viscera n : internal organs collectively (especially those in the abdominal cavity); "`viscera' is the plural form of `viscus'" [syn: entrails, innards]
Nounviscera (plural of viscus)
In anatomy, a viscus () (plural: viscera /ˈvɪsərə/) is an internal organ of an animal (including humans), in particular an internal organ of the thorax or abdomen. The viscera, when removed from a butchered animal, are known collectively as offal. Internal organs are also known as "innards", or less formally, "guts" (which may also refer to the gastrointestinal tract).
The adjective visceral is used for anything pertaining to the internal organs. Historically, viscera of animals were examined by Roman pagan priests like the haruspices or the augurs in order to divine the future by their shape, dimensions or other factors.

InnervationThe viscera are mainly innervated parasympathetically by the vagus nerve and sympathetically by the splanchnic nerves. The sensory part of the latter reaches the spinal column at certain spinal segments. Pain in any viscera is perceived as referred pain, more specifically pain from the dermatome (anatomy) corresponding to the spinal segment.
