Sensory stimuli are transmitted to the brain through specialized sensory receptors that convert environmental signals into electrical impulses. These impulses travel along sensory neurons, entering the central nervous system and reaching specific areas of the brain, such as the thalamus and sensory cortices. Here, the brain processes and interprets the information, allowing us to perceive and respond to our surroundings.

What are specialized cells that detect and transmit stimulus information to sensory nerves and the brain?
Specialized cells that detect and transmit stimulus information to sensory nerves and the brain are called sensory receptors. These cells are tuned to respond to specific types of stimuli, such as light, sound, touch, temperature, and chemical signals. Upon detecting a stimulus, sensory receptors convert the information into electrical signals, which are then transmitted through sensory nerves to the brain for processing and interpretation. Examples of sensory receptors include photoreceptors in the eyes, mechanoreceptors in the skin, and chemoreceptors in the nose and mouth.
What process describes the conversion of an external stimulus to an internal action potential?
The process is known as sensory transduction. It involves converting an external stimulus, such as light or sound, into an electrical signal (action potential) in sensory neurons. This electrical signal is then transmitted to the brain for further processing and interpretation.
What is the stimulus and response pathway?
The stimulus and response pathway involves the process by which an organism detects a stimulus and then responds to it. This begins with sensory receptors detecting a change in the environment (the stimulus), which sends signals through sensory neurons to the central nervous system. The brain processes this information and generates a response, which is transmitted through motor neurons to effectors, such as muscles or glands, resulting in a physical reaction. This pathway is essential for survival, enabling organisms to adapt to their surroundings.
What are your body's response to stimuli coordinated by?
Your body's response to stimuli is coordinated by the nervous system. When a stimulus is detected by sensory receptors, the information is transmitted to the brain and spinal cord for processing. The nervous system then sends signals to muscles, glands, or other parts of the body to respond appropriately to the stimulus.
What is touch stimulus?
Touch stimulus refers to the sensory input received through the skin and other tissues when they come into contact with an object or surface. This type of stimulus is detected by specialized sensory receptors, such as mechanoreceptors, which respond to pressure, vibration, and texture. The information gathered is then transmitted to the brain, where it is interpreted, allowing us to perceive sensations like warmth, cold, pain, and pressure. Touch is a crucial aspect of human interaction and helps in understanding our environment.
How does a stimulus create a response?
A stimulus triggers a signal in sensory receptors, which is then transmitted through the nervous system to the brain. The brain processes this signal and initiates a response by sending signals to the appropriate muscles or glands to react to the stimulus.
The process of receiving and representing stimulus energies by the nervous system is called?
The process of receiving and representing stimulus energies by the nervous system is called sensory transduction. This is where sensory receptors convert physical or chemical stimulus energy into electrical signals that can be transmitted and processed by the brain.
Is tasting a lemon a stimulus?
Yes, tasting a lemon is a sensory stimulus that triggers a response in the taste receptors on the tongue. The sourness of the lemon elicits a specific taste sensation that is transmitted to the brain for interpretation.
What are specialized cells that detect and transmit stimulus information to sensory nerves and the brain?

Examples of sensory receptors include photoreceptors in the eyes, mechanoreceptors in the skin, and chemoreceptors in the nose and mouth.
What is required in order for a stimulus to be perceived?
For a stimulus to be perceived, it must first be detected by sensory receptors, which convert the physical energy of the stimulus into neural signals. These signals are then transmitted to the brain, where they are processed and interpreted. Additionally, attention and prior experiences can influence perception, as they shape how we interpret sensory information. Overall, the interaction between the stimulus, sensory receptors, neural pathways, and cognitive processes is essential for perception to occur.
What is the stimulus that triggers responses in the nervous system?
The stimulus that triggers responses in the nervous system is typically a sensory input, such as touch, sound, light, or chemicals, that is detected by sensory receptors in the body. This information is then transmitted to the brain and spinal cord, where it is processed and elicits a response from the nervous system.
What process describes the conversion of an external stimulus to an internal action potential?
The process is known as sensory transduction. It involves converting an external stimulus, such as light or sound, into an electrical signal (action potential) in sensory neurons. This electrical signal is then transmitted to the brain for further processing and interpretation.
When a stimulus is converted into a sensation the signal is then transmitted over a nervous system pathway to the?
When a stimulus is converted into a sensation, the signal is transmitted over a nervous system pathway to the central nervous system, specifically the spinal cord and then to the brain. The brain processes and interprets these signals, allowing us to perceive and respond to our environment. This complex pathway involves sensory neurons that relay information about the stimulus to the appropriate brain regions for further analysis and reaction.
How does the brain determine the location of a stimulus?
The brain determines the location of a stimulus through a process called sensory perception. This involves the integration of information from sensory receptors in the body, such as the eyes, ears, and skin, which send signals to the brain. The brain then processes and interprets these signals to create a spatial representation of where the stimulus is located in relation to the body.
What is the stimulus and response pathway?
The stimulus and response pathway involves the process by which an organism detects a stimulus and then responds to it. This begins with sensory receptors detecting a change in the environment (the stimulus), which sends signals through sensory neurons to the central nervous system. The brain processes this information and generates a response, which is transmitted through motor neurons to effectors, such as muscles or glands, resulting in a physical reaction. This pathway is essential for survival, enabling organisms to adapt to their surroundings.
What is the process of receiving stimulus energy called?
The process of receiving stimulus energy is called sensory reception. It involves the detection of sensory stimuli by sensory receptors in the body, which then transmit signals to the brain for processing and interpretation.
What is the intensity of a sensation is determined by what?
The intensity of a sensation is determined by the magnitude of the stimulus that evokes it. This can be influenced by factors such as the strength or amount of the stimulus, the sensory receptors involved, and the sensory pathways that transmit the signal to the brain.
