A surgical incision is a cut made through the skin and soft tissue to facilitate an operation or procedure.Often, multiple incisions are possible for an operation. In general, a surgical incision is made as small and unobtrusive as possible to facilitate safe and timely operating conditions and recovery.
For example, if a person is holding a bowl of soup in one hand, the hand is "supinated" and the thumb will point away from the body midline and the palm will be superior; if the hands are typing on a computer keyboard, they will be "pronated" with the thumbs toward the body midline and the palms inferior.
The Oxford English Dictionary indicates that sagittal in the sense of the sagittal suture along the vertex of the skull pre-dates other anatomical usage. [7] Sagittal axis or anterior-posterior axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes
A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes) are parallel to it.
This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal.
The sagittal suture, also known as the interparietal suture and the sutura interparietalis, [citation needed] is a dense, fibrous connective tissue joint between the two parietal bones of the skull. The term is derived from the Latin word sagitta , meaning arrow .
Vertical lines: Midline, lateral sternal line, parasternal line and midclavicular line. Horizontal lines: Level of the sternal angle, and zipho-sternal line. Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location.
Whether in reference to the anatomy of the human or other members of the Bilateria, the median plane, also called the midsagittal plane and related terms, is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side. The term parasagittal plane ...
