Notch (Valleculd)

Notch (Valleculd) - a groove or depression in any organ or other part of the body. For example, a notch on the inferior surface of the cerebellum separates its two hemispheres.

Notches are formed as a result of folds or partitions between different structures of the organ. They play an important role, delimiting functionally different areas and helping the body perform its functions more efficiently.

The most famous notches are found in the brain. For example, the interhemispheric fissure separates the left and right parts of the cerebral hemispheres. There are also indentations inside the ventricles of the brain that increase the surface area for the circulation of cerebrospinal fluid.

Notches and grooves play an important role in anatomy, allowing the separation of structures and increasing the efficiency of their functioning. Their study provides an understanding of the structure and functioning of organs and systems of the body.

A notch, or vallecula, is a groove or depression located in various organs and tissues of the body. They can be found in various parts of the body such as the brain, liver, kidneys, lungs and heart.

One of the most well-known notches is the notch in the inferior surface of the cerebellum, which separates the two hemispheres of the cerebellum. This notch is called “fissura cerebelli” and is about 3 mm long. It plays an important role in motor coordination and balance.

Indentations may also be found in other organs, such as the liver. The liver has indentations called “lobules” that form the lobules of the liver. These grooves help the liver perform its function of filtering blood and producing bile.

In addition, indentations may be found in other parts of the body, including the lungs, kidneys, and heart. The indentations in the lungs are called “fissures”, and in the kidneys - “lobuli”. These notches are also important for the functioning of the organs.

Overall, the notches play an important role in the body by helping organs function more efficiently and providing structure and shape.

Brain recesses, what are they? One of the largest complexes of pathways in the human body is the vascular bridge. It is located in the longitudinal direction. This complex covers the brain stem, which connects the hemispheres to each other. Between them is precisely the recess that will be discussed. If you don't know exactly what it's called, this designation can be confusing.

- **Bed of the trigeminal nerve** Quite widely developed on the upper part of the buccal fossa in the thickness of the towering processes of the trigeminal and glossopharyngeal nerves, as well as in the midbrain in the region of the peduncles of the greater gyrus. This area has a scientific name - vallecululdum. There are many ganglion cells of the first and second branches of the trigeminal nerve. In addition, multiple fibers of the inferior salivary nerve are located here. In the middle sections of the cheekbastion the capsule is partially closed. - *Valleculum* In the thickness of the temporal lobe, it is mainly located in the interpeduncular fossa between the olivial and cavernous foramen. An oblong elevation formed by the arched lower surface of the temporal fossa. On the lateral wall of the recess there are the epiphysis (pineal body) and the geniculate body, on the medial wall there is the optic nerve sheath and the upper fields of the retina. - The performance begins with a narrow upper neck, imperceptibly turning into a wide lower neck. That is, it has the shape of an isosceles triangle. Its boundaries are the transverse and connective tissue branches of the ligaments and the vascular sinus, which protrudes into the thickness of the cleft ligament. The temporobuccal tract passes into it, rotating there up and down, like a whip. In some individuals, instead of a wide canal, the notch has a narrow, deep groove that runs parallel to the promontory of the sphenoid bone. And sometimes along its edge there are no fusions of the corresponding fibers and ligaments at all. This creates the deepest hole in the skull. Sometimes the edges of the gap have clear outlines, but in some cases the edge of the canal may be unclear due to the sharp growth of trabeculae. The notch is always shorter than the process of the vallecula based on the same characteristics, that is, in the same person it may not be in contact with the process and, conversely, on the skulls of different individuals they may be similar in shape.
