What else can I help you with?
An electrical impulse moving down an axon is called what?
An electrical impulse moving down an axon is known as an action potential.
Which of the stimuli resulted is the most effective nerve stimulation?
Electrical stimulation is typically the most effective method for nerve stimulation as it can directly trigger action potentials in the nerve fibers. Light and chemical stimuli can also stimulate nerves but are generally not as precise or efficient as electrical stimulation.
Is a nerve message also called a synapse?
Nerve messages are called an impulse. Synapses are the space between two axons.
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.
Which of the following types of nerve fiber possesses the fastest speed of impulse propagation?
Myelinated A fibers have the fastest speed of impulse propagation among nerve fibers.
Where is the mechanical stimulation of sound converted into a nerve impulse?
In The Hair cells.
A nerve impulse consists of a wave of?
Action Potentials
What is the amount of stimulation required to intiate a nerve impulse called?
Neuron has to be stimulated to the point of it's threshold in order for an action potential to be initiated and transmitted
Describe how the nerve impulse travels in the heart?
The brain can influence the heart in two ways. Sympathetic and parasympathetic stimulation. Parasympathetic stimulation of the heart is through the vagus nerve. Sympathetic stimulation of the heart is via cervical and thoracic splanchnic nerves. The heart has its own pacemaker cells, so the brain only changes the rate and contractility of the heart.
What is quicker a nerve impulse or a hormone?
nerve impulse
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What is transcutaneous electrical nerve stimulation also called?
Electrical nerve stimulation
What are the sources of stimulation that start a nerve impulse?
Sources of stimulation that can start a nerve impulse include chemical signals (neurotransmitters released at synapses), physical stimuli (such as pressure or temperature changes acting on sensory receptors), and electrical signals (generated by neighboring neurons or external electrical sources). These stimulations can trigger the opening of ion channels in the neuron's membrane, leading to changes in membrane potential and initiation of an action potential.
How does a nerve impulse follow all or nothing principle?
How does a nerve impulse follow the all-or-nothing principle???
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
