The fingertip is the end of the finger on the human hand. The Latin term for the fingers of our hand is Digitus manus. If we look at our hand, we see 5 different fingers: thumb, index finger, middle finger, ring finger and the little finger.
Despite the fact that all fingers are different, their structure or their anatomy basically show parallels, one speaks of one same basic structure: The Fingertip can also be used as foremost phalanx and on it is the Fingernail (lat. Unguis). This consists of keratin, a water-insoluble fiber protein and primarily fulfills one Protective function of the fingertip. In addition, this is only present in higher primates, since the nail is evolutionarily derived from the so-called epidermis, i.e. the uppermost part of our skin. This is located under the keratinized fingernail Nail bed, which consists of connective tissue and is firmly attached to the periosteum. In the area of the nail one can see the so-called Nail moon, a white crescent-shaped mark.

In addition to the nail, the Fingertip Another important meaning, for example it appears frequently in criminology: Every fingertip has a characteristic patternwhich is unique and to Identification of an individual serves that fingerprint. This contains many Touch and pressure receptors, about 700 pieces and thus fulfills an important function for the Feeling an object. Several arteries and veins can also be found on the finger, as well as fatty tissue. The arteries that are particularly important here are Terminal branches of the radial artery and the Ulnar artery.
To move the finger we need Musculature, which attaches to the respective finger bone and for the Fine motor skills (e.g. writing and feeling) plays a decisive role. The Fingertip joint is a Hinge joint, which is a diffraction (Flexion) and a stretch (Extension) allows. There is also a Tape apparatus attached to the Stabilization of the finger joint serves. This consists of two side ligaments and two additional ligaments on the back of the hand and fingers. There are also tendons that are secured by so-called rings and cruciate ligaments. An analogy to the finger joint is the toe joint, which anatomically shows many similarities.

In the event of entrapment or injuries in which a nerve is damaged, this manifests itself in the symptoms of numbness on a corresponding skin area. One speaks here of so-called sensitivity disorders. The nerve that is most frequently disturbed here is the ulnar nerve, which runs on our "funny bones", with which most readers have probably already made acquaintance.
Another cause of numb fingers are polyneuropathies, i.e. other special diseases of our nervous system, which may be caused by an unhealthy lifestyle (overweight, excessive alcohol consumption). In addition, an anatomical tightness can occur, which can be summarized under the term carpal tunnel syndrome.
If numbness occurs in the fingertip, one should not hesitate to consult a neurologist who will physically examine the conduction velocity of the affected nerve, which is usually reduced. In most cases this can be remedied surgically. In a few cases, vitamin replacement therapy can also be successful.

In addition, a Anemia, a magnesium deficiency or an excess of potassium or a disc prolapse also trigger a tingling sensation in the fingertip.
Since the list of possible causes for a tingling sensation in the front finger is very long, it is all the more important see a professional. A detailed examination is necessary here, which can only be carried out by a qualified doctor.

You can go with up to 20 ° restriction expect when there are complicated fractures, poor primary care, and advanced age of the patient.
