The text explains the regulation of breathing through motor neurons controlled by voluntary and involuntary pathways. It details how unconscious rhythmic breathing is influenced by sensory feedback from arterial blood PCO2, pH, and PO2 receptors. The process involves the contraction and relaxation of skeletal muscles, controlled by somatic motor neurons in the spinal cord, which are influenced by the medulla oblongata and cerebral cortex. Normal respiratory movements are involuntary and autonomically carried out.
