Median Sulcus

The median (middle, lateral, central, etc.) sulcus is one of the superficial anatomical elements of the middle cerebral fossa, located between the cerebral hemispheres and uniting them using neural connections.

The median groove connects the ventral surface of the hemispheres, dividing them into medial and lateral surfaces, and forms their lower border. The groove is crossed by the median eminence at the position of the 5 lobes and Schlemm's groove, separating from the subterminal groove. In the temporal lobe, it borders on the commissural grooves located along the end of the corpus callosum on the lower surface. At the limbic lobe, the groove becomes the posterior border of the chewing groove, which differs in hygrotype.

The general direction of the groove is anterior-posterior, fronto-occipital. In the lateral direction it changes from occipitotemporal to temporotransverse. The thickness of the grooves is small - 0.2-0.3 cm, the width reaches 1.5 cm. According to some authors, the depth of the grooves is 0.7 cm, which can be observed in adults, but is not typical for the fetus.

In men, the groove is located more outside the central part of the cerebral hemispheres than in women. Otslo

The median groove (lat. sulcus medians - semi-groove, embryology) runs in the middle of the skull inside the nasal septum. This is where the nasal bone attaches. In the thickness of the lateral plate of the ethmoid bone (in the bone plate) there is an opening through which the inferior nasal meatus approaches the central nasal groove. On copper
