Question

List the four steps, outlined in the first column of page 101, that lead to body movement."

Answer 1

The four steps that lead to body movement typically include the firing of a nerve impulse in the brain, the transmission of this impulse to the spinal cord, the signal being sent to a muscle cell, and finally the contraction of the muscle cell which causes movement.

Step-by-step explanation:

The process leading to body movement involves several steps that you can find outlined in the text. While the specific four steps are not provided in the reference material given, typically, the following steps are involved in creating movement in the human body:

1. A neuron in the cerebral cortex fires a nerve impulse.
2. This impulse is transmitted to a neuron in the spinal cord.
3. The spinal neuron then sends the signal to a muscle cell.
4. Finally, the muscle cell contracts and causes the body movement.

This sequence describes the pathway from decision to movement, which is essential for voluntary motions such as running or lifting an object.
