What is a stimulus in the nervous system?
A stimulus is a change in the environment (either external or internal) that is detected by a receptor. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system where decision-making occurs.

What are the 5 types of stimuli?
Our brains commonly receive sensory stimuli from our visual, auditory, olfactory, gustatory, and somatosensory systems.
When the body receives stimuli which structure typically processes the stimuli?
Cells called receptors , which detect stimuli (changes in the environment). The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.
Which of the following is a category of stimuli?
1. Which of the following is a category of a stimuli? Explanation: Periodic stimuli occur at predictable time intervals. For example, the system may examine a sensor every 50 milliseconds and take action depending on that sensor value.
What are the two types of stimuli give examples?
External stimuli are changes outside the body, or knowledge that is passed to us through our senses. This could be cold or hot weather, light levels, or danger. Internal stimuli are changes to conditions inside the body, such as dangerous food in the stomach, viruses in the body, or lack of food or water.
What is stimuli give one example?
