Medical Term of the Week: Sulcus centralis

The sulcus centralis, also known as the central sulcus, is a significant structure in the human brain that plays an important role in the separation and function of the brain lobes.

Etymology

The term "sulcus" comes from Latin and means "furrow" or "groove". "Centralis" refers to the central location of this structure in the brain. This designation emphasizes the central role of the sulcus centralis in the anatomical organization of the brain.

Anatomical Relevance

The sulcus centralis runs across the surface of the brain and separates the frontal lobe from the parietal lobe. It is one of the most prominent sulci in the human brain and plays a crucial role in the organization of motor and sensory functions. The precentral gyrus, located directly in front of the central sulcus, is responsible for the control of voluntary movements.

Clinical Significance

In clinical practice, the central sulcus is an important landmark in neurosurgical procedures. Changes or anomalies in this area can indicate neurological diseases, such as strokes or tumors. Precise knowledge of the location of the central sulcus is crucial for the planning and execution of brain surgery.

Did you know?

The central sulcus is present not only in humans but also in many other mammals. In the evolutionary development of the brain, its structure has proven to be extremely efficient in enabling the complex processing of sensory and motor information.
