Human abdomen: muscles in the spotlight
What it is and its main functions
The abdomen is the anterior trunk of the trunk of the animals. In vertebrates it is formed by the stomach, excretory apparatus, intestine and reproductive organs.
The abdomen of humans has, on the outside, a set of muscles, which serve to protect the internal organs against mechanical shock.
The abdomen is particularly well defined in mammals, from which it is separated from the thorax by the diaphragm.
In many arthropod animals such as arachnids and insects, the abdomen may be segmented.
