Answer

The damaged neuron is a motor neuron.

Solution

In this scenario, Mr. Warren has spinal cord damage that prevents nerve impulses from being carried from the Central Nervous System (CNS) to muscles or glands. The type of neuron responsible for carrying impulses from the CNS to muscles or glands is known as a motor neuron.
Here’s a brief explanation of the options:
  • Afferent neurons: These are sensory neurons that carry signals from sensory receptors to the CNS.
  • Sensory neuron: This is another term for afferent neurons, which also carry information from the senses to the CNS.
  • Motor neuron: These neurons transmit impulses from the CNS to effectors (muscles or glands), which is what is affected in Mr. Warren’s case.
  • Axon terminals: These are the endpoints of a neuron where neurotransmitters are released, not a type of neuron.
Therefore, the specific type of neuron that has been damaged is the motor neuron.

Beyond the Answer

Motor neurons have been damaged in Mr. Warren’s case. These neurons are responsible for carrying nerve impulses away from the central nervous system (CNS) to the muscles and glands. When they are impaired due to spinal cord damage, the brain’s ability to control muscle movements is hindered, leading to difficulties in coordination and mobility.
In this condition, Mr. Warren’s body may still receive sensory information (via afferent neurons), but without functional motor neurons, he won’t be able to respond with physical actions. This highlights the critical role motor neurons play in the neural pathway and the overall functioning of the nervous system.
