Destruction of the anterior horn cells of the spinal cord would result in the loss of:
Correct answer: D. Voluntary motor impulses
- A. Commissural impulses
- B. Integrating impulses
- C. Sensory impulses
- D. Voluntary motor impulses
Explanation
Peripheral motor nerves carry motor impulses from the spinal cord to voluntary muscles. The destruction of the cells of the anterior horn of the spinal cord will result in the loss of voluntary motor impulses. This is because the cells of the anterior horn (also called the anterior gray column), which is the front column of gray matter in the spinal cord, contain motor neurons that innervate the axillary muscles.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
