Answer:
a) Divergence means many different muscles may be called into play.
Explanation:
The term that means many different muscles may be called into play is divergence.
Divergence refers to the spreading or branching out of nerve fibers or signals from a single source to multiple destinations or target muscles. In the context of muscle movement, divergence allows for the activation and coordination of numerous muscles to work together in performing a specific action or movement.
When a signal is sent from the central nervous system to initiate muscle contraction, it can spread or diverge to activate multiple muscles simultaneously. This coordinated activation of different muscles is essential for complex movements, such as reaching, grasping, or walking, which involve the simultaneous contraction of various muscle groups.
For example, when you reach out to pick up an object, multiple muscles in your arm, shoulder, and hand are called into play. The nerve signals from the brain diverge and activate the necessary muscles in a coordinated manner to achieve the desired movement.
In summary, divergence is the term used to describe the spreading or branching out of nerve signals to activate many different muscles simultaneously. This allows for the coordinated movement of multiple muscle groups in performing complex actions.
