Sulcus....
The groove that divides the cerebrum in two hemispheres is called the longitudinal fissure. It separates the left and right hemispheres of the brain and is where the corpus callosum connects the two hemispheres.
Inter hemispheric fissure.
The deepest groove in the cerebrum is the lateral sulcus, also known as the Sylvian fissure. It separates the temporal lobe from the frontal and parietal lobes. This fissure is important for separating the different functional zones of the brain.
The brains of many animals (including humans) are partially divided by a deep central groove, running from the front of the head to the back. The portions of the cerebrum to each side of the groove form the left and right hemispheres.
The deep groove that divides the right and left hemispheres of the cerebrum is the longitudinal fissure. It houses the falx cerebri, a fold of dura mater that helps separate the two hemispheres. The corpus callosum is a structure that connects the two hemispheres and allows for communication between them.

sulcus
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.
Sulcus
The cerebrum is divided into the right and left hemispheres by a deep groove called the longitudinal fissure. This fissure runs along the midline of the brain, separating the two hemispheres. Each hemisphere is responsible for different functions and processes information in distinct ways, contributing to the brain's overall functionality.
Echinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers. For example, sea stars or "star fish" have an ambulacral groove on their oral side (underside). This ambulacral groove extends from the mouth to the end of each ray or arm. Each groove of each arm in turn has four rows of hollow tube feet that can be extended or withdrawn. Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray.
The costal groove is a feature found on the inner surface of the ribs, serving as a protective channel for the intercostal nerves and blood vessels. It helps to shield these structures as they run along the rib cage, ensuring they remain safeguarded during movements and activities. Additionally, the groove aids in the attachment of muscles involved in respiration by providing a surface for muscle attachment.
