Which type of nerve is responsible for carrying information from sensory receptors to the spinal cord and brain?

The correct response is based on the role of sensory nerves in the nervous system. Sensory nerves are specifically designed to carry information from sensory receptors, which detect stimuli such as touch, temperature, pain, and other sensory modalities, to the spinal cord and brain for processing. When these sensory receptors are activated, they generate signals that travel along sensory nerves, allowing the central nervous system to perceive and respond to the surrounding environment.

While afferent nerves typically also carry sensory information to the central nervous system, the term is more encompassing and can sometimes be used interchangeably with sensory nerves. Motor nerves, on the other hand, are responsible for conveying signals from the brain and spinal cord to the muscles, leading to movement. Reflex nerves relate to specific pathways involved in reflex actions, which are automatic responses that do not require conscious thought. Understanding these distinct functions clarifies why sensory nerves are the primary carriers of sensory information to the central nervous system.
