Interoceptor refers to a type of sensory receptor that detects internal bodily sensations such as hunger, pain, and thirst. Some synonyms for interoceptor include visceral receptor, internal sense organ, and organ of internal sensation. These receptors are responsible for regulating internal processes such as digestion, respiration, and blood pressure. They are present in various organs such as the stomach, lungs, and heart. Interoceptors receive signals from the autonomic nervous system and help maintain homeostasis in the body. Understanding the functions of interoceptors can aid in the diagnosis and treatment of various conditions, such as gastrointestinal disorders and cardiovascular disease.
