If anything is sacred, the human body is sacred.

Of the human form especially, it is so great it must never be made ridiculous . . . Exaggerations will be revenged in human physiology.

Leonardo's dedication to portraying the outward manifestations of inner emotions would end up driving not only his art but some of his anatomical studies. He needed to know which nerves emanated from the brain and which from the spinal cord, which muscles they activated, and which facial movements were connected to others.

He needed to know which nerves emanated from the brain and which from the spinal cord, which muscles they activated, and which facial movements were connected to others. He would even try, when dissecting the brain, to figure out the precise location where the connections were made between sensory perceptions, emotions, and motions. By the end of his career, his pursuit of how the brain and nerves turned emotions into motions became almost obsessive. It was enough to make the Mona Lisa smile.

Leonardo's initial anatomy studies of 1489 focused on human skulls. He started with a skull that had been sawed in half, top to bottom (fig. 60). Then the front of the left half was sawed off. His groundbreaking technique of drawing the two halves together made it easy to see how the inner cavities were positioned relative to the face. For example, the frontal sinus, which Leonardo is the first person to correctly depict, is shown to rest just behind the eyebrow.

All of the other muscles he studied acted by pulling rather than pushing a body part, but the tongue seemed to be an exception. This was true in humans and in other animals. The most notable example is the tongue of the woodpecker. Nobody had drawn or fully written about it before, but Leonardo with his acute ability to observe objects in motion knew that there was something to be learned from it.

Many of the figures in his preparatory drawings are nude; he had come to believe in Alberti's advice that an artist should build a picture of a human body from the inside out, first conceiving of the skeleton, then the skin, then the clothing.

Leonardo was not content merely to measure every aspect of every body part. In addition, he felt compelled to record what occurs when each of these parts moves.

After his excursion into comparative anatomy, Leonardo proceeded to delve deeper into the mechanisms of humans as they smile or grimace (fig. 111). He focused on the role of various nerves in sending signals to the muscles, and he asked a question that was central to his art: Which of these are cranial nerves originating in the brain, and which are spinal nerves?

Every part will be drawn, using all means of demonstrations, from three different points of view; for when you have seen a limb from the front, with any muscles, sinews, or veins which take their rise from the opposite side, the same limb will be shown to you in a side view or from behind, exactly as if you had that same limb in your hand and were turning it from side to side until you had acquired a full comprehension of all you wished to know.

En otros movimientos de los labios participan músculos distintos, como los «que llevan los labios a un punto; otros que los aplastan, otros que los vuelven hacia atrás; otros que los enderezan; otros que los tuercen y otros, al final, que los devuelven a su primera posición».

The human body is strangely made and sometimes it pays not to think about it too closely.

it has never been in my power to study anything,—mathematics, ethics, metaphysics, gravitation, thermodynamics, optics, chemistry, comparative anatomy, astronomy, psychology, phonetics, economics, the history of science, whist, men and women, wine, metrology, except as a study of semiotic.

Most men would never tell a girl her Pikachu smells like a crab cake. It's just not done. But they would have no qualms about telling their guy friends. Similarly, if you're a guy and you pull your pants down, and the girl you're with immediately stats text messaging her friends, you have a small penis. Are You There Vodka? It's Me, Chelsea

...the twinkling anatomy of Orion and his skymates...

Comparative anatomy teaches us that man resembles frugivorous animals in every thing, and carnivorous in nothing; he has neither claws wherewith to seize his prey, nor distinct and pointed teeth to tear the living fibre... It is only by softening and disguising dead flesh by culinary preparation, that it is rendered susceptible of mastication or digestion; and that the sight of its bloody juices and raw horror does not excite intolerable loathing and disgust.

Life is pharmaceutical from head to cuticle.

The sound-producing organs of their terrestrial ancestors, their larynxes, evolved to make louder and more complex sounds. For instance, dolphins have two nasal passages and two sets of sound-producing organs and can simultaneously produce two different sounds. The

Recent scientific research has reinforced the findings of people like Otnow and Athens by demonstrating that a traumatic upbringing can actually alter the anatomy of a person's brain. Brain scans performed on severely abused children have found that specific areas of the cortex—related not just to the intelligence but to the emotions—never develop properly, leaving them incapable of feeling empathy for other human beings.

There are only two ways a person can die. Their heart or their lungs.
