Q. Elucidate the meaning of motor development.
Ans. Motor development refers to the development of a child’s
bones, muslces and ability to move around and manipulate
his/her environment. In simple words, motor development
means the development of movement various motor abilities

running, climbing, catching or holding, jumping skipping or
throw etc. Motor development can be divided into two types
i.e,. gross motor development and fine motor development.


Q. Mention types of motor development in child new.
Ans. 1. Gross motor development: It involves the development
of large muscles in the child’s body such as sitting, walking,
running, climbing etc.
2. Fine motor development. It involves the small muscles of
the body specially in the small movement of the fingers
and hands. For example, holding of javelin, discus, pole,

motor development in children.

a child follows the same pattern as of their parents. These
factors are related to body weight, size and strength.
2. Envirnmental Factrs: Envirnmental factors such as
physical and social factors are likely to effect the motor
development. Encouragement, love and security help the
child to take risk to explor fearlessy which leads to better
motor development. Those children, who are not encouraged or motivated towards motor activities have slow rate of motor development.
3. Nutrition: Nutritive food promoter good motor development.
If they get nutritive food, they get stronger & their
development is good. If they dont get proper nutrition they
are found to be less energetic & their motor development
taken place slowly.
4. Physical Acitivities: Those children, who do not perform
or practise physical activities regularly their motor
development becomes slow. However, the physical activities
must be according to the capabilities of children.
5. Opportunities: Children who get more opportunites to
perform more activities, motor development is better in
them. Opportunities to play give a better chance of
developing sensory motor activities. If porper opportunities
are not given to children their motor development cannot
take place in those childern properly.
6. Disability and Disease: Disability and disease affects
motor development. It reduces perfection in motor skills
whereas healthy perosn gain faster motor development.
7. Body Weight: Overweight and obese children have less
motor development whereas healthy child has more skill
perfection.
8. Mental Ability: Motor development depends upon mental
level, thus small children have less perfectionn.
9. Regular Practice: With regular practice motor
development and perfection is gained.
10.Immuniztion. If mother and child both are immunized at a proper time it leads to good sensory motor development.
