A good example of visceral pain that is common place and embodies the wide spectrum of clinical presentations discussed above is a myocardial infarction (MI), more commonly known as a heart attack. This pain is secondary to ischemia of the cardiac tissue.
In the study of anatomy, viscera (sg.: viscus) refers to the internal organs of the abdominal, thoracic, and pelvic cavities. [5] The abdominal organs may be classified as solid organs or hollow organs .
In the abdomen, general visceral afferent fibers usually accompany sympathetic efferent fibers. This means that a signal traveling in an afferent fiber will begin at sensory receptors in the afferent fiber's target organ, travel up to the ganglion where the sympathetic efferent fiber synapses, continue back along a splanchnic nerve from the ganglion into the sympathetic trunk, move into a ...
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]
Autonomic nervous system, showing splanchnic nerves in middle, and the vagus nerve as "X" in blue. The heart and organs below in list to right are regarded as viscera. The autonomic nervous system has been classically divided into the sympathetic nervous system and parasympathetic nervous system only (i.e., exclusively motor).
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 ...
Notable medieval examples include: Otto the Great (d. 973), whose body was buried in Magdeburg separately from his entrails, which were interred at Memleben. [3]Henry I (d. 1135), whose body was buried in Reading Abbey, but his heart, along with his bowels, brains, eyes & tongue, is interred at the Cathedral in Rouen, Normandy.
The visceral pleura (from Latin: viscera, lit. 'organ') covers the lung surfaces and the hilar structures and extends caudally from the hilum as a mesentery-like band called the pulmonary ligament. Each lung is divided into lobes by the infoldings of the pleura as fissures.
