regions of the abdomen can be marked using two horizontal and two vertical dividing lines. In the Collembola (Springtails) the abdomen has only six segments. There are three organs found in the right lumbar region of the human body. [11] In general, it is indicative of malnutrition.[12]. Where combined pancreas and kidney transplantation is performed via a vertical midline transperitoneal approach, the pancreas is usually placed in the right iliac fossa and the kidney in the left iliac fossa. Small Intestine and Urinary Bladder. These terms stem from "hypo" meaning "below" and "epi" means "above", while "chondron" means "cartilage" (in this case, the cartilage of the rib) and "gaster" means stomach. Gastric – stomach, belly: Below the stomach – Bladder – parts of the Sigmoid Colon – Small Intestines – Portions of the Reproductive Organ: LEFT ILIAC REGION: Left iliac crest on hip bone

If abdominal pain or signs of peritonitis are localised in the LLQ, colitis, diverticulitis, ureteral colic or pain due to ovarian cysts or pelvic inflammatory disease may be suspected. It originates at the pubic bone and is inserted into the linea alba halfway up to the navel. [citation needed] Quadrants are also often used in describing the site of an abdominal pain.[13].

The abdomen contains the insect's digestive tract and reproductive organs, it consists of eleven segments in most orders of insects though the eleventh segment is absent in the adult of most higher orders. In the region of the groin, the inguinal canal, is a passage through the layers. This is also where weakness can form, and cause inguinal hernias.[6]. The internal obliques are also deep and also affect body posture. Furthermore, together with the back muscles they provide postural support and are important in defining the form. Although, it should really be a 10 pack as there are 5 vertical sections on each side. Other digestive organs are known as the accessory digestive organs and include the liver, its attached gallbladder, and the pancreas, and these communicate with the rest of the system via various ducts. The right upper quadrant extends from umbilical plane to the right ribcage. RIGHT ILIAC REGION: RIGHT ILIAC REGION: LEFT ILIAC REGION: Table 2: Summary of Definitions, Derivation and Organs involved in the Nine Abdominal Regions. It is the combination of the linea alba and the tendinous intersections which form the abdominal "six-pack" sought after by many people.

The abdominal wall is split into the posterior (back), lateral (sides), and anterior (front) walls.

In Apocrita (bees, ants and wasps), the first segment of the abdomen is fused to the thorax and is called the propodeum. The division into four quadrants allows the localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved.

The equivalent term for animals is right anterior quadrant. Strength is gained by the criss-crossing of fibers, such that the external oblique runs downward and forward, the internal oblique upward and forward, and the transverse abdominal horizontally forward.[6].
