Polydactyly is a birth defect that results in extra fingers or toes. [2] The hands are more commonly involved than the feet. [2] Extra fingers may be painful, affect self-esteem, or result in clumsiness. [3] It is associated with at least 39 genetic mutations. [4] It may either present alone or with other defects. [2] Cases may run in families. [2]
Writing is a fine motor skill as it requires subtle motions of the hand and fingers. Motor skills are movements and actions of the bone structures. [1] Typically, they are categorised into two groups: gross motor skills and fine motor skills. Gross motor skills are involved in movement and coordination of the arms, legs, and other large body parts.
Fine motor skills are the coordination of small muscle movements which occur e.g., in the fingers, usually in coordination with the eyes. In application to motor skills of hands (and fingers) the term dexterity is commonly used. The term 'dexterity' is defined by Latash and Turrey (1996) as a 'harmony in movements' (p. 20).

The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen, the pubic region surrounding the genitals, the femoral region encompassing the thighs, the patellar region encompassing the front of the knee, the crural region encompassing the lower leg, between the knee and ankle,
The extremity of each arm, known as the hand, has five opposable digits known as fingers (made up of metacarpal and metatarsal bones for hands and feet respectively) and specializes in intrinsic fine motor skills for precise manipulation of objects. The human legs and their extremities — the feet — are specialized for bipedal locomotion.
When Smith has an attack, her fingers become white, then yellow and eventually blue. Her toes and ears do the same. If she tries to grab something with her hand, she can’t feel it.
