In a nervous pathway, which neuron carries the impulse from the spinal cord to the brain?

In a nervous pathway, the neuron that carries impulses from the spinal cord to the brain is the sensory neuron. This type of neuron is responsible for transmitting sensory information from sensory receptors to the central nervous system, which includes the spinal cord and the brain. When a sensory neuron receives a stimulus, it generates an electrical impulse and relays this information upwards towards the brain for processing.

The function of the sensory neuron is crucial as it allows the body to react appropriately to environmental changes. For example, if you touch something hot, sensory neurons will carry that pain signal from your hand through the spinal cord to the brain where the sensation is processed, leading to a rapid response. This emphasizes the role of sensory neurons in facilitating communication between the body and the brain.

While interneurons and motor neurons play vital roles in the nervous system, they do not specifically convey impulses from the spinal cord to the brain. Interneurons, for example, are primarily involved in processing information within the spinal cord and connecting different neurons, while motor neurons carry signals away from the central nervous system to effectors like muscles. Therefore, the select role of sensory neurons in transmitting data to the brain is what makes them the answer to the question.
