Nerves of the kidney

This is in response to an enquiry: “How long does it take for a nerve to regenerate in the kidney?”

The nerves of the kidney, like the nerves of internal organs and their functions such as breathing, heart beat, belong to the autonomic nervous system. Unless one is an extremely accomplished master of meditation, one is unable to “control” the autonomic nervous system and the autonomic functions of breathing, heart beat, digestion, blood pressure, pulse, etc.

The necessity to regenerate a nerve in the kidney may exist if one undergoes a kidney transplant. Besides the usual organ rejection problems, blood type matching would usually be done beforehand. Therefore, blood type mismatch is usually not a problem during or after kidney transplant. In organ transplants, rejection is usually the action of the immune system that is fighting off foreign organs within the body after transplantation.

If a nerve to the kidney is severed, dead, dying, that means that a part of the autonomic nervous system is not functioning, i.e., a part of the autonomic nervous system is dead. Usually, only a corpse has no functioning autonomic nervous system. A person in a coma and a vegetative state still has a healthy functioning autonomic nervous system. There have been cases of coma patients becoming pregnant after being sexually violated.

Fibrillation and defibrillation are very good illustrations of a “revival” of autonomic nerve function. Fibrillation is “very rapid irregular contractions of the muscle fibers of the heart resulting in a lack of synchronism between heartbeat and pulse.” [Merriam-Webster’s Medical Dictionary]

The broader meaning of fibrillation is “a muscular twitching involving individual muscle fibers acting without coordination.” [Ibid]

Defibrillation is the “restoration of the rhythm of a fibrillating heart” using a defibrillator. [Ibid]

Fibrillation is thus a sudden dysfunctioning of the regulatory function of the autonomic nerves to the heart that results in an incoordinated muscular twitching of individual muscle fibers. The defibrillator “revives” the coordinated rhythm of the misbehaving muscle fibers. In emergency medicine, fibrillation of the heart is indicated by a lack of pulse and heartbeat rhythm.
