Symbiosis describes a close and long-term interaction between different species. In a mutualism, both species benefit; in a commensalism, one species benefits while the other is not affected.

Answer:
Peripheral nerves contain processes of more than one of four afferent and three efferent cell columns
Explanation:
The peripheral nerves contains afferent and efferent processes of four afferent and three efferent cell columns. Hence, the function of peripheral nerves can be assessed by seeing the functions of the respective afferent and efferent cell columns. The afferent cell columns are axons of sensory neurons which collects any sensory information from the body and carry it to the spine for initiating reflex actions. Alternatively, the efferent cell columns are the axons of the spinal motor neurons which carry the motor signals for movement to the respective muscles.
