sensory information from any stimuli get carried out to the CNS by Afferent
Receptor
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
The term used to describe the signal received by the central nervous system from the peripheral nervous system is "afferent signals" or "afferent input." These signals carry sensory information from the body to the brain and spinal cord, allowing the central nervous system to process and respond to various stimuli.
External stimuli refer to any environmental factors or signals that can influence an organism's behavior, perception, or physiological responses. These stimuli can include sights, sounds, smells, temperatures, and other sensory inputs that come from outside the organism. In psychology and biology, understanding external stimuli is crucial for studying how organisms interact with their surroundings and adapt to changes in their environment.
Sensory receptors in our body detect external stimuli, such as light, sound, or touch. These stimuli are then converted into electrical signals that travel to the brain through the nervous system. In the brain, these signals are processed and interpreted, resulting in our perception of the stimuli as neutral energy.
Two examples of external stimuli are pain, and temperature.
False
Two examples of external stimuli are pain, and temperature.
Nervous System
Sensory neurons are responsible for relaying information about external stimuli such as heat to the brain. These specialized cells detect the stimulus and transmit signals to the central nervous system for processing and response.
The physiology of itching involves nerve signals being sent to the brain in response to external stimuli, such as allergens or irritants. This response triggers the sensation of itching, prompting the body to scratch the affected area to remove the irritant.
