Famous quotes containing the word physiology:
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”

“The world moves, but we seem to move with it. When I studied physiology before ... there were two hundred and eight bones in the body. Now there are two hundred and thirty- eight.”

“I have more in common with a Mexican man than with a white woman.... This opinion ... chagrins women who sincerely believe our female physiology unequivocally binds all women throughout the world, despite the compounded social prejudices that daily affect us all in different ways. Although women everywhere experience life differently from men everywhere, white women are members of a race that has proclaimed itself globally superior for hundreds of years.”
—Ana Castillo (b. 1953)
