Sensory Neurons Synapse in the CNS with an Interneuron Known

Question

Sensory neurons synapse in the CNS with an interneuron known as a
A) first-order neuron.
B) second-order neuron.
C) third-order neuron.
D) motor neuron.
E) efferent neuron.

Accepted Answer

Sensory neurons synapse in the CNS with a second-order neuron, which then transmits the signal to a third-order neuron. This third-order neuron then carries the signal to the appropriate area of the brain for processing and interpretation. The motor neuron is responsible for carrying signals from the CNS to muscles or glands, while efferent neurons are a type of motor neuron that specifically carry signals away from the CNS. First-order neurons refer to the initial sensory neurons that detect the stimulus.
