A person riding a bicycle wants to move the bicycle forward. She moves

Question

her legs up and down on the bicycle's pedals. Then the rider wants to stop the bicycle. She stops pedaling and the bicycle slows. She takes one of her feet off a pedal and puts her foot on the ground to stop the bicycle and stay upright.
Which of these best identifies a pathway of systems in the rider's body, as described in this scenario?
A. nervous system → musculoskeletal system → circulatory system → nervous system
B. nervous system → musculoskeletal system → nervous system → musculoskeletal system
C. musculoskeletal system → nervous system → circulatory system → musculoskeletal system
D. musculoskeletal system → circulatory system → musculoskeletal system nervous system

Answer 1

The best option that identifies a pathway of systems in the rider's body, as described in this scenario, is:

B. nervous system → musculoskeletal system → nervous system → musculoskeletal system.

This pathway reflects the sequence of actions and feedback involved in the process. The rider's nervous system sends signals to the musculoskeletal system to pedal and then to stop pedaling, responding to the need to stop the bicycle. As she stops pedaling and moves her foot to the ground for balance, the nervous system continues to function in guiding her stabilization, and confirmation of movements involves continuous feedback between these systems.
