1 C1 and C2 (the first two cervical nerves) control the head. 2  C3 and C4 help control the diaphragm (the sheet of muscle that stretches to the bottom of the rib cage and plays an important role in breathing and respiration).atch Cervical Radiculopathy Video. In addition to the seven cervical vertebrae, cervical anatomy features eight cervical nerves (C1-C8) that branch off of the spinal cord and control different types of bodily and sensory activities. Each cervical nerve is named based on the lower cervical vertebra that it runs between.
The motor system is organized hierarchically, with more complex motor tasks initiated at higher levels [1] . Very simple motor commands such as reflexes or scratching are controlled by the spinal cord. Other reflexes such as breathing are controlled at the level of the brain stem, located at the base of your brain.Various regions in the brain stem also control posture. Our cerebral cortex controls the most complicated motor tasks, including goal-directed behavior.If we voluntarily want to act on the sensory information, then our brain sends signals via the pyramidal motor pathway to our muscles.he motor system is organized hierarchically, with more complex motor tasks initiated at higher levels [1] .
