Instant Anatomy is a reference book for students of human anatomy. It includes several schematic diagrams and pictures, many of which are drawn by Whitaker himself. The intention is to simplify the regions of anatomy, thereby making it easier to remember parts, creating an 'instant' summary. The book is divided up into sections for arteries, veins, lymphatics, autonomic nervous system, cranial nerves, peripheral nerves, dermatomes and cutaneous nerve distribution, muscles, joints, ossification times, foramina - skull and spine, spaces other than skull and spine, position of structures according to vertebral levels and pharyngeal derivatives. There is also an accompanying website, which has several more pictures, podcasts and video teaching. It is clear from the 'guestbook' of the website that it is used and appreciated by many people all around the world in their studies of anatomy.
