Human body to comparative physiology and ecophysiology. Most recently, evolutionary physiology has become a distinct subdiscipline. Human body The human body is the structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body. It comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. The study of the human body involves anatomy, physiology, histology and embryology. The body varies anatomically in known ways. Physiology focuses on the systems and organs of the human
Anatomical fugitive sheet survived. Jean Ruel, a French botanist and physician, published his own anatomical sheets in 1539. Andreas Vesalius published his anatomical work on the human body, ""De humani corporis fabrica"", four years later in 1543. His ""Tabulae anatomicae sex"" had appeared in 1538 showing skeletons and viscera, and differ substantially from the Ruel plates. Thomas Geminus, a pseudonym for Thomas Lambrit, was another engraver and printer, who freely copied the anatomical drawings of Vesalius, a practice which infuriated him into denouncing 'extremely inept imitators'. Geminus did however redraw and rearrange Vesalius' woodcut illustrations, choosing to use engraved copperplates, with which he
