Brain fissures are convolutions in the structure of the brain that form valleys between folds. The valleys are called fissures or sulci (plural of sulcus), and lie between the raised folds called gyri (singular gyrus).
Many brain features are identified with fissures, including Broca's fissure, the Fissure of Sylvius, the central (Rolando's) fissure, and the hippocampal fissure.

What is Function of fissure in skull?
Fissures in the skull allow for the passage of nerves and blood vessels between different regions of the brain. They also provide flexibility for the skull during childbirth and growth. Additionally, fissures help to separate and protect vulnerable areas of the brain from damage.
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.
What does the Sylvian fissure do?
The Sylvian fissure is a prominent landmark on the brain's surface that separates the frontal lobe from the temporal lobe. It plays a critical role in separating and defining these two major regions of the brain, which are involved in functions like motor control, language processing, and memory.
Deep sulcus in the brain?
A deep sulcus in the brain refers to a prominent groove or indentation in the cortical surface. Sulci are normal features of the brain and play a role in increasing the surface area for more efficient processing of information. However, abnormally deep sulci can sometimes be indicative of certain neurological conditions or developmental abnormalities.
What purpose do convolutions fissures and folds serve in relationship to the brain?
The Function of Gyri (pl.Gyrus) One of the prominent rounded elevation that form the cerebral hemispheres, each consisting of an exposed superficial portion and a portion hidden from view in the wall and floor of the sulcus.
Definition of Brain fissures?
The hills in the surface of the brain are called gyri (singular: gyrus), and the valleys are called sulci (singular: sulcus). Very deep sulci are called fissures. When locations are described in the brain, major sulci and gyri are often used as reference points, like familiar landmarks.Source: Sparknotes

Is brain fissures dangerous?
Brain fissures are natural folds in the brain that help increase its surface area. They are not typically considered dangerous. However, certain conditions such as stroke, brain injury, or a congenital malformation may impact brain fissures and require medical attention.
What is a sentence for the word fissures?
"Most surface cracks caused by earthquakes are not the wide, deep fissures shown in disaster movies." "The fissures within the brain contain some of the most important cerebral regions." "The ice of the frozen Arctic Ocean is split by fissures called crevasses."
What is Function of fissure in skull?

What is frontal cortical atrophy as described with mild asymmetry at the level of the sylvan fissures?
Break it down into less intimidating portions: Frontal cortical- front half of the brain Sylvan fissures- these particular "wrinkles" in the brain seperates the frontal and temporal lobes Effectively the front portion of the brain is wasting away and there is an uneveness in the brain in the area that seperates the front and back portions. Best of luck for you and yours. That's a fairly rough Dx.

Inwards folds of cerebral tissues?
The inward folds of cerebral tissue are called sulci. These are narrow fissures that separate adjacent convolutions of the brain.
How do you say the word fissures?
"Fissures" is pronounced as "FI-sherz."
What is the definition of Hydrocephalus?
The definition of the word "hydrocephalus" is a medical condition in which fluids accumulate on the brain. The condition is sometimes referred to as "water on the brain".
