Neurons that carry impulses toward the spinal cord and brain are known as what?

• A. Peripheral
• B. Efferent
• C. Afferent
• D. Unipolar

Answer: (C)

Neurons that carry impulses toward the spinal cord and brain are referred to as afferent neurons. Afferent neurons, also known as sensory neurons, are responsible for transmitting sensory information from the peripheral parts of the body to the central nervous system. This process allows the brain to interpret sensory stimuli, such as touch, pain, temperature, and other senses. In contrast, efferent neurons carry impulses away from the central nervous system to the muscles and glands, which is essential for initiating responses. Peripheral refers to the outer areas of the body, and while unipolar is a type of neuron classification based on structure, neither term specifically defines the direction of impulse transmission as afferent does. Therefore, the choice of afferent reflects the role of these neurons in the transmission pathway of sensory information towards the central nervous system.
