What cause a nerve impulse move along the nerve fiber?

Electrical diferences.


What causes a nerve impulse move along the nerve fiber?

Electrical diferences.


When a muscle contracts it does what?

In order for a muscle to contract, the brain sends a nerve impulse to the muscle it wants to contract. The nerve impulse triggers the potassium inside the muscle fiber cell to switch places with the calcium outside the cell wall, thereby feeding the cell and contracting the muscle. A second nerve impulse from the brain triggers the calcium to switch places with the potassium, releasing the contracted muscle.


What is the difference between synaptic and nerve impulse transmission?

Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.


What must be present for a nerve impulse to begin?

each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.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.


What steps involved in transmitting the impulse from one neuron to another and then to the muscle fiber?

When a change in the environment that initiates the transmission of an electrochemical charge along a neuron is known as?

A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse. &/or "nerve impulses" or "spikes".


Macroscopic neurology - trace impulse macroscopically through the nerveous system from the brain to the muscle?

Is the velocity of a nerve impulse greater than electrical conduction's?

yes


Which muscle trait is the ability to respond to a stimulus such as a nerve or hormone?

Muscle excitability is the ability to respond to a stimulus, such as a nerve signal or hormone, by generating an electrical impulse that leads to muscle contraction. This trait allows muscles to react to signals from the nervous or endocrine systems to produce movement.


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.


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.
