The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).

Human body writing the influential book "De humani corporis fabrica". Anatomy advanced further with the invention of the microscope and the study of the cellular structure of tissues and organs. Modern anatomy uses techniques such as magnetic resonance imaging, computed tomography, fluoroscopy and ultrasound imaging to study the body in unprecedented detail. The study of human physiology began with Hippocrates in Ancient Greece, around 420 BC, and with Aristotle (384–322 BC) who applied critical thinking and emphasis on the relationship between structure and function. Galen (c. 126–199) was the first to use experiments to probe the body's functions. The term physiology was
