What is an example of nerve impulse?

For example, if you touch a hot stove, nerve cells in your fingers will fire, sending impulses through the nerves in your hand, quickly reaching your brain, which will send a signal back down to move your hand away from the heat.

What are the different types of nerve impulses?

Functionally, neurons are classified as afferent, efferent, or interneurons (association neurons) according to the direction in which they transmit impulses relative to the central nervous system. Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS.

What is nerve impulse answer?

A nerve impulse is the way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The action potential is the result of ions moving in and out of the cell.

What kind of impulse is a nerve impulse?

The nerve impulse is a wave of depolarization traveling along the axon of the motor nerve such that the resting membrane potential of about −70 millivolt is reversed, becoming briefly positive.

What is the correct order for nerve impulses?

The correct order of the parts of the neuron with respect to the direction of the action potential is “dendrite, cell body, axon, synapse”. The dendrites receive impulses from the synapse of another neuron. Then these impulses are propagated towards the neuron cell body then to the axon.

What is the pathway of nerve impulses?

The pathway of a nervous impulse is from one neuron to the next until it reaches skeletal, cardiac or smooth muscle. The impulse begins or is propagated from the nerve cell body or the axon hillock to be precise and travels to either another neuron synapse or a terminal bouton at the neuro-muscular junction.

How does a nerve impulse work?

A nerve impulse is the way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The action potential is the result of ions moving in and out of the cell.

How does the nerve impulse travel along the neuron?

A nerve impulse may be defined as wave of depolarization of the membrane of the nerve cell. The nerve impulse travels along a neuron or across a synapse (junction), between one neuron and another, or between a neuron and an effector, such as a muscle or gland.
