Hand LENGTH & BREADTHHand FACTS> Adult hand is made up of:

> 27 bones> 37 skeletal muscles>20,000+ nerve receptors in the 10 fingertips

> A hand can:> Detect a raised dot as little as 3 microns high (human hair = 50-100 microns) > Sense .009" difference in height in the palm> Capable of 27 degrees of freedom

> Fingerprints provide:> A unique identifier that remains unchanged throughout the lifespan> A textural means of increasing traction and sensitivity at the fingertips

> Fingernails add:> An average of 2-3mm to female finger length> Structural support for the fleshy tips of the fingernails

> Handedness:> 8-10% of the population is left-handed> 50-60% of left-handers are highly ambidextrous

> Fine motor control and dexterity at the fingertips: > Is the last to develop during childhood> The first to succumb to age-related deterioration

> Aging hands:> 1 in 5 American adults have arthritis> Skin thins and loses elasticity; grip strength and tactile sensitivity are reduced

Finger SPAN> The diagram below describes average adult finger spans> Place your thumb lightly on the thumbprint and a finger on the corresponding line to learn how you measure up> Values shown are adult averages

1. Thumb - Index Finger (6.1") 2. Thumb - Middle Finger (7.2")3. Thumb - Ring Finger (7.4")4. Thumb - Pinky (7.6")

Finger WIDTH> The diagram below describes finger width at the distal interphalangeal joint> 95th percentile, adult male dimensions shown> Place your corresponding finger over the diagrams to see how you measure up

> The diagram below describes anthropometric ranges in hand length and width> Center the crease on the inside of your wrist on the below

> 5th - 95th percentile adult male

> 5th - 95th percentile adult female
