The nervous system allows us to move, feel, and think, and it is involved in nearly all of the functions of the human body. Nerves communicate signals between the brain and muscles, allowing us to move our hands and feet. This book discusses the development and organization of this diverse system, its functions, and potential injuries.

Down syndrome is a developmental disorder caused by the presence of an extra copy of chromosome 21. This extra genetic material causes changes in the production of various proteins, such as enzymes and cell adhesion molecules, which can disrupt metabolic pathways and cause defects in organ development. This title explains this genetic disease.
