Where is the point on axon that a signal can be transmitted?
Signals are transmitted along the axon at the axon terminals or synaptic boutons. These structures are located at the ends of axon branches and contain neurotransmitter-filled vesicles that are released into the synapse to communicate with neighboring cells.
What does homogeneous signal mean?
A homogeneous signal is a signal that is uniform or consistent throughout its entirety. In other words, all parts of the signal exhibit the same characteristics or properties without variation. This term is commonly used in signal processing and communication systems to describe signals that do not change in composition or structure.
What has to happen to sound wave before they can be transmitted by radiowaves?
Sound waves need to be converted into electrical signals before they can be transmitted by radio waves. This is typically done by using a microphone to capture the sound waves and convert them into electrical signals that can then be modulated onto a radio frequency carrier wave for transmission.
How does light trigger an action potential?
When light hits the retina, it is absorbed by specialized light-sensitive cells called photoreceptors. This causes a photopigment within the photoreceptor cells to change shape, setting off a series of biochemical reactions that ultimately lead to the generation of an electrical signal in the form of an action potential. This signal is then transmitted to the brain via the optic nerve for processing.
How is a nerve signal transmitted from the point of sense to the brain and back?
When a stimulus is detected by a sensory nerve ending, it creates an electrical signal that travels along the nerve fiber to the spinal cord or brain. In the brain, the signal is processed, and a response is generated. The response signal then travels back along motor nerves to the muscles or organs to carry out the appropriate action.
What is the electric signal that is transmitted throughout the body called?
Nerve impulses.
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What are the range of frequencies that can be transmitted called?
The range of frequencies that can be transmitted is called the bandwidth. It refers to the range of frequencies within a signal that can be effectively transmitted through a communication channel.
How is FM transmitted?
the digital signal is converted to analog signal after using by transmitted antenna
What is the name device of converts sound into electrical signal?
The device that converts sound into an electrical signal is called a microphone. It captures sound waves and converts them into an electrical signal that can be amplified, recorded, or transmitted.
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
Why is reflection of signal useful?
Reflection of a transmitted signal is the basic premise of radar and sonar.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
How is mobille phones signal transmitted?
Radio Waves
How is a signal transmitted from one neuron to another in the human brain?
In the human brain, a signal is transmitted from one neuron to another through a process called synaptic transmission. When an electrical signal, known as an action potential, reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synapse, the gap between neurons. These neurotransmitters then bind to receptors on the receiving neuron, causing a new electrical signal to be generated and continue the communication between neurons.
What happens to a signal when transmitted over long distances?
the signal goes out of sink due to refraction
How does a signal move through a neuron?
A signal moves through a neuron by traveling along the axon, which is a long, thin extension of the neuron. The signal is transmitted as an electrical impulse called an action potential. When the signal reaches the end of the axon, it triggers the release of neurotransmitters, which then carry the signal to the next neuron.
