Answer:  The major function of the human hand is to manipulate objects to accomplish a goal.

1)The ability of a human hand to assure a myriad of position and to apply only the precise amount of pressure necessary to hold an object is due to: the mobility and stability supplied by the skeleton: the power of the muscle; the remarkable degree of sensory feedback from the nerves.

2)The sensory feedback is used to asses the shape, size, texture and weight of the object. The feedback used in both grasping and lifting of an object is dependent on the brain interpreting correctly, what is seen on the hand responding appropriately.[1]

3)Hand function has great significance for occupational performance. The greater the difficulties with hand function, the greater the impairment in skills that allow for independence and participation in academic and social activities
