Spiral Furrow Internal

The internal spiral groove (sulcus spiralis internus) is an anatomical structure that is located inside the spinal cord. It is part of the spinal canal and connects the spinal cord to the spinal canal.

The internal spiral groove has the shape of a spiral and runs through the entire spinal canal. It consists of two layers of tissue: an outer layer of dura mater and an inner layer of pia mater.

The functions of the internal spiral groove include the transmission of nerve impulses from the spinal cord to the peripheral nerves and back. In addition, it plays an important role in maintaining the structure of the spinal canal, ensuring its strength and stability.

If the internal spiral sulcus is damaged, it can lead to disruption of the transmission of nerve impulses and dysfunction of the spinal cord, which can lead to serious consequences. In this regard, it is important to monitor the condition of the internal spiral groove and, if necessary, take preventive measures to strengthen and protect it.

Conclusion:

Thus, the internal spiral groove is an important anatomical structure that plays a key role in the transmission of nerve impulses between the spinal cord and peripheral nerves. If the internal spiral groove is damaged, serious consequences can occur, so it is important to monitor its condition and take preventive measures to protect and strengthen it.

Internal spiral groove

Spiral groove (lat. sulcus spinalis internus; lat. externus - external and lat. spire - spiral; syn.: peripheral groove) is a depression in the bone substance of the skull, shaped like a spiral, located medial to the midline of the brain and corresponding to the medial circumference of the brain along its entire length. The internal spiral groove connects the posterior part of the temporal fossa with the parietal bone. There is a two-way mutual arrangement of the grooves in the form of casting paste. It is described by the crural medullary groove in the interpubic region. Its circumference has been expanded, forming a clear spiral groove on the back wall that divides the brain matter into layers. The size of the groove is about 2.0 mm. The width of the groove in adults can be about 7.8 ± 1.6 mm, and the length can reach 43.5 ± 8.1 mm. The veins that form grooves in crows are directed downward and laterally. These veins pass upward through the greater occipito-parietal cinus and reach the hypothalamus through the optic chiasm. The layered groove is closely related to the paraphrenic tissue of the deep groove of the brain
