a sulcus is a depression or a groove found on the surface of an organ or tissue,as on the surface of the brain separating adjacent convultion. While a gyrus is one of the prominent rounded elevations between the sulci or grooves on the surface of the hemispheres of the brain.

What is the difference between a fissure and a sulcus?
Fissure is deeper than a sulcus
What are shallow grooves that exist in the brain?
You have sulci ( singular is sulcus) and gyri ( singular is gyrus) in the surface of the brain. By this mechanism you have the surface area of the brain, vastly increased.
The motor cortex sits just posterior of the central fissure in the frontal lobes whereas the somatosensory cortex sits next to the central fissure in the parietal lobes of the cerebral cortex?
Wrong. The motor cortex is the prominent gyrus that is ancterior to the central sulcus. The Somatosensory cortex is the prominent gyrus that is posterior to the central sulcus.
What is the difference between gyri and sulci?
Parts of the Brain: Cerebrum-largest part of brain, 7/8 total mass of the brain. * 2 cerebral hemispheres: # ridges- gyri # grooves- sulci *Gyrus(gyri)-is a ridge on the cerebral cortex. Folds on the brain material. Many ridgescalled convolutions, or gyri, or gyrus, separated by grooves, mark the cerebrum's surface. *Sulcus(sulci)-shallow grooves on the brain. Generally, a shallow to somewhat deep groove is called a sulcus, or sulci, and a very deep groove is called a fissure.
What is a raised area on the Cerebral Cortex?
A Ridge/Hill is called a Gyrus (pl Gyri) and a cleft/valley is called a Sulcus (pl Sulci). Some of the Gyri and Sulci are individually named for example look at the cerebrum from a lateral view. You should see one fairly distinct vertical sulcus roughly in the middle of the brain (it will not be straight but reasonably obviously vertical. This is called the Central Sulcus. The gyrus immediately in front of that sulcus is called the Precentral Gyrus and the one behind is called the Postcentral Gyrus. The precentral is where the Primary Motor Cortex is seen and the postcentral is where the Somatosensory Cortex is seen. There are many other named sulci and gyri but it is too complicated to describe them without an image.
What separates the precentral and postcentral gyrus?
the central sulcus!
What are the two main gyri and sulci that can be seen on the most superior portion of the brain?
Superior frontal gyrus, superior temporal gyrus, superior frontal sulcus, superior temporal sulcus
What is the difference between a fissure and a sulcus?
Fissure is deeper than a sulcus
The layer of the meninges that closely follows every gyrus and sulcus is the?
pia matter
What bis a bump in the cerebral cortex called?
a gyrus is a fold of neural tissue, a sulcus is a groove
What area is posterior to the central sulcus?
Postcentral gyrus, or the parietal lobe [Edit: The postcentral gyrus is posterior to the central sulcus, not anterior. The primary motor cortex is located directly anterior to the central sulcus.]
What are shallow grooves that exist in the brain?
You have sulci ( singular is sulcus) and gyri ( singular is gyrus) in the surface of the brain. By this mechanism you have the surface area of the brain, vastly increased.
Where in a human body can you find a Sulcus and a Gyrus?
The brain. Sulci are the valleys, gyri are the hills when looking at the surface anatomy
What is the difference between supracallosal gyrus and indusium griseum?
They are simply the same thing. Supracallosal gyrus is the another name for indusium griseum. It's also called as gyrus epicallosus.
The motor cortex sits just posterior of the central fissure in the frontal lobes whereas the somatosensory cortex sits next to the central fissure in the parietal lobes of the cerebral cortex?
Wrong. The motor cortex is the prominent gyrus that is ancterior to the central sulcus. The Somatosensory cortex is the prominent gyrus that is posterior to the central sulcus.

What is the term for a ridge of the cerebral cortex?
A ridge or elevation of the cerebral cortex is a gyrus (plural gyri). The infoldings are sulci (singular sulcus).
