Precentral sulcus

The precentral sulcus appears in the central part of the cerebellar hemisphere (dorso-medial frontal lobe, superior frontal gyre) and is located between the upper part of the anterior callus and the lateral border of the central gyrus.

The groove of the precentral lobe is located from the upper edge of the foramen ovale and goes down to the body of the caudate nucleus. It separates the central part of the thalamus from the subcortical nuclei and is located on the border of the precentral convoluted tract and the posterior internal roll. The sulcus is the main location of Broca's area - a collection of nerve cells that are responsible for speech and control of facial expressions. This is also called

The precentral bone groove is an important structural feature of the human skeleton, has many functions and holds a special place in neurology. This groove is located on the lateral side of the middle part of the cranial vault, extending from the anterior to posterior part of the precentral part of the brain. The sulcus is called the precentral sulcus because it is located in front of the central lobes of the brain, which consist of gray matter. As we will see later, this groove has a significant impact on the functioning of the brain and nervous system as a whole.

The precentral bone is a fairly deep depression in the brain. This depression is surrounded by blood vessels and nerve fibers. Therefore, to ensure normal blood circulation and transmission of nerve impulses, the integrity of this groove is necessary. The state of the precentral bone determines the sufficient nutrition of the cerebral cortex and many other deep structures of the brain; it also affects the ability to understand certain speeches,
