What is frontal operculum?
It has been suggested that an inferior frontal region, the frontal operculum (fO), is a critical node in a network controlling activity in other brain areas to perform the wide array of cognitive tasks of which humans are capable (1–3).
Where is the frontal operculum located?
the frontal operculum begins at the anterior ramus of the lateral fissure and extends to the inferior portions of the precentral gyrus, encompassing the pars triangularis and opercularis of the inferior frontal gyrus.
What are the insula and frontal operculum?
In human brain anatomy, an operculum (Latin, meaning “little lid”) (pl. opercula), may refer to the frontal, temporal, or parietal operculum, which together cover the insula as the opercula of insula. The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus.
What is parietal operculum?
the parietal operculum lies between the inferior portion of the postcentral gyrus and posterior rami of the lateral fissure. The frontal and parietal regions are often grouped together as the frontoparietal operculum.
Which structures contributes to the operculum covering over the insula?
It is completely covered by its neighboring cortical structures—the frontal, the parietal and the temporal operculum. Macroscopically, the central sulcus of the insula divides it into an anterior and a posterior part (Fig.
What is the frontal sulcus?
The superior frontal sulcus is one of the major sulci of the frontal lobe, separating the superior frontal gyrus medially, from the middle frontal gyrus inferolaterally.
Where is the frontal lobe located anterior?
anterior cranial fossa
The frontal lobe resides largely in the anterior cranial fossa, lying on the orbital plate of the frontal bone. Its most anterior part is known as the frontal pole and extends posteriorly to the central (Rolandic) sulcus which separates it from the parietal lobe.
What lobe does insula belong?
temporal lobe
Where is the insula? The insula is a small region of the cerebral cortex located deep within the lateral sulcus, which is a large fissure that separates the frontal and parietal lobes from the temporal lobe.
What does the operculum do?
The operculum is a hard, plate-like, bony flap that covers the gills of a bony fish (superclass: Osteichthyes). It protects the gills and also serves a role respiration. Fish can acquire dissolved oxygen through pumping water over their gills by opening and closing their jaws and opercula.
What is the function of the operculum?
Operculum: The operculum is the bony flap that protects the gills from harm. It opens and closes to allow water to pass over the gills.
What is an operculum and what does it do?
