index finger, pointer finger, or forefinger. middle finger or long finger, ring finger. little finger, pinky finger, or small finger.

In most cases, trigger finger is a nuisance rather than a serious condition. However, if it is not treated, the affected finger or thumb may become permanently stuck in a bent position or, less commonly, in a straightened position. This can make carrying out everyday tasks difficult.

The quickest and most effective treatment is a local cortisone injection into the tendon sheath around the affected tendon. Most patients will respond well to the steroid injection (corticosteroid injection such as kenalog, depomedrol, and others). Trigger finger can recur after a period of normal function.

Noun. wenis (plural wenises) (slang) The skin on the outside of the elbow.

five digits

The little finger, or pinky finger, also known as the fifth digit, or pinkie, is the most ulnar and smallest finger of the human hand, and next to the ring finger.

Ask an evolutionary biologist, however, and you’re likely to get a much simpler answer: We have 10 fingers and 10 toes because, somewhere in our species’ past Darwinian wanderings, those numbers gave us an evolutionary advantage. Had events tumbled differently, we might have eight fingers and twelve toes.

A thumb is a digit, but not technically a finger. Many people don’t make the distinction between thumbs and other digits.

fifth finger

During manual activities, fingers are typically used to push, pull, and manipulate objects. The finger force is demonstrated to vary in a range of 30 to 110 N, respectively, from the little finger to the thumb capable of exerting the maximum force [12] .

According to a study done by Virginia Polytechnic, it appears that the average ‘poke’ force is measured in newtons with the average being roughly 47N. This can be converted into lbs which yields the result of 10.36 lbs.

General guidelines suggest that hand forces should not exceed 45 Newton. On the other hand, its possible to handle a force of 4kg for 10s, 2kg for 1 min and one third of maximum force for 4 min.” These information can be useful while designing machines which is having human interactions, especially hand interactions.

Most buttons requireless than 1 pound of force, but some of the ones that are attached to a mechanical relay, including microwave door buttons, may require two or even 2 1/2 pounds.

According to a NASA report an average male can exert around 90 kg (200 pounds) or 1000 Newtons of force in a static push.

Types of Forces

Another study at the University of Michigan determined that the overall mean peak reaction force during a typing task is 2.54 Newtons (263.1 grams), which is 5.4 times the minimum key actuation make-force of . 47 Newtons (47.6 grams) (4).

No significant differences were found in typing productivity between keyboards, but there were differences in the applied typing forces across keyboards. Compared to the shorter travel (2.0 and 2.5 mm) keyboards, the applied typing forces and keystroke durations were highest with the longest travel (4.0 mm) keyboard.
