Sagittal plane is a vertical plane which passes from ventral (front) to dorsal (rear) dividing the body into right and left halves.
- The terms median plane or mid-sagittal plane are sometimes used to describe the sagittal plane running through the midline. This plane cuts the body into halves (assuming bilateral symmetry), passing through midline structures such as the navel and spine. It is one of the lines defining the right upper quadrant of the human abdomen.
- The term parasagittal is used to describe any plane parallel to the sagittal plane. In practice, such a section is often referred to simply as a "sagittal" view because viewing is achieved along the sagittal axis (see below). Due to the specific nature of its definition, only one true sagittal plane exists, and it corresponds to the "mid-sagittal" view. Be aware that the term "sagittal view" may be applied to any parasagittal section as well as the sagittal plane, as the parasagittal and sagittal axes are identical (parallel to the sagittal plane).
Specific named parasagittal planes include:
The term sagittal is derived from the Latin word Sagitta, meaning "arrow". An image of an arrow piercing a body and passing from front (anterior) to back (posterior) on a parabolic trajectory would be one way to demonstrate the derivation of the term. Another explanation would be the notching of the sagittal suture posteriorly by the lambdoidal suture —similar to feathers on an arrow.
- Sagittal axis is the axis perpendicular to the sagittal plane, i.e., the sagittal axis is formed by the intersection of the coronal and the transversal planes.
- Coronal axis or frontal axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes.

Affects one in three adults
Affecting about 35 percent of all adults in the United States according to the CDC, metabolic syndrome contributes to weight gain, by causing a state of internal starvation called metabolic starvation. This in turn leads to increases hunger, sugar cravings and increased portions leading to overeating and weight gain.
Cause and effect misunderstood
Since we traditionally thought that the portion control (which in turn was attributed wrongly to poor will power)is the cause of weight gain, rather than the effect of this metabolic starvation, all our traditional ideas about cause and effect of obesity were not only wrong but lead to the “blame the victim” attitude when it comes to obesity.
Secret of weight gain revealed
Secret of weight gain, and metabolic syndrome revealed - it has been recently proven that metabolic syndrome, and the weight gain itself are caused by a process called insulin resistance. Check your metabolic syndrome risk using the free Metabolic syndrome meter. Watch this amazing Ted Med video that reveals the secret of weight loss - Stop blaming the victim for obesity
