Splanchnology is the study of the viscera. [8] The term "visceral" is contrasted with the term "parietal", meaning "of or relating to the wall of a body part, organ or cavity". [9] The two terms are often used in describing a membrane or piece of connective tissue, referring to the opposing sides. [10]
The viscera are also covered by visceral peritoneum. Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space. [1] It contains a serous fluid called peritoneal fluid that allows motion. This motion is apparent of the gastrointestinal tract. The peritoneum, by virtue of its connection to the two (parietal ...
Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Visceral structures are highly sensitive to distension (stretch), ischemia and inflammation, but relatively insensitive to other stimuli that normally evoke pain such as cutting or burning.
The term derives from the Neo-Latin splanchno-, from the Greek σπλάγχνα, meaning "viscera". More broadly, splanchnology includes all the components of the Neuro-Endo-Immune (NEI) Supersystem. [5] [6] An organ (or viscus) is a collection of tissues joined in a structural unit to serve a common function. In anatomy, a viscus is an ...
Serous membranes have two layers. The parietal layers of the membranes line the walls of the body cavity (pariet- refers to a cavity wall). The visceral layer of the membrane covers the organs (the viscera). Between the parietal and visceral layers is a very thin, fluid-filled serous space, or cavity. [4]
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...
The course of GVA fibers from organs in the pelvis, in general, depends on the organ's position relative to the pelvic pain line.An organ, or part of an organ, in the pelvis is said to be "above the pelvic pain line" if it is in contact with the peritoneum, except in the case of the large intestine, where the pelvic pain line is said to be located in the middle of the sigmoid colon. [6]
Visceroptosis is a prolapse or a sinking of the abdominal viscera (internal organs) below their natural position. "Ptosis" being the defining term, any or all of the organs may be displaced downward. When only the intestines are involved, the condition is known as enteroptosis.
