Across
- 3. Receptors – Specialized cells, or nerve endings, that detect specific internal or external stimuli (such as light, sound, heat, or pressure) and convert them into electrical signals (action potentials)
- 7. – Describes how a stimulus leads to changes in your body, such as neural activity, hormone release, or sensory receptor activation
- 10. – The minimum level of stimulus intensity required to produce a detectable response in an organism
- 12. – The process of organizing, interpreting, and experiencing sensory information to understand the environment
- 13. Stimulus – The immediate sensory information, such as light, sound, or pressure, that directly activates sensory receptors (eyes, ears, skin)
- 14. Stimulus – Physical objects, events, or sounds outside the body that can be perceived as sources of sensory information
- 15. – The physical process of sensory receptors detecting external stimuli (light, sound, smell)
Down
- 1. – The relationship between how the body functions internally and how an organism behaves externally
- 2. Process – The step in sensation where sensory receptors detect and respond to physical energy from the environment, the moment your body first picks up a stimulus, before your brain interprets it
- 4. – How an external or internal stimulus (something that happens or is experienced) leads to a behavior (a response or action)
- 5. Processing – The way the nervous system receives, interprets, and transmits information through signals between neurons
- 6. Potential – An action potential is the rapid electrical impulse that travels along the neuron, carrying a message from one part of the cell to another
- 8. – The transformation of environmental energy into electrical energy
- 9. Magnitude – How intense or strong a stimulus is perceived to be by an individual, rather than its actual physical intensity
- 11. – The step that triggers neurons to send signals. Without it, communication in the nervous system would not occur.
