The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
When an axon is not conducting a nerve impulse and there is more sodium outside the axon and more potassium inside the axon it is referred to as what?
When an axon is not conducting a nerve impulse and there is a higher concentration of sodium ions outside the axon and a higher concentration of potassium ions inside, it is referred to as the resting potential. During this state, the axon's membrane is polarized, with a negative charge inside relative to the outside. This resting potential is crucial for the generation of action potentials when the neuron becomes activated.
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
A neuron transmits a nerve impulse as a wave of?
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 begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse
What carries a nerve impulse from one neuron to annother?
Neurotransmitter.

WOULD A SUBSTANCE THAT DECREASES MEMBRANE PROBABILITY TO SODIUM INCREASE OR DECREASE THE PROBABILITY OF GENERATING A NERVE IMPULSE?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
A substance that decreases membrane permeability to sodium would decrease the generation of a nerve impulse. This is because sodium ions play a crucial role in depolarizing the membrane and initiating nerve impulses. By reducing sodium influx into the cell, the ability of the neuron to generate an action potential would be diminished.
What is a neuron that transmits a nerve impulse toward the central nervous system is called what?
A sensory neuron transmits a nerve impulse towards the central nervous system. These nerve cells activated by input, transmits sensory information.
Where does a nerve impulse start?
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
What type of nervous tissue that conducts a nerve impulse?
Neurons
What are impulses that are sent down a neuron?
These impulses are called Nerve impulse. Nerve impulse is wave of electrochemical change tha travels along the length of neuron. Electrical potentail of neuron when it is in unstimulated condition is -70 millivolts. In this state outside the membrane of neuron, concentration of positive ions is more than the inside of membrane. Inside the membrane potassium ions are more than sodium ions while outside the membrane sodium ions are more than the potassium ions present there. This balance is maintained by sodium-potassium pumps through which three sodium ions move outside and two potassium ions move inside the membrane at a time. During this activity ATPase (enzyme) breaks down the ATP into ADP and phosphate then energy is released. When a neuron is stimulated, stimulus causes its membrane to depolirized (sodium ions move inside and potassium ions move outside the membrane). The adjacent parts of membrane are also affected by this depolarization. The change travels along the neuron while the prior parts of membrane return to their original state.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
