What type of neuron carries signals toward the central nervous system?

The type of neuron that carries signals toward the central nervous system is the afferent neuron. Afferent neurons, also known as sensory neurons, are responsible for transmitting sensory information from various parts of the body to the central nervous system (CNS). This includes signals from the skin, muscles, and organs that can convey sensations such as touch, temperature, pain, and proprioception.

Afferent neurons play a crucial role in how the brain perceives the external environment and internal body states, allowing it to process information and respond appropriately. This means that when an input, such as a tactile sensation or a pain signal, is generated, it is the afferent neurons that conduct these signals to the CNS for interpretation.

In contrast, efferent neurons (often identified with motor functions) transmit impulses away from the central nervous system to effector organs, such as muscles and glands. Interneurons, located entirely within the CNS, serve as connectors or relay points between afferent and efferent neurons. Motor neurons are a subset of efferent neurons specifically involved in executing motor responses. Understanding the specific roles of these neuron types helps clarify their functions in the nervous system.
