Visceral vs. Somatic
Visceral refers to internal organs in the body. This may include those around the chest, such as the heart and lungs or those within the abdomen such as the liver, intestines and pancreas.
The visceral area may be said to be around the gut in a figurative sense.
Somatic is part of the body that is in the periphery. This is made up of, the skin, skeletal muscle and sensory organs. It is the part of the body that is in contact with the environment surrounding the body.
Both these terms refer to the anatomical structure of the body.
