Anatomy

Major organs
Surface projections of major organs of the torso, using the vertebral column and rib cage as main reference sources.

Most critical organs are housed within the torso. In the upper chest, the heart and lungs are protected by the rib cage, and the abdomen contains most of the organs responsible for digestion: the stomach, which breaks down partially digested food via gastric acid; the liver, which respectively produces bile necessary for digestion; the large and small intestines, which extract nutrients from food; the anus, from which fecal wastes are egested; the rectum, which stores feces; the gallbladder, which stores and concentrates bile; the kidneys, which produce urine, the ureters, which pass it to the bladder for storage; and the urethra, which excretes urine and in a male passes sperm through the seminal vesicles. Finally, the pelvic region houses both the male and female reproductive organs.

Major muscle groups

The torso also harbours many of the main groups of muscles in the body, including the:

Nerve supply

The organs, muscles, and other contents of the torso are supplied by nerves, which mainly originate as nerve roots from the thoracic and lumbar parts of the spinal cord. Some organs also receive a nerve supply from the vagus nerve. The sensation to the skin is provided by:

  • Lateral cutaneous branches
  • Dorsal cutaneous branches
  • Distribution of cutaneous nerves. Ventral aspect. Dorsal and lateral cutaneous branches labeled at center right.

gollark: How would meme investment work?
gollark: It might also be interesting to try and *not* base it vaguely on real-world stock markets, so does anyone have ideas there?
gollark: I guess upvotes aren't that great either, but it's better than currently...
