●● Sagittal Plane.
Answer: A vertical plane that divides the body into right and left parts. A

Midsagittal Plane. All other sagittal planes are Parasagittal (para=near)
Planes.
●● Frontal Plane.
Answer: A vertical plane that divides the body into Anterior and
Posterior parts. Also called Coronal ("crown") Plane.
●● Transverse Plane.
Answer: Runs horizontally from right to left dividing the body into
Superior and Inferior parts. Also called a Cross section.
●● Oblique Section.
Answer: Cuts made diagonally between horizontal and vertical planes.
●● Cranial Cavity.
, Answer: Part of the Dorsal Cavity that incases the brain.
●● Spinal Cavity (or Vertebral Cavity).
Answer: Encloses the spinal cord. Part of the Dorsal Cavity.
●● Viscera.
Answer: Internal organs
●● Thoracic Cavity.
Answer: Surrounded by the ribs and muscles of the chest, contains the
heart, esophagus, lungs, trachea and bronchi.
●● Pleural Cavities.
Answer: A subdivision of the Thoracic Cavity, each contain a lung and
the mediastinum.
●● Pericardial Cavity.
Answer: Contained in the mediastinum, encloses the heart as well as
surrounding the esophagus, trachea and other thoracic organs.
●● Abdominopelvic Cavity.
