Final answer:
The correct option is 4). A 'sense organ' refers to sensory receptors with accessory tissues that aid in stimulus transduction. Sensory receptors are specialized to detect specific types of stimuli within their receptive fields and convert these stimuli into electrical signals in the nervous system.
Step-by-step explanation:
The term that refers to sensory receptors that are accompanied by accessory tissues which facilitate the transduction of a stimulus is a sense organ. Sensory receptors are either specialized cells associated with sensory neurons or the specialized ends of sensory neurons, which are a part of the peripheral nervous system, and are crucial for receiving information from the internal and external environments. The main function of these sensory systems is the translation of sensory input into electrical signals in the nervous system, a process known as transduction.
Each sensory receptor is specialized for the type of stimulus it detects, such as light, sound, or temperature, and has a receptive field within which it can respond to stimuli. For instance, gustatory receptors are sensitive to taste, but not to light. Furthermore, the accessory structures of sense organs might include components like the lens in the eye or the outer ear structure, all of which enhance the effectiveness of stimulus detection and transduction.
