Give the function for the structure labeled “C” on the model above.

Collectively, these structures are known as ?

After age 50 years, both the number of and diameter of muscle fibers decrease in the average older adult.

The heart follows the sigmoid pattern of whole-body growth, and the growth of the blood vessels surrounding the heart is proportional to that of the heart; therefore, the size of the heart is not a limiting factor for exercise in children.

The asymmetries in hand use demonstrated during infancy predict which hand will be dominant in adulthood.

Which is an example of an extrinsic factor that can affect growth?

The asymmetries in hand use demonstrated during infancy predict which hand will be dominant in adulthood.

In changing from a throw for distance to a throw for accuracy, the most likely change observed would be a transition to lower steps in the developmental sequences.
