Nerves are like the body’s electrical wiring system, carrying messages between the brain and the rest of the body. They are made up of bundles of long, thin cells called neurons, which have the ability to transmit electrical signals. These signals travel through the nerves at a very high speed, allowing the body to respond quickly to stimuli and coordinate its movements.
There are two main types of nerves:
- Sensory nerves: These carry signals to your brain to help you touch, taste, smell, and see.
- Motor nerves: These carry signals to your muscles or glands to help you move and function
Nerves are a crucial part of the nervous system, which includes the brain and spinal cord. They help control everything from voluntary movements to involuntary functions like breathing and digestion
The nerves in human body is estimated to be more than 75 Kms if stretched out end to end.
The total length of the nerve fibers in the human brain is approximately 500,000 Kms
Where are your nerves located?
Many nerves start in your spinal cord and some even from your brain. They extend throughout your body, including in your:
- Arms, including your unlnar nerve, mdedian nerve radial nerve and axillary nerve.
- Chest and abdomen, including your vagus nerve and phrenic nerve.
- Face, including your facial nerve, trigminal nerve and optic nerve.
- Legs, including your sciatic nerve, fermoal nerve, tribal nerve, obturator nerve and sural nerve.
- Pelvis, including your prudenal nerve.
Conditions and Disorders
What conditions and disorders affect the nerves?
Some conditions affect how well your nerves send signals. If damage or injury interferes with nerve signals, you may develop a neurological condition.
Common conditions that affect the nerves include:
- Peripheral neauropathy: Damage to your peripheral nerves (nerves outside of your brain and spinal cord).
- Sciatica: Pain that affects the nerve roots in your lower back, or your sciatic nerve, the nerve that runs from your lower back down the backs of both legs
Nerves can get damaged in several ways, leading to a variety of symptoms and complications. Here are some common causes of nerve damage:
- Injury: Accidents, falls, or sports injuries can stretch, compress, crush, or cut nerves
- Medical Conditions: Diseases like diabetes, Guillain-Barre syndrome, and carpal tunnel syndrome can damage nerves
- Autoimmune Diseases: Conditions such as lupus, rheumatoid arthritis, and Sjogren’s syndrome can lead to nerve damage
- Infections: Certain infections, like Lyme disease and leprosy, can cause nerve damage
- Toxic Exposure: Exposure to toxic chemicals, including heavy metals and some medications, can harm nerves
- Nutritional Deficiencies: Lack of essential nutrients, particularly B vitamins, can lead to nerve damage
- Alcohol Consumption: Excessive alcohol intake can result in nerve damage over time
How can I keep my nerves healthy?
You can keep your nerves and entire nervous system healthier by adopting healthy habits, like:
- Avoid tobacco and smoking.
- Eat a nutritious diet full of whole grains, healthy fats, lean protein, fruits and vegetables.
- Limit Alcohol intake.
- Manage health conditions that can affect your nerves, such as diabetes.
- Reduce stress with healthy coping techniques such as meditation or excercise.
- Sleep at least seven to eight hours each night.
- Stay hydrated by drinking plenty of water and other fluids.
- exercising regularly.
