State the three main parts of a neuron and describe how an impulse travels through a neuron?
Okay, information is received through the dendrites, and then moves on the the cell body. From there, the cell's axon passes the message on to other neurons or to muscles or glands.
List the cellular structures over which an impulse would pass?
In the body, an electrical impulse travels through the neurons, or nerve cells, to send signals to and from the brain. The Dendrites of the neuron accept the impulse, send it through the soma, down the axon, and to the axon terminal, where it'll be sent to the next neuron, almost instantly.
What is the space through which a nerve impulse passes from one nerve cell to another called?
The space through which a nerve impulse passes from one nerve cell to another is called a synapse. It is a small gap between neurons where neurotransmitters are released to transmit signals between the cells.
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
A neuron starts to fire an impulse by the influx of what ions?
A neuron fires an impulse by the influx of sodium ions into the cell. This creates a temporary change in the neuron's membrane potential, leading to depolarization and the generation of an action potential.

What is the first part of the Neuron to receive an impulse from an adjacent neuron?
The first part of the neuron to receive an impulse from an adjacent neuron is the dendrites. Dendrites are branch-like structures that extend from the neuron's cell body and are specialized to receive signals from other neurons. When a neurotransmitter is released from the adjacent neuron's axon terminal, it binds to receptors on the dendrites, initiating an electrical impulse that travels through the neuron.
What statements characterizes an excitatory neuron?
It sends an impulse back to the cell body of the neuron

What direction will a neuron impulse travel through sensory neuron?
A neuron's impulse travels in one direction, starting from the dendrites, where sensory information is received, and moving towards the cell body. From the cell body, the impulse continues down the axon, eventually reaching the axon terminals. This unidirectional flow is essential for the proper transmission of signals within the nervous system.
When a neuron transfers an impulse to another neuron or to a muscle cell what is that location that receives the impulse called synapse dendrite receptor NextReset?
The location where a neuron transfers an impulse to another neuron or to a muscle cell is called a synapse. At the synapse, the presynaptic neuron releases neurotransmitters that bind to receptors on the postsynaptic neuron or muscle cell, facilitating the transmission of the signal. This process is crucial for communication within the nervous system and between nerves and muscles.

What carries impulses away from neuron cell bodies?
The axon of the neurone carries the impulse away from the cell body. The axon of the neurone carries the impulse away from the cell body.
Dendrites function in the motor neuron?
To carry the nerve impulse from the CNS to the cell body
Describe the path a nerve impulse travels through?
When an impulse travels to the brain, it is first received by sensory receptors, then sent through the neurons by an electrical current. When the neuron receives the signal from a sensory receptor or from another neuron, the nucleus processes the impulse and then sends it down the axon. When a neuron is resting, the inside of the cell has a negative charge caused by active transport of NA and K molecules. This is called the resting potential. When the impulse hits the axon, the electricity causes NA pumps to open, allowing a flow of positively charged the molecule into the cell, causing the charges to switch. This is called the action potential. As the impulse passes, the K pumps open, restoring the original charge. When the impulse reached the end of the axon, neurotransmitters chemically pass the impulse to the next neuron. ;
