What Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers in the rods and cones?
When light energy enters the eye and triggers phototransduction in rods and cones, it causes a hyperpolarization of these photoreceptor cells. This change in membrane potential leads to a decrease in the release of the neurotransmitter glutamate. As a result, bipolar cells, which are influenced by the levels of glutamate, either depolarize or hyperpolarize depending on whether they are ON or OFF bipolar cells, ultimately transmitting neural impulses to ganglion cells and onward to the brain.

What are responsible for converting sensory messages into neural impulses?
Sensory receptors, such as photoreceptors in the eyes, mechanoreceptors in the skin, and chemoreceptors in the nose, are responsible for converting sensory messages (like light, pressure, and chemicals) into neural impulses. These neural impulses are then transmitted to the brain for processing and interpretation.
Incoming neural impulses are received by the of a neuron?
Incoming neural impulses are received by the dendrites of a neuron. Dendrites are branch-like extensions that receive signals from other neurons and transmit them towards the cell body. Once the signals are received by the dendrites, they are integrated in the cell body before being transmitted down the axon.
In general neural messages are received by the and transmitted by the?
In general, neural messages are received by the dendrites of a neuron and transmitted by the axon. Dendrites are specialized structures that detect signals from other neurons, while the axon carries electrical impulses away from the neuron's cell body to communicate with other neurons or target tissues. This process forms the basis of neural communication within the nervous system.
What stimulates sensory impulses at receptors?
Sensory impulses at receptors are typically stimulated by specific environmental stimuli such as light, sound, touch, temperature, or chemicals. These stimuli activate specialized receptors on sensory neurons, which then generate neural signals that are transmitted to the brain for further processing and interpretation.
The mechanical vibrations triggered by sound waves are transformed into neural impulses by what?
hair cells
The process by which neural impulses are transmitted through the nervous system is best described as?
The process by which neural impulses are transmitted through the nervous system is best described as electric impulses. Any damage to a nerve in the system will cause a breakdown in communication between nerve ending and the brain.
What are responsible for converting sensory messages into neural impulses?
Sensory receptors, such as photoreceptors in the eyes, mechanoreceptors in the skin, and chemoreceptors in the nose, are responsible for converting sensory messages (like light, pressure, and chemicals) into neural impulses. These neural impulses are then transmitted to the brain for processing and interpretation.
Why electrical impulses are referred to as neural impulses?
Electrical impulses are referred to as neural impulses because a neural impulse cause electrical impulses. Neurons use electrical impulses to send messages.
How are neural impulses generated?
Neural impulses are generated when a neuron receives signals from other neurons or sensory receptors, causing a change in its membrane potential. This change in membrane potential triggers an action potential, a rapid electrical signal that travels down the axon of the neuron. This action potential then triggers the release of neurotransmitters at the synapse, allowing the signal to be passed on to other neurons.
Which structure if the neuron transmits an impulse through the myelin sheath?
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
What are also called neural impulses?
Action potential is a neural impulse.

This process forms the basis of neural communication within the nervous system.
Does neural impulses travel faster than hormonal messages?
Yes, neural impulses travel faster than hormonal messages. Neural impulses are electrical signals that travel along nerve cells at speeds of up to 120 meters per second, while hormonal messages are transmitted through the bloodstream at slower speeds, ranging from a few centimeters to a few meters per second.
Which structure is responsible for transducing light into neural impulses?
The retina is responsible for transducing light into neural impulses. It is a layer of tissue located at the back of the eye that contains photoreceptor cells (rods and cones) that convert light into electrical signals that can be processed by the brain.
A slap on the back is more painful than a pat on the back because a slap triggers?
A slap on the back is more painful than a pat on the back because a slap triggers more intense neural impulses. The slap cause more neuron to fire, and to fire more often.
A slap on the back is more painful than a pat on the back because a slap triggers what?
A slap on the back is more painful than a pat on the back because a slap triggers more intense neural impulses. The slap cause more neuron to fire, and to fire more often.
