Tingling, also known as paresthesia, is the prickling sensation usually felt in the hands, arms, legs, or feet. Tingling hands in children is usually harmless and may be the result of a number of different causes.

In modern life, we are often bombarded with information and sensory input, triggering the “fight-or-flight” response. The hypothalamus, in turn, causes the adrenal glands to release stress hormones such as adrenaline and cortisol.

Calcium is an essential mineral present in all of your body's cells, mostly in your bones and teeth, but in soft tissues as well. You can acquire calcium through foods and nutritional supplements, and it has a variety of effects on your body, including effects on your nervous system.

Involuntary processes in your body such as heart rate and blood pressure are controlled by a segment of your nervous system called the autonomic nervous system. One part of the autonomic system, called the sympathetic nervous system, controls your basic “fight-or-flight” responses.

The femoral nerve is one of the largest nerves in the leg. The nerve and its branches supply sensation to the upper thigh and control the quadriceps muscle, which is responsible for straightening the knee. Femoral nerve pinching, or impingement, can cause various symptoms.

Finger numbness can significantly affect your ability to perform daily tasks. Normal sensation allows you to type without looking at your fingers, and prevents you from burning yourself or touching a sharp object.

The nervous system consists of three main nerve types. Sensory nerves supply humans with the ability to see, hear, smell, taste and feel. Motor nerves enable the brain to command the muscles of the body. Autonomic nerves regulate the function of the internal organs.

When doctors check reflexes, they don’t always get a normal response. Clonus, a type of hyperactive reflex, is a rhythmic response to reflex testing. Instead of just one movement, a series of repetitive reflex movements are observed.

The word "muscle" comes from the Latin for "little mouse." In its overview of how the nervous system works and acts upon other bodily systems, the University of Michigan's Medical School emphasizes that all aspects are always fully coordinated and interrelated. For this reason, subdivisions into "central," "

The central nervous system includes the brain, brain stem and spinal cord and is the main infrastructure for electrical communication in the body. A variety of nutrients are required for normal neuronal development and healthy functioning.
