Technical Tuesday Arrector Pili
As strange as it may seem, each finger
has only one “muscle”: the arrector pili. To be completely technical, fingers
actually don’t contain muscles at all - the muscles that do move the fingers
are in the palm of the hand and the forearm. The arrector pili are actually bands
of microscopic muscle tissue that connect the hair follicles to the dermis (skin).
When the arrector pili are contracted,
the hair stands on end, often resulting in the sensation we call “goose bumps”.
In the area of bizarre facts about
fingers: Lui Hua, of China is the man
who has the largest hand in the world. His index finger is almost twelve inches
long, and his left thumb is more than ten inches. This is caused by a condition
called “macrodactyly” – which means – no surprise here - big fingers.

muscle.”

Quote of the Day:
“If, while
at the piano, you attempt to form little melodies, that is very well; but if
they come into your mind of themselves, when you are not practicing, you may be
still more pleased; for the internal organ of music is then roused in you. The
fingers must do what the head desires; not the contrary.”
― Robert Schumann
