Thumbs Up to the Thumb

"The fingers must be educated, the thumb is born knowing" - Marc Chagall

One of the five fingers of a hand is designated as the thumb and the rest of the fingers are named as per size, position and the functions they perform.

The thumb is the shortest and the stoutest than the other four fingers. If we hang the entire upper extremity downwards and position the palm frontwards the thumb lies away from the midline (called lateral) and this position is universal and referred to as the anatomical position which is used when we talk about other structures in relation to the thumb. This anatomical position of the thumb is also known as the radial side since it is in line with the radius bone of the forearm.

The thumb holds an important place amongst all the organs in the human body including the vital organs like heart, lungs and the brain in relation to the important functions it performs.

Without a thumb or a non-functioning thumb one cannot perform important functions like: holding a pen to write, buttoning or unbuttoning a garment, holding a spoon to eat or even picking up a marshal of food, combing hair, counting currency, using a key to start the car or open the lock on the door. No function can be performed that needs a direct or indirect co-ordination of the thumb in many intricate actions with just the other four fingers.

The thumb is a very important feature of the hand in that, without it the rest of the hand will have no driving force or will power to perform any action.

Anatomy: Each finger has three small bones called phalanges except the thumb, which has only two phalanxes. When the hand is in its anatomical position the lower phalanx is called the distal and the upper one as proximal phalanx.

An average thumb will reach the middle of the proximal phalanx of the adjoining index finger. If its length were measured it would equal the length of the little finger.

The development of the human thumb with an ability to oppose all four fingers is what has allowed a human being to use the hands in a way that no other animal can. This unique power in a human gives the power to exert some influence over the surrounding environment. Therefore, a strong powerful thumb gives its owner a strong will power and determination with an ability to exert some kind of a unique force to gain a mastery of one’s own life with an ability to perform any type of task with his/her hands.

The most common condition that can affect a thumb is an injury resulting either in loss of a part or whole of the thumb or in paralysis of the muscles of the thumb making it nonfunctional though the thumb does exist. In some unfortunate persons there may be congenital absence of the thumb(s).

The thumb may be affected with infections leading to temporary loss of functions of the thumb till infection subsides and functions are restored. In some cases there may be an additional finger usually attached to the thumb in which case the functions are to some extent sluggish and not on par with those when there is no deformity.

The thumb has rich blood and nerve supply. If any vessel is damaged it may lead to indirect loss of functions depending on the muscles which the artery supplies or the nerve innervating the muscle.

Some excerpts based on researched statistics on the astrological importance of the thumb puts a lay person in disbelief, and may change his mind about astrology.

  • The top phalanx of the thumb represents a person’s will power and determination.
  • If the top phalanx is long, at least equal the length to the other phalanx below it, or longer than, the person will have stronger will power with a determination to push himself forward. He will be tenacious and clear minded with an uncanny ability to give orders and make decisions.
  •  The mount of Venus, surrounding the ball of the thumb may be considered the third phalanx, representing the amount of love within the character.
  • A very short top phalanx reveals the absence of these qualities with a tendency to be careless and indifferent.
  • The second phalanx of the thumb represents logic and reasoning ability. If it is long there will be plenty of logic behind the actions.
  • If the second phalanx is short, the owner will lack reasoning capacity and often makes quick and instinctive decisions on the spur of a moment.
  • The best combination would be when the top and the second phalanxes of the thumb are equal in length, which would mean that the will power and logic are in balance. However, we don’t often find such a combination and in majority of cases either one of the two phalanxes will be short or longer than the other. 

A person with a short top phalanx will be ruled by sentiment and always prefers to be led and guided by others without any individuality.
