What type of structure in nerve cells must grow in order for sensory information to be relayed to the spinal cord?
larisa86 [58]

For sensory information to be relayed the nerve cells should have an axon.

<u>Explanation</u>:

  • Nerve cells or neurons play a critical role in transmitting signals from various sense organs of the body to the spinal cord where it is processed.
  • Neurons have different parts - the dendrites which are tiny branches that receive incoming signals from the body, the nucleus, and the axon.
  • The axon is a long fiber that is covered by a protective layer called myelin sheath. It is this structure of the nerve cell or neuron that helps transmit signals to the Central Nervous System of which the spinal cord is a part.
