Nerves are the transmission systems that enable the messages coming from the brain to carry signals to various parts of the human body and deliver the warnings from various parts of the body to the brain. The nerves contain millions of fibers, and these fibers are arranged in groups in the form of cables surrounded by protective sheaths. This system, which carries the message in the case of cables, is also surrounded by a protective insulating material.
The nerves are two types: motor nerves that carry the conduction from the brain to the muscles and control the movements;
Nerves can be damaged by stress, pressure and shear. In stress and pressure injuries, the structure of the protective layer around the nerve does not deteriorate, but due to the damage to the fibers, the conduction system deteriorates and the nerve becomes inoperable. If cut, both nerve fibers and the surrounding protective layer are damaged. After injury, the muscles cannot transmit messages from the brain and perform functions, or sensory herpes from various parts of the body cannot be transmitted to the brain.
Hand and nerve injuries need to be repaired with microsurgical technique in expert hands.
