BIO 251 CH1 ANATOMY & PHYSIOLOGY QUESTIONS AND
ANSWERS GRADED A+ BY EXPERTS
Anatomical Position - correct answer -The body is erect with feet forward and slightly apart,
head and palms forward and thumbs pointing away from the body.
Sagittal Plane - correct answer -A vertical plane that divides the body into right and left parts. A
sagittal plane that lies directly on the midline is the Median plane, or Midsagittal Plane. All
other sagittal planes are Parasagittal (para=near) Planes.
Frontal Plane - correct answer -A vertical plane that divides the body into Anterior and
Posterior parts. Also called Coronal ("crown") Plane.
Transverse Plane - correct answer -Runs horizontally from right to left dividing the body into
Superior and Inferior parts. Also called a Cross section.
Oblique Section - correct answer -Cuts made diagonally between horizontal and vertical planes.
Cranial Cavity - correct answer -Part of the Dorsal Cavity that incases the brain.
Spinal Cavity (or Vertebral Cavity) - correct answer -Encloses the spinal cord. Part of the Dorsal
Cavity.
Viscera - correct answer -Internal organs
Thoracic Cavity - correct answer -Surrounded by the ribs and muscles of the chest, contains the
heart, esophagus, lungs, trachea and bronchi.
, Pleural Cavities - correct answer -A subdivision of the Thoracic Cavity, each contain a lung and
the mediastinum.
Pericardial Cavity - correct answer -Contained in the mediastinum, encloses the heart as well as
surrounding the esophagus, trachea and other thoracic organs.
Abdominopelvic Cavity - correct answer -Is separated from the Thoracic Cavity by the
diaphragm. Has two parts not divided by a muscular or membrane wall. Contains organs of the
digestive, reproductive and excretory systems.
Abdominal Cavity - correct answer -The superior portion of the Abdominopelvic Cavity contains
the intestines, liver, stomach, spleen, and pancreas. MNEMONIC: "I'd Love Some Spaghetti
Please"
Pelvic Cavity - correct answer -The inferior part of the Abdominopelvic Cavity contains the
urinary bladder, some reproductive organs, and the rectum.
Ventral Body Cavity - correct answer -Includes the Thoracic and Abdomino-pelvic Cavities.
Dorsal Body Cavity - correct answer -Includes the Cranial (brain) and Spinal (or Vertebral)
Cavities. Meninges membrane lines dorsal cavity.
Serosa (serous) Membrane - correct answer -A thin, double-layered membrane that covers the
walls of the ventral body cavity and the outer surfaces of the organs it contains.
Parietal Serosa - correct answer -The part of the membrane that lines the cavity walls. Usually
the furthest away from the organ, parie=wall.
