Where is the coronal plane

Anatomical Planes in a Human : There are three basic planes in zoological anatomy: sagittal, coronal, and transverse. A human in the anatomical position, can be described using a coordinate system with the Z-axis going from front to back, the X-axis going from left to right, and the Y-axis going from up to down.

By imaging a patient in standard anatomical position, a radiologist can build an X-Y-Z axis around the patient to apply body planes to the images. Individual organs can also be divided by planes to help identify smaller structures within that organ.

Body planes are used to describe anatomical motion in the X-Y-Z coordinate system that the body moves through. Anatomical change during embryological development is also described and measured with body planes. For example, during human embryonic development the coronal plane is horizontal, but becomes vertical as the embryo develops into a fetus.

In comparative embryology, body planes provide a basis for comparing the ways in which different types of organisms develop anatomically within the womb. Learning Objectives Identify the three basic anatomical reference planes. Horizontal cuts are made as if you were slicing a hamburger bun or bagel.

The sagittal plane divides the right and left side of the brain into parts. The midsagittal plane would divide the right and left sides of the brain into two equal parts, like cutting down the middle of a baked potato before you put on the toppings.

The figures below show the human brain in the three planes of section on "synthetic MR" images produced by BrainWeb : Coronal Section. Try it! The thoracic cavity is bound laterally by the ribs covered by costal pleura and the diaphragm caudally covered by diaphragmatic pleura.

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 bounded cranially by the abdominal cavity, dorsally by the sacrum , and laterally by the pelvis. 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.
