What are neurons that change light into electrical impulses called?
Wiki User
∙ 12y ago
Neurons that convert light into electrical impulses are called photoreceptor cells. These specialized cells are found in the retina of the eye and are responsible for detecting light and converting it into signals that the brain can interpret as visual information.

How is contact between neurons accomplished?
Contact between neurons is achieved through structures called synapses. At a synapse, the electrical signal (action potential) in the presynaptic neuron triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing a change in its membrane potential and transmitting the signal.
What is an electrical charge that travels down the axon?
An electrical charge that travels down the axon of a neuron is called an action potential. It is a rapid change in electrical voltage that allows for communication between neurons.
How does your nervous system send signals to other body systems?
The nervous system sends signals to other body systems through electrical impulses known as action potentials. These signals travel along nerve cells, called neurons, and can communicate with other cells through neurotransmitters at synapses. This allows for coordination and control of various bodily functions.
What is the relationship between a stimulus and a nerve impulse?
A stimulus is any change in the environment that can activate a nerve ending, leading to the generation of a nerve impulse. A nerve impulse is an electrical signal that travels along a nerve cell in response to a stimulus. In other words, a stimulus triggers the generation of a nerve impulse.
In what ways are neurons unique?
Neurons are unique cells in the body because they specialize in transmitting electrical and chemical signals to other cells. They possess extensions called dendrites and axons that allow for communication with other neurons. Additionally, neurons have the ability to change and adapt their connections in a process called neuroplasticity.

How your brain and sensory organs get information from the outside world?
The sensory organs, such as the eyes, ears, nose, tongue, and skin, detect external stimuli like light, sound, smell, taste, and touch. They then convert these stimuli into electrical signals which are sent to the brain via the nervous system. The brain processes and interprets this information, allowing us to perceive and make sense of the world around us.

What energy change happens in your eyes?
In the eyes, light energy is converted into electrical signals by photoreceptor cells (rods and cones) in the retina. These electrical signals are then transferred to the brain through the optic nerve, where they are interpreted as visual information.
Electrical change in the neuronal membrane that is transmitted along axon is?
Action potential is the term for an electrical change in the neuronal membrane transmitted along an axon. The axon is part of a nerve cell that conducts impulses.

How does multiple sclerosis affect human health?
To create movement and simple bodly functions the neurons in our bodies need to relay messages to one another by electrical impulses. When someone has ms the body begins to destroy what is called myelin sheaths and the cells that produce myelin. The sheaths are then replaced by hard tissue which don't allow the electrical impulses to pass throu. Which can cause mild to sever muscle weakness abnormal sensations such as numbness or tingling over any part of the body, vision change, loss of coordination, tremors, paralysis, poor posture and bowel and bladder dysfunction. All depending on how sever the case is.
When a change in the environment that initiates the transmission of an electrochemical charge along a neuron is known as?
A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse. &/or "nerve impulses" or "spikes".
Which is the space that separates two neurons?
Synapses

What is the instrument called that can change electrical voltage?
Electrical voltage can be changed by a transformer.
How electrical activity of neurons might be measured?
The electrical activity of neurons can be measured using techniques such as electroencephalography (EEG), which records electrical activity of the brain through electrodes placed on the scalp. Another method is single-unit recording, where individual neuron activity is measured using microelectrodes inserted into the brain. Additionally, calcium imaging can be used to track neuronal activity by measuring changes in intracellular calcium levels.
