Question

Quizplus · Accepted Answer

Sensory neurons are responsible for transmitting sensory information, such as pain signals, from the peripheral nervous system (including the skin) to the central nervous system. Therefore, in this scenario, the sensory neurons would be responsible for sending messages about the pain from the sunburn to the woman's central nervous system. Motor neurons are responsible for transmitting messages from the central nervous system to the muscles, while synaptic neurons are responsible for transmitting messages between neurons. Association neurons are also called interneurons and are responsible for relaying information between sensory and motor neurons in the central nervous system.
