Tubercle of the Subtle Core

Tubercle of the Grain Nucleus: An Anatomical Review

The Tuberculum Nuclei Gracilis, PNA, is one of the structures in the human central nervous system. This structure is located at the back of the brain and plays an important role in processing tactile information.

Anatomically, the tubercle of the Thin Nucleus is located on the posterior surface of the cerebellum, in the projection of the lateral lobes of the medulla oblongata. It is shaped like a small protrusion and is connected to another brain structure, the tubercle of Charpy. Together they form the core of the deep posterior column.

Functionally, the tubercle of the Subtle Nucleus plays an important role in processing information about tactile sensations and the position of the body in space. It receives nerve impulses from skin receptors located in various parts of the body and processes this information before sending it to the brain for further interpretation.

In addition, the tubercle of the Subtle Nucleus is also involved in regulating muscle tone and maintaining balance. These functions are carried out through the interaction of the tubercle of the Subtle Nucleus with other brain structures, such as the cerebellum and midbrain.

Although the eminence of the Grain Nucleus is a relatively small structure in the brain, its role in processing tactile information and regulating muscle tone is critical to the normal functioning of the body. Disturbances in the functioning of the tubercle of the Subtle Nucleus can lead to disturbances in balance, coordination of movements and processing of tactile information.

In conclusion, the Tubercle of the Subtle Nucleus is an important structure in the human central nervous system. It plays a key role in processing information about tactile sensations and body position in space, as well as in regulating muscle tone and maintaining balance. If the functioning of the tubercle of the Subtle Nucleus is disrupted, various neurological disorders can occur, so its study is an important area in brain science.

The tubercular nucleus is part of the dura mater, separating it from the pia mater. Together, the tubercle of a sharp edge forms the bottom of the fourth ventricle and the posterior inferior surface of the cerebellum. A depressed tubercle is not formed. On the outside, the tubercle is covered by a layer of the cerebellar mucosa, and on the inside by the dura mater. The anterior surface of the tubercle grows to the base of the cerebellar peduncle and to the pyramids of the temporal bones, with the exception of their apex, the posterior surface descends back to the nasal surface of the cerebellum and caudal fold. At its border with the pia mater there are narrow venous channels (up to ten), clogged from the outside by weak elastic sphincters.

At the base of the tubercle the nerve root of the posterior vagus nerve passes to the nucleus colliculus inferius, from the tubercle the cavities for
