The prefix pseudo (from Greek ψευδής "lying, false") is used to mark something as false, fraudulent, or pretending to be something it is not. (Wikipedia)
“No animal has hands as well developed as those of man. The sculptor Auguste Rodin considered the hand to be the proof of the “divine creative force”. He paid homage to this idea in his sculpture “The Cathedral”, representing two hands facing each other, creating the shape of a vaulted arch. The hand is the organ devoted to prehension and touch. Touch can be sensed all over the body, but the real tact is concentrated in the hand and fingers, which move over an object to determine its volume, temperature, and nature. The fingers of man have epidermal and dermal folds which we call the fingerprint. These fingerprints are unique to each individual, and allow an increase in the surface area of the skin at the ends of the fingers greatly raising the number of sensory receptors present. The hand is also an organ which allows us to communicate.
The sensitivity of an organ is defined by the sensitivity threshold to a mechanical stimulation (entry of a point to a depth of 6 m) and the spatial discrimination threshold (separation measured with dividers). Lowest thresholds occur at the tip of the tongue and on the fingertips (1-3 mm). The fingers have a very high density of touch receptors, which has led to an over-representation of the fingers in the somato-sensory cortex.”
