The left-hand little finger, aka pinky, is the smallest and weakest of our fingers. It is shorter than other fingers.
They are all pretty much equal. The thumb is often thought of being the strongest because it is opposable and we think it's flexor is strong but the flexors in the other fingers are just as strong. The thumb without the other fingers to oppose it is, well, weak and pretty much useless.
It is the weakest of the fingers on the hand, as it shares a flexor muscle with the middle and little fingers.
It is located between the thumb and the middle finger. It is usually the most dextrous and sensitive digit of the hand, though not the longest. It is shorter than the middle finger, and may be shorter or longer than the ring finger (see digit ratio).
The little finger actually moves easier than the middle and ring fingers. That's because it also has independent muscles for some movements. However, it also relies on muscles shared with the other three fingers for some actions, thereby limiting your control.
Conclusions: The middle finger was the most important contributor to grip strength. The next most important was the combination of the ring and little fingers.
Smaller fingers may create a more precise sense of touch, according to a study published this week in the Journal of Neuroscience.
Strength of the grip and strength of the fingers are highly correlated. The contribution of the index finger is about 25% of the total force, the middle finger 35%, the ring finger 25% and 14% of the force is contributed by the pinky.
Results: The index and middle fingers were the fastest fingers for both hands, and little fingers the slowest. All dominant-hand fingers, except little finger, had higher tapping rates than the fastest finger of the nondominant hand.
Your thumb is thicker than all the other fingers on your hand because it has to oppose all 4 of the other fingers - meaning that if you hold an object, you have 4 fingers on one side of it to maintain the grip while the other side there is only the thumb to provide an equal amount of force.
According to the assistant chief of hand surgery at the NYU Hospital for Joint Diseases, the little finger does a disproportionate amount of gripping, while all the other guys are its helpers: The other three digits—the index, the thumb and the middle finger—they fine tune where the tool goes.
The index finger, (also referred to as forefinger, pointer finger, trigger finger, digitus secundus, digitus II, and many other terms), is the first finger and the second digit of a human hand.
The pinkie holds as much as 50% of your hand strength. The pinkie along with the ring finger forms the power bottom of your hand while the thumb, index finger, and middle finger provide dexterity. In fact, losing your little finger and ring finger can reduce your grip strength by 67%.
The fourth finger of the left hand, believed to possess a vein that runs securely to the heart, has traditionally been ringed. This Vein of Love, or more amorously called the Vena Amoris, 1 originated in ancient Egypt, where it was first described by Macrobius in 395–423 AD.
BACKGROUND: Most of the people cannot flex their minimus, without the rind finger, along with it, this occurs because of human anatomy. The muscle connected to the tendons for those fingers are close or connected to the same. The tendons and bones are usually connected for last two fingers.
The most common hand fracture is a fracture of the fifth metacarpal — the bone in the hand that supports the little finger. This is commonly called a “boxer's fracture” and involves the "neck” of the bone, next to the knuckle joint.
“The finger snap occurs in only seven milliseconds, more than twenty times faster than the blink of an eye, which takes more than 150 milliseconds.”
Overall, the thumbs presented higher temperatures than the other fingers (Figure 2).
It is a common condition that often runs in families. The extra fingers are usually small and abnormally developed. Polydactyly is one of the most common congenital (present at birth) hand abnormalities. About one out of every 500 to 1,000 babies are born with the condition, usually with only one hand affected.
Etymology. The word "pinkie" is derived from the Dutch word pink, meaning "little finger". The earliest recorded use of the term "pinkie" is from Scotland in 1808.
So what would you lose if you didn't have one? “You'd lose 50 percent of your hand strength, easily,” said Laurie Rogers, an occupational therapist who is a certified hand therapist at National Rehabilitation Hospital in Washington.
Doctor Answer is medically reviewed by SecondMedic medical review team. The part of the body that has the most nerve endings is probably the fingertips. Each fingertip contains approximately 3,000 nerve endings called Meissner's corpuscles, which are designed to detect light touch and vibration.
The receptors in our skin are not distributed in a uniform way around our bodies. Some places, such as our fingers and lips, have more touch receptors than other parts of our body, such as our backs. That is one reason why we are more sensitive to touch on our fingers and face than on our backs.
The forehead and fingertips are the most sensitive parts to pain, according to the first map created by scientists of how the ability to feel pain varies across the human body.
