The nerves that carry impulses towards the Central Nervous System (CNS) only are known as afferent nerves. These nerves are responsible for transmitting sensory information from the peripheral parts of the body to the CNS. This allows the brain and spinal cord to process and respond to various stimuli such as touch, temperature, and pain.
Afferent nerves are also referred to as sensory nerves. They play a crucial role in the body’s ability to perceive and react to its environment. Unlike efferent nerves, which carry signals from the CNS to the muscles and glands, afferent nerves only carry information towards the CNS.
In summary, the correct answer is b) afferent nerves.
