If dorsal nerve of spinal cord is broken down then its effect is :

Options

  1. Ano impulse is transmitted
  2. Bimpulse is transmitted but slowly
  3. Cimpulse is transmitted fast
  4. Dno effect on impulse

Correct answer

A. no impulse is transmitted

Step-by-step solution

Spinal nerve is a mixed nerve which arises from grey matter of spinal cord. Spinal nerves have two roots. The dorsal root is sensory and the ventral root is motor. If dorsal nerve of spinal cord is broken down, the pathway of nerve will break, so, no impulse will transmitted.
