Aff erent (centripetal) pathways 

Eff erent (centrifugal) pathways

– transmit impulses from the CNS to eff ector organs in the periphery through eff erent neurones

– the eff erent neurone is the (somatomotor or visceromotor) lower motor neuron 

– the cell body of the eff erent neuron is located in the spinal cord, 

  its axon leaves the CNS to form the motor part of the peripheral nerve

1 Somatomotor tracts – innervate striated muscle

2 Visceromotor tracts – innervate smooth muscles and glandular cells

The nervous system constantly monitors changes of external and internal environ-
