Which type of neuron is responsible for conducting impulses away from the brain?

The type of neuron responsible for conducting impulses away from the brain is known as a motor neuron. Motor neurons play a critical role in the nervous system by transmitting signals from the central nervous system (CNS), which includes the brain and spinal cord, to various muscles and glands throughout the body. This process enables movement and responses to stimuli.

Motor neurons can be classified into upper motor neurons, which originate in the brain, and lower motor neurons, which extend from the spinal cord to the muscles. When the brain sends a signal through these motor neurons, it triggers the contraction of muscles, allowing for voluntary and involuntary movements.

Interneurons, on the other hand, primarily function as connectors between sensory and motor neurons within the CNS, facilitating communication and processing between different parts of the nervous system. Sensory neurons, in contrast, are responsible for carrying impulses from sensory receptors to the brain, providing information about the external and internal environment. Dendrites are not a type of neuron; rather, they are extensions of neurons that receive signals and conduct them toward the cell body. Understanding the distinct functions of these different types of neurons highlights why motor neurons specifically are vital for conducting impulses away from the brain.
