What do sensory neurons primarily transmit?

Sensory neurons are specialized cells responsible for converting external stimuli from the environment into electrical signals that can be understood by the nervous system. They play a crucial role in how we perceive the world around us, relaying information related to senses such as sight, sound, touch, taste, and smell.

The information transmitted by sensory neurons allows the brain to interpret and respond to sensory input, facilitating interactions with the environment. This function distinguishes sensory neurons from other types of neurons, such as motor neurons, which send signals from the brain to the muscles, and interneurons, which communicate information within the brain and spinal cord.

In the context of the other options, those that discuss information flow from the muscles to the brain or within the brain focus on different components of the nervous system's overall function and do not accurately reflect the primary role of sensory neurons.
