Final answer:
Motor functions in late adulthood often see a reduction in strength, changes in the nervous system, and alterations in skeletal structure, matching option b) Strength, nervous, skeletal structure.
Step-by-step explanation:
Motor functions in late adulthood typically involve a reduction in strength, changes in the nervous system, and alterations in skeletal structure. As such, the most accurate completion of the statement would be: Reduction in strength, changes in the nervous system, as well as from changes in skeletal structure, which corresponds to option b) Strength, nervous, skeletal structure.
During late adulthood, there is a notable decline in physical capacities, such as strength and reflex times. The nervous system experiences a slowdown in reaction times, and changes in the skeletal structure can include conditions such as osteoporosis, which affects bone density and strength. Additionally, muscle mass diminishes, a condition known as sarcopenia, which can affect balance, posture, and overall mobility.
