Latin: operculum - lid
English:
Definition[Bearbeiten]
The term operculum refers to the areas of the cerebrum (telencephalon) or the frontal, temporal and parietal lobes that cover the lobus insularis. They are the seat of the motor speech centre.
Anatomy[Bearbeiten]
The various parts of the operculum border on the lateral sulcus. A distinction is made in a clockwise direction:
- Operculum orbitale: It lies inferior to the anterior ramus of the lateral sulcus.
- Operculum frontale: It lies between the anterior ramus and the ascending ramus of the lateral sulcus.
- Operculum parietale: It lies superior to the lateral sulcus and extends from its ascending ramus to the dorsal end of the sulcus.
- Operculum temporale: It lies inferior to the lateral sulcus.
The operculum is supplied by the M3 branch of the middle cerebral artery. Operculum parietale and operculum frontale are also drawn together to form the operculum frontoparietale.
