Cardinal Plane - The plane where the center of mass passes through. The three cardinal planes
in human body when he/she stands in the anatomical position frontal plane, sagittal plane and the transverse plane
*Frontal Plane (Coronal Plane) - The plane that cuts you down your side. It would cut you from your ear though your hip to your feet
Horizontal Plane - Any plane dividing the body into upper and lower portions, perpendicular to the vertical plane
*Median Plane (Midsagittal plane) - Passing directly along the midline of the body so that perfect right and left halves of the body is created
Oblique plane - Slanting plane that is not in any of the other planes
*Sagittal Plane (Lateral plane) - The plane that cuts right down the middle of your body
Spinous Plane - Horizontal plane transecting the body at the level of anterior superior iliac spine
Sternoxiphoid Plane - Horizontal plane transecting the body at the level of xiphisternal joint
Subcostal Plane - Horizontal plane transecting the body at the level of lower margin of the tenth rib
Suprasternal Plane - Horizontal plane transecting the body at the level of jugular notch
Thoracic Plane - Horizontal plane transecting the body at the level of the fourth intercostal space
Transpyloric Plane - Horizontal plane transecting the body at the level of the eighth intercostal space
*Transverse Plane (Axial Plane) - Plane that cuts across your stomach. It would cut you from one hip to the other
Umbilical Plane - Horizontal plane transecting the body at the level of the umbilicus
Vertical Plane - Any plane dividing the body into left and right portions, or front and back portions, perpendicular to the horizontal plane

*Main planes used


BODY CAVITIES

The cavities, or spaces, of the body contain the internal organs, or viscera. The two main cavities are called the ventral and dorsal cavities. The ventral is the larger cavity and is subdivided into two parts (thoracic and abdominopelvic cavities) by the diaphragm, a dome-shaped respiratory muscle.

Thoracic cavity - The upper ventral, thoracic, or chest cavity contains the heart, lungs, trachea, esophagus, large blood vessels, and nerves. The thoracic cavity is bound laterally by the ribs (covered by costal pleura) and the diaphragm caudally (covered by diaphragmatic pleura).

Abdominal and pelvic cavity - The lower part of the ventral (abdominopelvic) cavity can be further divided into two portions: abdominal portion and pelvic portion. The abdominal cavity contains most of the gastrointestinal tract as well as the kidneys and adrenal glands. The abdominal cavity is bound cranially by the diaphragm, laterally by the body wall, and caudally by the pelvic cavity.
The pelvic cavity contains most of the urogenital system as well as the rectum. The pelvic cavity is boundedcranially by the abdominal cavity, dorsally by the sacrum, and laterally by the pelvis.

Dorsal cavity - The smaller of the two main cavities is called the dorsal cavity. As its name implies, it contains organs lying more posterior in the body. The dorsal cavity, again, can be divided into two portions. The upper portion, or the cranial cavity, houses the brain, and the lower portion, or vertebral canal houses the spinal cord.


BODY LINE DICTIONARY

Anterior Median Line - It divides the anterior of the body into left and right portions (sides)
Axillary Line - Passing through the center of the axilla. It divides the body into an anterior and a posterior portion
Dorsoventral Axis - Any line perpendicular to the long axis of the body
Long Axis of the Body - Passes through the neck, thorax, abdomen, and pelvis. Around it the weights of the torso are most symmetrically distributed
Mid Clavicular Line (also mamillary line) - Passing through the center of the nipple
Parasternal Line - Passing midway between the midclavicular line and the border of the sternum
Posterior Median Line - It divides the posterior of the body into left and right portions (sides)
Sternal Line - Passing through the lateral border of the sternum
