The spine protects a tiny spinal cord that weighs only 35 grams.
Without him, we would lose the ability to move and move our limbs.

2025: World's first full spinal cord injury recovery technology developed - it combines 3D printing, stem cells and lab-grown tissue
University of Minnesota scientists have created a groundbreaking technology to treat spinal cord injuries that combines 3D printing, stem cells and artificially grown tissue for the first time to fully repair damaged nerve structures. The technique successfully demonstrated the ability to restore function after complete spinal cord rupture in laboratory animal experiments. The results of the study are published in the journal Advanced Healthcare Materials in August 2025. Read more here.

2020: Spinal cord disorders lead to loss of body hair
A fracture or other serious disorders in the spine can affect the state of hair growth.
For 2020, scientists still cannot thoroughly explain how a violation of the spinal cord affects the disappearance of body hair.

2025: How the spinal cord participates in sex. Scientific explanation
In late September 2025, Portuguese specialists from the Champalimaud Foundation released the results of a study suggesting that the spinal cord plays a more important role in male sexual behavior than previously thought. The findings, according to the authors of the work, could lead to a rethink of the ejaculation management mechanism.
For a long time, it was believed that the brain controls the sexual behavior of men, including agitation and sexual intercourse, while the spinal cord is responsible only for the final stage of the process - ejaculation. However, new research indicates that spinal chains are involved in shaping the entire sequence of sexual activities.
Scientists have identified a group of Gal + spinal neurons expressing the molecule galanin (Gal), which plays a key role in ejaculation. It turned out that these neurons are directly related to the motor neurons that control the bulbous-spongy muscle, which, in turn, is responsible for the release of sperm. Moreover, Gal + neurons receive signals from the genitals, and also communicate with other zones involved in erection.
Thus, the researchers conclude, Gal + neurons collect sensory information, process various signals and initiate motor activity, which ends with ejaculation. At the same time, the state of the body is assessed: after recent ejaculation, repeated stimulation does not give the same effect.
 | The spinal cord is not just a passive relay system executing brain commands. It [the spinal cord] integrates sensory signals, responds to arousal and adjusts actions depending on the internal state of the body, says Susana Lima, senior author of the study.[1] |  |
