==Overview==
'''Torso''' is an anatomical term for the central part of the many animal bodies (including that of the human) from which extend the neck and limbs.  It is sometimes referred to as the '''trunk'''. The torso includes the [[thorax]] and [[abdomen]].

==Anatomy==
===Major organs===
Most critical [[Organ (anatomy)|organs]] are housed within the torso.  In the upper chest, the [[heart]] and [[lungs]] are protected by the [[Human rib cage|rib cage]], and the abdomen contains the majority of organs responsible for [[digestion]]: the  [[liver]], which respectively produces [[bile]] necessary for digestion; the [[large intestine|large]] and [[small intestine]]s, which extract nutrients from food; the [[anus]], from which [[human feces|fecal wastes]] are excreted; the [[rectum]], which stores [[feces]]; the [[gallbladder]], which stores and concentrates bile and produces [[chyme]]; the [[ureter]]s, which passes [[urine]] to the bladder; the [[urinary bladder|bladder]], which stores urine; and the [[urethra]], which excretes urine and passes [[sperm]] through the [[seminal vesicle]]s. Finally, the [[pelvic]] region houses both the male and female [[sex organs|reproductive organs]].

===Major muscle groups===
The torso also harbours many of the main muscle groups of the body, including the:
*[[pectoral muscles]]
*[[abdominal muscles]]
*[[lateral muscle]]

===Innervation===
The organs and muscles etc. are innervated by various nerves, mainly originating from [[thoracic]] vertebral segments. For instance, the [[cutaneous innervation]] is provided by:
* [[Ventral cutaneous branches]]
* [[Lateral cutaneous branches of torso|Lateral cutaneous branches]]
* [[Dorsal cutaneous branches]]
