What does Parasagittal plane mean in anatomy?
Parasagittal plane—A vertical cut that is off-center that separates the left of the specimen from the right in unequal portions. It does not matter whether it is the left side or the right side that is larger, as long as they are not equal.
What is the Parasagittal section?
The term parasagittal is used to describe any plane parallel or adjacent to a given sagittal plane. Specific named parasagittal planes include: The midclavicular line crosses through the clavicle. Lateral sternal and parasternal planes.
What is sagittal plane and parasagittal plane?
The sagittal or lateral plane dives the body into left and right halves and is an x-z plane. Technically, the sagittal or median plane goes right through the middle between the body’s left and right halves. Planes parallel the sagittal planes are called parasagittal planes. They are x-z planes.
What is the difference between sagittal and parasagittal?
A sagittal plane runs vertically from top to bottom (and front to back), and it divides the body into a left and right portion. A “parasagittal” plane is any sagittal plane that does not run perfectly down the midline of the body.
How many Parasagittal planes are there?
The nine divisions are part of parasagittal and two transverse planes of body-centered around the navel. These divisions are important anatomically to determine the location of the organ within the abdomen and pelvic area.
What is sagittal and coronal?
Coronal Plane (Frontal Plane) – A vertical plane running from side to side; divides the body or any of its parts into anterior and posterior portions. Sagittal Plane (Lateral Plane) – A vertical plane running from front to back; divides the body or any of its parts into right and left sides.
What is the definition of Parasagittal?
Medical Definition of parasagittal : situated alongside of or adjacent to a sagittal location or a sagittal plane.
How many Parasagittal planes are in the human body?
What cavity encases the brain?
Together the cranial cavity and spinal (or vertebral) cavity can be referred to as the dorsal body cavity. In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity encloses the spinal cord.
Where is the posterior?
Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).
What is cardinal plane?
The CARDINAL PLANES There are three basic planes used in anatomical description: The frontal, transverse and sagittal planes (Figure 1). These cardinal planes intersect at the body’s theoretical center of gravity or center of mass.
Where is the parasagittal region of brain?
This narrow arc of white matter is situated between the medial cerebral cortex that curves around the lateral edge of the pars marginalis and the lateral cerebral cortex that lies just medial to the parenthesis of the postcentral sulci.
What are the 4 anatomical planes?
The main anatomical planes of the human body, including mid-sagittal or median (red), parasagittal (yellow), frontal or coronal plane (blue) and transverse or axial plane (green)
What is an anatomical plane?
Glossary of medicine. An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and animal anatomy , three principal planes are used: The sagittal plane or median plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture.
What are planes in anatomy?
An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and animal anatomy , three principal planes are used: The sagittal plane or median plane ( longitudinal, anteroposterior ) is a plane parallel to the sagittal suture.
Which plane is the frontal plane in anatomy?
The coronal plane or frontal plane ( vertical) divides the body into dorsal and ventral (back and front, or posterior and anterior) portions. The transverse plane or axial plane ( horizontal) divides the body into cranial and caudal (head and tail) portions.
