Nerves
The function of the nerves is to send signals of sensation to the brain. There are three main types of nerves in the body: motor, automatic, and sensory. It is through the sensory nerves that the information gathered by the eyes, skin, ears, nose, and tongue are directed to the brain for processing and reaction. A person who puts a hand on a hot pot has the sensory nerves in his hand send a signal to the brain where in milliseconds, a response to remove the hand is sent back through the motor nerves and the person jerks back his palm before it burns. The automatic nerves regulate a person’s breathing, heart rate, digestion, and other unconscious bodily functions.
The nerves can be thought of as the body’s electrical system. Each nerve is composed of a bundle of axons which act as cables. Nerves act to connect the peripheral nervous system (PNS) to the central nervous system (CNS). The CNS is composed solely of the brain and spinal chord whereas the is PNS is the nerves outside of this.
Damage to the nerves can occur and does with frequency in many jobs. One of the most common forms of damage to the nerves is a “pinched nerve”. This can lead to a feeling of pins and needles in the area below the nerve. Feet and hands falling asleep are daily occurrences for those who sit or stand in one place for a long time. Pinched nerves are usually not serious and can be treated with rest under a physician’s guidance. More severe damage to the nerves can result from chronic diseases such as diabetes or physical trauma such as frostbite or bodily harm. Any extended time of a sensation of numbness should be discussed with a physician for prompt treatment to prevent permanent damage. So, related to this, if you want to keep your nerves calm get your life insurance as soon as possible.
