Atlas A (1)

• In the anatomical position, the person is supposed to be standing upright, with their feet flat on the floor. They should face the observer and have their arms by their side with palms facing forward and thumbs pointing away from the body.
• The Body Planes are Frontal Plane (Coronal Plane), Sagittal Plane, and Transverse Plane.
• Frontal Plane: divides the body into anterior and posterior parts (front and back)
• Transverse Plane: divides the body into superior and inferior parts (top and bottom)
• Sagittal Plane: divides the body into right and left parts. There are two subsections under sagittal plane; midsagittal and parasagital.
• Midsagittal goes down the midline of the body.
• Parasagittal is off of the midline.
• Body Cavities: The spaces inside the body that are not part of the body wall. They include the Dorsal (back) Cavity and the Ventral (front) Cavity.
• The Dorsal Cavity includes the Cranial Cavity (brain) and the Vertebral Canal (spinal cord).
• The Ventral Cavity includes the Thoracic Cavity and the Abdominopelvic Cavity. The Thoracic Cavity includes the Pleural (lungs) and the Pericardial (heart), while the Abdominopelvic Cavity includes the Abdominal (digestive organs, spleens, kidneys) and Pelvic (bladder, rectum, reproductive organs)
