Rationale: The kidneys lie in the retroperitoneal space—the space behind the abdominal cavity. The spleen, liver, and stomach are all located within the anterior (true) abdomen.
What is an organ that is part of the retroperitoneal space EMT?

- Functional Pain: Pain without obvious origin, but can cause pain.
What is a peritoneal?
Summary. Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.What is localized pain?
Localized pain exists in one part of your body, and a localized infection is also restricted to one area — it hasn’t spread to other places in the body. Another way something can be localized is simply to be local, like a localized radio station or a localized source of food for school lunches.
Why is visceral pain referred?
The phenomenon of referred pain is secondary to the convergence of visceral afferent (sensory) nerve fibers entering the spinal cord at the same level as the superficial, somatic structures experiencing the pain. This leads to a misinterpretation of incoming signals by higher brain centers.
Is referred pain somatic or visceral?
Pain can be referred by deep somatic or by visceral structures. Myofascial pain syndrome is a typical syndrome characterized by referred pain from deep somatic structures. Referred pain from visceral organs is the most important from a clinical point of view.
Which of the following organs is described as retroperitoneal quizlet?
The adrenal glands, kidneys, urinary bladder and pancreas are all retroperitoneal organs.What membrane is the peritoneum?
The peritoneum is the serous membrane that lines the abdominal cavity. It is composed of mesothelial cells that are supported by a thin layer of fibrous tissue and is embryologically derived from the mesoderm.
What does it mean to be retroperitoneal?(REH-troh-PAYR-ih-toh-NEE-ul) Having to do with the area outside or behind the peritoneum (the tissue that lines the abdominal wall and covers most of the organs in the abdomen).
Article first time published onWhat is the difference between peritoneal and retroperitoneal?
Intraperitoneal space refers to the space within the peritoneum, which is a thin transparent membrane, lining the abdominal cavity, while retroperitoneal space refers to the space occurring outside the peritoneum. Thus, this is the main difference between intraperitoneal and retroperitoneal space.
Where is epigastric pain located?
Epigastric pain is pain that is localized to the region of the upper abdomen immediately below the ribs. Often, those who experience this type of pain feel it during or right after eating or if they lie down too soon after eating. It is a common symptom of gastroesophageal reflux disease (GERD) or heartburn.
Is an inflammation of the peritoneum?
Peritonitis is a redness and swelling (inflammation) of the lining of your belly or abdomen. This lining is called the peritoneum. It is often caused by an infection from a hole in the bowel or a burst appendix. You must seek medical care right away.
Is peritoneum the same as peritoneal?
The peritoneum is thin membrane that lines the abdominal and pelvic cavities, and covers most abdominal viscera. … Parietal peritoneum is that portion that lines the abdominal and pelvic cavities. Those cavities are also known as the peritoneal cavity.
What causes thickening of the peritoneum?
Peritoneal Thickening/Masses from Miscellaneous Tumors and Tumorlike Lesions. Miscellaneous etiologies such as endometriosis, splenosis, gliomatosis peritonei, and osseous metaplasia can also cause peritoneal masses and thickening.
What is disorders of peritoneum?
Peritonitis is inflammation of the peritoneum — a silk-like membrane that lines your inner abdominal wall and covers the organs within your abdomen — that is usually due to a bacterial or fungal infection. There are two types of peritonitis: Spontaneous bacterial peritonitis.
What is a referred pain?
Referred pain, as defined by Anderson, is “pain felt at a site different from the injured or diseased organ or body part.”1 Radiating pain, however, is not defined by Anderson; radiating pain is more commonly used in connection with pain perceived in somatic nerve and spinal nerve root distributions (i.e. the …

- Acute pain.
- Chronic pain.
- Neuropathic pain.
- Nociceptive pain.
- Radicular pain.
What are the three types of nociceptive pain?
- Radicular pain. Radicular pain occurs when the nerve roots are irritated. …
- Somatic pain. Somatic pain happens when any of the pain receptors in your tissues, such as muscles, bone, or skin, are activated. …
- Visceral pain.
What is the difference between visceral and referred pain?
Visceral Pain — Unlike referred pain, visceral pain comes directly from the organ involved. Because most of the organs in the abdomen don’t have many nerve fibers, the pain may be dull, hard to locate precisely, and may be either constant or intermittent.
What is somatic referred pain?
Somatic referred pain typically occurs when the source of pain lies in a deep musculoskeletal structure, from which the brain is unaccustomed to receiving nociceptive input.
What is visceral pain?
Visceral pain is pain related to the internal organs in the midline of the body. Unlike somatic pain — pain that occurs in tissues such as the muscles, skin, or joints — visceral pain is often vague, happens every so often, and feels like a deep ache or pressure.
Is referred pain sympathetic or parasympathetic?
Although it is well known that sympathetic referred pains of viscera appear on the body trunk, the fact that parasympathetic referred pains exist and are expressed on the head, sacrum and posterior thigh is not appreciated properly.
Is visceral pain sympathetic or parasympathetic?
It is somewhat unlike other pain syndromes in a sense that visceral pain activates the autonomic nervous system, specifically the parasympathetic nervous system or the sympathetic nervous system or both, which is why a lot of patients who have visceral pain also have associated nausea, vomiting and sweating.
What is meant by neuropathic pain?
Neuropathic pain is often described as a shooting or burning pain. It can go away on its own but is often chronic. Sometimes it is unrelenting and severe, and sometimes it comes and goes. It often is the result of nerve damage or a malfunctioning nervous system.
What is the difference between referred and radiating pain?
With radiating pain, the pain travels from one part of the body to another. The pain literally moves through the body. With referred pain, the source of pain doesn’t move or get larger. The pain is simply felt in areas other than the source.
What is referred pain in physiology?
Referred pain is pain perceived at a location other than the site of the painful stimulus/ origin. It is the result of a network of interconnecting sensory nerves, that supplies many different tissues.
What is shifting pain?
Migratory arthritis occurs when pain spreads from one joint to another. In this type of arthritis, the first joint may start to feel better before pain starts in a different joint. Although migratory arthritis can affect people who have other forms of arthritis, it can also result from a serious illness.
What is the difference between peritoneum and perineum?
As nouns the difference between peritoneum and perineum is that peritoneum is (anatomy) in mammals, the serous membrane lining the cavity of the abdomen and that is folded over the viscera while perineum is perineum.
Is omentum and peritoneal the same?
Summary – Peritoneum vs Omentum The peritoneum is a serous membrane that lines the abdomino-pelvic cavity and supports and protects abdominal organs. Omentum, on the other hand, is a fold of the peritoneum. Omenta form connections between the stomach and the duodenum.
What does sad pucker stand for?
One easy way to remember which abdominopelvic organs are retroperitoneal is to use a mnemonic such as SAD PUCKER: S = Suprarenal (adrenal) glands. A = Aorta/Inferior Vena Cava. D = Duodenum (second and third segments) P = Pancreas.
