What are the directions of the brain?
The directions rostral, caudal, ventral, and dorsal change depending on the relative position of a structure to the midbrain. Above the midbrain, the orientation of the these directions is similar to that used with animals whose nervous system in linear in arrangement.
What are the planes of the brain?
The brain is can be cut on any of these planes and are named the coronal plane, the horizontal plane or the sagittal plane. The coronal plane, horizontal plane and sagittal plane are shown in the figure on the right. The coronal plane is also called the frontal plane.
What is directional term of brain?
Three directional planes exist in the brain: rostral/caudal, dorsal/ventral, and medial/lateral.
Why are directional and locational terms important to neuroscience?
Directional terms are used to locate one structure, usually in relation to another structure. Some terms, like dorsal or ventral, are relative to the axis of the central nervous system, so the direction these terms define changes if used for brain regions versus other body regions.
Whats the difference between directional terms and anatomical planes?
Anatomical directional terms are like the directions on a compass rose of a map. Like the directions, North, South, East and West, they can be used to describe the locations of structures in relation to other structures or locations in the body. Body planes are used to describe specific sections or regions of the body.
What is the coronal plane of the brain?
aka frontal plane, a coronal plane divides the brain into an anterior and posterior portion. It is created by slicing the brain parallel to the long axis of the body, and thus perpendicular to the floor in a person that is upright.
What is the purpose of directional terms?
directional terms: Directional terms are words used to describe the location of an anatomical structure by comparing its position to other structures within the body or within the orientation of the body itself.
What are directional terms used for?
Directional terms describe the positions of structures relative to other structures or locations in the body. Superior or cranial – toward the head end of the body; upper (example, the hand is part of the superior extremity).
What are the common planes and directional terms used to describe body parts and markings?
Up, Down, Side-to-Side: Directional Terms
| Anterior | At or near the front of the body (front view) |
|---|---|
| Posterior | At or near the back of the body (back view) |
| Midline | An imaginary vertical line that divides the body equally (right down the middle) |
| Lateral | Farther from midline (side view) |
| Medial | Nearer to midline (side view) |
What are directional planes?
Are frontal and coronal plane the same?
Anatomical terminology A coronal plane (also known as the frontal plane) is any vertical plane that divides the body into ventral and dorsal (belly and back) sections.
What are the directions and planes of section of the brain?
Directions and Planes of Section. Because the brain is a three dimensional structure, any location in the brain can be localized on three planes – the x, y and z planes. The brain is can be cut on any of these planes and are named the coronal plane, the horizontal plane or the sagittal plane. The coronal plane, horizontal plane…
What is the relative direction of the brain?
Directions and Planes of Section The relative position and direction of brain structures are described with special words. For example, we can say that the frontal lobe is “rostral” to the occipital lobe. Because the brain is a three dimensional structure, any location in the brain can be localized on three planes – the x, y and z planes.
How many planes of the brain are there?
The midsagittal plane equally divides the left and right hemispheres of the brain. A coronal section of the brain separates the front from the back. The images below show the three planes in which a brain can be sectioned. In addition, there are four possible views of the brain: lateral, medial, dorsal, and ventral.
What planes of the brain are visible during sectioning?
When sectioning (cutting) the brain, which planes are visible is determined by the type of section. In the sagittal section (which is made parallel to the midline, dorsal to ventral) the rostral/caudal and dorsal/ventral planes can be seen.
