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 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 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 the difference between a fissure and a sulcus?
A fissure is a deep groove or cleft, while a sulcus is a shallower groove. Fissures are usually larger and more prominent than sulci. In the brain, fissures are deeper grooves that divide the brain into lobes, while sulci are smaller grooves found within the lobes.
The coronary sulcus is a groove that?
The function of the coronary sulcus is to ultimately transfer blood between the cardiac muscles. The coronary sulcus is located between the ventricles and the atria. Reference: medical-dictionary.thefreedictionary.com
What are the creases in the brain called?
If we didn't have wrinkles, our brains would be the size of a pillowcase. As brains grow, they fold in on themselves. It's said as you learn, your brain gets more wrinkles. I don't know if it's true, though.
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
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 is the line that divides the motor and sensory cortices called?
Data indicate a marked variability and suggest that motor and sensory cortices overlap and are not divided in a simple manner by the central sulcus. The central sulcus is the word that you are looking for.
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).
What is a raised area on the Cerebral Cortex?

What are the depressions between the convolutions of the cerebrum?
The answer is sulcus.
Where in a human body can you find a Sulcus and a Gyrus?
In the brain. A sulcus refers to a groove or furrow in the cerebral cortex, while a gyrus is a ridge or bump on the brain's surface. They are both part of the cerebral cortex's folded structure, which allows for more surface area within the limited space of the skull.
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 is difference between suture and sulcus?
Suture is a fibrous connective tissue joint between two or more structures (e.g. bones in the brain). For example, there is a sagittal suture between the two parietal bones of the skull. Sulcus is the fissure on the surface of the brain which surrounds the gyri. For example, there is a central sulcus which separates the frontal and parietal lobes of the cerebral cortex.
Primary visual cortex is located in the postcentral gyrus?
The primary visual cortex is not located in the postcentral gyrus; rather, it is situated in the occipital lobe, specifically in the calcarine sulcus. The postcentral gyrus, on the other hand, is primarily associated with the primary somatosensory cortex, which processes sensory information from the body. The primary visual cortex is crucial for visual processing and perception.
