Motor and sensory homunculi

Sensory and motor homunculi. Computer artwork of a motor homunculus (left) and a sensory homunculus (right). Parts of the body are sized according to how much space the brain gives to processing sensory information about that part of the body (sensory homunculus) or to controlling the movement of that part of the body (motor homunculus)

Blood vessels of chest and neck

Blood vessels of the chest and neck, historical anatomical artwork. The thoracic (chest) cavity has been dissected in this anterior (front) view to reveal part of the aorta, the largest artery in the human body. The aorta forms an arch (central, u-shaped) just above the heart, and then descends through the thorax and diaphragm (bottom, dumbbell-shaped) into the abdomen. The carotid arteries emerge from the aortic arch and carry blood up the neck to the head and brain. The lungs have been removed here but the bronchi (centre, grey/white) can be seen next to the aortic arch. This illustration is taken from the 19th century French textbook The Atlas of Human Anatomy and Surgery by J. M. Bourgery and N. H. Jacob
