The electric signal transmitted throughout the body is called an action potential. This signal is generated by the movement of ions across the cell membrane of neurons and muscle cells, leading to depolarization and repolarization of the cell. Action potentials allow for the rapid communication between cells, enabling processes such as muscle contraction and nerve impulse transmission.
The absorption of a neurotransmitter after it has transmitted a neural impulse is called "reuptake." During reuptake, neurotransmitters are taken back into the presynaptic neuron, where they can be recycled and repackaged for future use. This process helps terminate the signal between neurons and regulates the levels of neurotransmitters in the synaptic cleft.
In nerve cells, electrical signals are transmitted away from the nucleus primarily through structures called axons. The axon conducts action potentials, which are rapid changes in electrical potential, allowing the signal to travel along its length. At the axon terminals, the signal is then transmitted to other cells, such as other neurons or muscle cells, through the release of neurotransmitters. This process is essential for communication within the nervous system.
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.
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.
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.
Nerve impulses.
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
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.
the digital signal is converted to analog signal after using by transmitted antenna
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.
Analog signals are transmitted as electrical waves.
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
Reflection of a transmitted signal is the basic premise of radar and sonar.
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.
Radio Waves
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.
the signal goes out of sink due to refraction
