What else can I help you with?
How is an impulse communicated from nerve cell to nerve cell?
Via chemical messangers that cross the synapse.
What influences the speed of a nerve impulse?
the diameter of an axon
Neurotransmitters are released from what end of an axon?
synaptic vesicles
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 membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
How do nerve impulses cross the gap between the axon and the next structure?
Curently unknown...
A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
What are mircroscopic fiber that carries the nervous impulse along a nerve cell?
axon
What is the material surrounding the axon that increases the speed of the nerve impulse?
The material surrounding the axon that increases the speed of the nerve impulse is called myelin. Myelin is a fatty substance that acts as an insulating layer, allowing for faster transmission of electrical signals along the axon.
Which of the following does not factor into the rate of impulse propagation?
One factor that does not influence the rate of impulse propagation is the size of the neuron. The rate of impulse propagation is determined mainly by the myelination of the axon, the presence of nodes of Ranvier, and the diameter of the axon.
Where is the neuron in the body?
Neuron is the nerve cells that carry messages to the brain .The various parts of neuron are dendrite ,axon ,nucleus , cell body and nerve ending . All the information from the environment is detected by the specialised tips of nerve cells .These receptors are usually located in our sense organs such as,nose , tongue and so on. The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that creates an electrical impulse . This impulse travels from the dendrite to the cell body , and then along the axon ,to its end .At the end of the axon , the electrical impulse sets of the release of some chemicals . These chemicals cross the gap or synapse, and start a similar electrical impulse in a dendrite of the next neuron . This is how nerve impulse travel in a body
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.
