Male body sectioned. Side view of the male human body in natural colours, sliced through to show internal anatomy. This is part of the Visible Human Project. The brain is seen inside the skull; the tongue and nasal cavity are visible. Bones of the spine are separated by white discs; the spinal cord is seen. Muscles (brown) occur in the neck, back, leg and foot, and the thigh-bone (femur) is seen. Fat occurs in the skin around the abdomen and buttock. In the abdomen is the liver (brown) and digestive system (white). The Visible Human Project is a US project to archive both a male and female body. Each body is sectioned into slices. The project is for medical research and education.
