If dorsal nerve of spinal cord is broken down then its effect is
no impulse is transmitted
impulse is transmitted but slowly
impulse is transmitted fast
no effect on impulse

spinal cords consist of various types of neurons which basically include sensory neuron (resides on the dorsal side), Motor neuron(resides in ventral side) and interneuron(resides inside spinal cord especially in grey matter).
If the dorsal spinal cord is broken then it affects the functioning of the sensory neuron.
