What is sagittal and Midsagittal?
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 that is exactly in the middle of the body; it passes through midline structures such as the navel and the spine.

Why is it called midsagittal plane?
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.

temporal lobeThe medial (closer to the middle of the brain) temporal lobe contains the hippocampus, a region of the brain important for memory, learning and emotions.
What is the midline of the brain called?
Gross Anatomy: Cerebellum The cerebellum consists of 2 hemispheres, connected by a midline structure called the vermis. In contrast to the neocortex of the cerebrum, the cerebellar cortex has 3 layers: molecular, Purkinje, and granular.
How a midsagittal section differs from a sagittal section?
Sagittal vs Midsagittal A sagittal plane is a hypothetical plane that is used to divide the body along a vertical axis. Midsagittal is a hypothetical plane that divides the body into two equal halves along the vertical axis, the right half and the left half.
What is a section in anatomy?
Medical professionals often refer to sections of the body in terms of anatomical planes (flat surfaces). These planes are imaginary lines – vertical or horizontal – drawn through an upright body. The terms are used to describe a specific body part.
What is the name of a plane that lies at a right angle to the midsagittal plane?
What is the name of a plane that lies at a right angle to the midsagittal plane? Oblique plane.
What is the midsagittal section of the brain?
A midsagittal section of the brain shows the cerebrum, cerebellum and the brainstem. The brain is divided into the prosencephalon, mesencephalon, and rhompbencephalon. The prosencephalon is further divided into the telencephalon (cerebral hemispheres) and Diencephalon (thalami, neurohypophysis, pineal body,..etc).
What is the name of the grooves that divide the cerebral cortex?
Sulci are small grooves that divide and define gyri; large grooves, called fissures, divide the cerebral cortex into lobes, and also the cerebrum into the right and left cerebral hemispheres along the midsagittal plane. The fissure involved in this division is called the medial longitudinal fissure. From the midsagittal section of the brain both white and gray matter can be observed, as well as important spaces such as the third and fourth ventricles.
What is the name of the structure that is located between the cerebrum and the brainstem?
Diencephalon, brainstem and related structures. The diencephalon is part of the “old brain” lying between the cerebrum and the brainstem and is composed of the thalamus, the hypothalamus, and the epithalamus. These can be seen in a midsagittal aspect upon sectioning of the third ventricle. The brainstem is the “bridge” between ...
What are the three major parts of the brain?
The midsagittal section of the brain shows the three major parts of the brain, which are the cerebrum, cerebellum, and brainstem. These brain parts are marked with visible gross features like the gyri (singular: gyrus) and sulci (singular: sulcus) of the cerebrum. They are each also divided into subparts or regions for simplified localization ...
What is the name of the fold of the cerebrum that separates the cerebrum from the brain?
The cerebellum lies posterior to the brainstem and is separated from the cerebrum by a fold of dura mater called the tentorium cerebelli . Overview of the cerebellum. The cerebellum consists of two hemispheres separated by the medially positioned vermis. The cerebellum also has superior and inferior surfaces.
What are the subparts of the brainstem?
They are each also divided into subparts or regions for simplified localization of structures, for example, the brainstem is composed of the midbrain, pons and medulla oblongata, while the cerebrum is divisible into lobes.
What is the surface of the cerebellum?
The surface of the cerebellum is marked by a series of fissures that run more or less parallel to one another. The fissures subdivide the surface of the cerebellum into narrow leaf-like bands or folia. The long axis of the majority of folia is approximately transverse.
What is the midsagittal plane?
The midsagittal plane or median plane divides the body into two parts. It vertically splits any object or organism into two relatively equal halves – left and right. In humans, each of the two bisected divisions includes half of the head, thorax, abdomen and genitals, one arm and one leg.
What causes a left and right midsagittal section to be irregular?
Craniomaxillofacial (CMF) deformities are another cause of irregularities between left and right midsagittal sections. Usually the result of facial traumas or genetic irregularities, facial dissymmetry can cause further problems such as respiratory or visual difficulties. In cases of reconstructive craniomaxillofacial surgery, specialists try to return trauma victims to the premorbid (pre-trauma) midsagittal plane; in cases of genetic deformities, to a normal anatomical structure.

Anatomical position. The two mirrored parts are referred to as left or right midsagittal sections, where left and right corresponds to the left and right of the subject, not the point of view of the person looking at, for example, a computed tomography image.

What is supernumerary anatomy?
Supernumerary anatomy describes situations where the body contains an extra part, organ or part of an organ. These additions can either be symmetrical, such as in the case of Myrtle Corbin (pictured below) or asymmetrical. Usually, supernumerary anatomy is the result of disruption during embryonic development through genetic mutations. Mutations in the fetus are sometimes caused by drugs such as thalidomide when taken by the mother during pregnancy.
