Skeletal (or striated) muscles
The path of a voluntary impulse begins in the brain, where the decision to initiate movement is made. This signal travels down the spinal cord through motor neurons, which transmit the impulse to the relevant muscles. The muscles then contract in response, resulting in voluntary movement. This process involves several regions of the brain, including the motor cortex, which coordinates and executes the action.
No, throwing is a learned motor skill, not a reflex. Reflexes are automatic responses to stimuli, while throwing involves a conscious decision and coordinated movement.
A voluntary muscle performs movement on command. Involuntary muscle performs with out conscious command.
The phrase "Nothing starts to move without a being involved" suggests that action or change requires a conscious agent or entity to initiate it. This implies that motion or progress does not occur spontaneously; rather, it necessitates intention or involvement from a conscious being. In philosophical terms, it underscores the importance of agency in the process of transformation or movement in the universe.

Yes, skeletal muscles are under voluntary control, meaning that we can consciously decide when to contract or relax them to perform movements. This control is facilitated by the motor neurons in the brain and spinal cord that send signals to the muscles to initiate movement.
Yes, kicking a ball is a voluntary action typically controlled by the individual's decision-making process and executed through muscle movement. The act of kicking a ball requires coordination between the brain, nervous system, and muscles to determine when and how to initiate the movement.
Automatic movement is exactly what it sounds like it would be. These are movements that are done automatically without conscious thought.
Muscle cells contract, causing movement and our heartbeat.
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
The difference between a reflex and a voluntary muscle is simply that a reflex is autonomic response to a stimulus thus making it involuntary. This in direct contradiction to a voluntary muscle movement with is done by making the conscious decision to do so.
