A neuron transmits a nerve impulse as a wave of electrical activity called an action potential. This action potential travels along the length of the neuron's axon and triggers the release of neurotransmitters at the synapse, allowing communication between neurons.

What is the name for the impulse generated when a neuron fires?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
Sensory receptors of the ear?
The ear contains sensory receptors such as hair cells in the cochlea, responsible for detecting sound waves, and the semicircular canals, which detect changes in head position and movement to help with balance. These receptors convert physical stimuli into electrical signals that are transmitted to the brain for interpretation.
A Traveling wave of excitation is what you know as?
A traveling wave of excitation is commonly known as an action potential. It is a brief electrical impulse that travels along the length of a nerve cell or muscle fiber, allowing for rapid communication and coordination within the body.
The point at which an impulse from one nerve cell is communicated to another nerve cell is what?
The point at which an impulse from one nerve cell is communicated to another nerve cell is called a synapse. This is where neurotransmitters are released from the presynaptic neuron, cross the synaptic cleft, and bind to receptors on the postsynaptic neuron, transmitting the signal.
What is the first wave of an ECG?
The first wave of an ECG is the P wave, which represents atrial depolarization as the electrical impulse spreads through the atria. It is the initial wave seen in a normal heart rhythm.
What A wave pattern travels down the length of the axon of a cell.?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
A wave pattern travels down the length of the axon of what kind of cell?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
A nerve impulse consists of a wave of?
Action Potentials
What is impulse in the nervous system?
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.
What is the name for the impulse generated when a neuron fires?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
Write note on nerve impulse?
A nerve impulse is an electrical signal that travels along nerve cells, allowing for communication between different parts of the body. It is generated when there is a change in the voltage across the cell membrane, causing a wave of depolarization and repolarization to propagate down the length of the neuron. Nerve impulses play a crucial role in various bodily functions, including movement, sensation, and communication between the brain and other organs.
The events of a nerve impulse?
A nerve impulse is generated when a neuron receives a signal, causing a change in the neuron's membrane potential. This change triggers the opening of voltage-gated ion channels, allowing ions to flow in and out of the neuron. This flow of ions creates an electrical signal that travels down the length of the neuron as the impulse.
Traveling wave of excitation is known as?
Traveling wave of excitation is known as an action potential in nerve cells or an impulse in muscle cells. This wave allows for communication and coordination of cell activities in the body.
Why you hear a sound when you clap your hands together.?
the hands make a compression wave that travels through the air. Your ears pick up that compression wave and turns it into a neuron impulse that your brain registers as sound.
Sensory receptors of the ear?
The ear contains sensory receptors such as hair cells in the cochlea, responsible for detecting sound waves, and the semicircular canals, which detect changes in head position and movement to help with balance. These receptors convert physical stimuli into electrical signals that are transmitted to the brain for interpretation.
A Traveling wave of excitation is what you know as?
A traveling wave of excitation is commonly known as an action potential. It is a brief electrical impulse that travels along the length of a nerve cell or muscle fiber, allowing for rapid communication and coordination within the body.
How is nerve impulse conducted along a myelinated nerve fiber?
Nerve impulses are conducted along myelinated nerve fibers by "jumping" between the gaps in the myelin sheath called Nodes of Ranvier. This process is known as saltatory conduction and allows for faster transmission of the nerve impulse compared to unmyelinated fibers.
