Final answer:
Activation of interoceptors results in sensations such as visceral pain and bladder pressure.
Step-by-step explanation:
The sensations that result from activation of interoceptors include visceral pain and bladder pressure. Interoceptors are sensory receptors that are found in the walls of visceral organs, such as the kidneys and urinary bladder. These receptors are responsible for detecting sensations related to the internal environment of the body, such as pain and pressure.
