Which of the following is responsible for the movement of leg muscle in a football game?
A. Voluntary actions
B. Involuntary actions
C. Reflex actions
D. All of the above

Hint: Voluntary actions are the action which is initiated by our consciousness which is controlled by the Cerebrum. The cerebrum sends impulses to the effector's muscles through the spinal cord with the neurons. Involuntary actions take total control without consciousness and are under the control of the hindbrain and spinal cord. The reflex action is the rapid, spontaneous, involuntary motor response to a sensory stimulus.

Complete answer:
The movement of skeletal muscle is under the control of voluntary actions. The legs contain skeletal muscle, so for its movement in the football match, it requires voluntary actions. Hence option A is the correct answer.

Additional Information:
The skeletal muscles of the leg are under the control of the motor cortex present in the frontal lobe of the cerebrum of the Forebrain. That means it is neither in the control of the hind brain or spinal cord.
Hence option B is incorrect.

The reflex action is also involuntary but the movement of the leg is not.
hence the option C is incorrect.

As option B and option C are incorrect hence option D is also incorrect.

Note:
Reflex action can be of two types – Unconditioned reflex (reflex present from birth) and Conditioned reflex (reflexes that are acquired by an individual during its lifetime through willful repeated practices). Unconditioned reflexes can be classified based on the location of the receptors – Superficial reflex (located on skin and eyes), Deep reflex (receptor beneath the skin), and Visceral reflex (receptor in the visceral organ).
