Muscles and nerves of a developing lizard

Muscles and nerves of a developing lizard
After 12 days of incubation, this embryo of Madagascar ground gecko (Paroedura pictus) shows the developing main nerves extending out from the central nervous system (grey) and the building-blocks of the muscles, including the heart (red). Later on the blocks of muscle will divide into the many more individual muscles in charge of moving the body, and the nerves will branch to extend into almost every part of its body.
