Buccinator muscle Buccinator muscle The buccinator ( ) is a thin quadrilateral muscle occupying the interval between the maxilla and the mandible at the side of the face. It forms the anterior part of the cheek or the lateral wall of the oral cavity. It arises from the outer surfaces of the alveolar processes of the maxilla and mandible, corresponding to the three pairs of molar teeth; and behind, from the anterior border of the pterygomandibular raphé which separates it from the constrictor pharyngis superior. It is attached upon the buccinator crest as far forward as the first molar tooth. The fibers
Human body writing the influential book "De humani corporis fabrica". Anatomy advanced further with the invention of the microscope and the study of the cellular structure of tissues and organs. Modern anatomy uses techniques such as magnetic resonance imaging, computed tomography, fluoroscopy and ultrasound imaging to study the body in unprecedented detail. The study of human physiology began with Hippocrates in Ancient Greece, around 420 BC, and with Aristotle (384–322 BC) who applied critical thinking and emphasis on the relationship between structure and function. Galen (c. 126–199) was the first to use experiments to probe the body's functions. The term physiology was
