What else can I help you with?
What happens to a muscle when an electrical impulse from a nerve stops?
When the electrical impulse from a nerve stops, the muscle relaxes and returns to its resting state. This is because the nerve impulse initiates the release of calcium ions in the muscle cells, leading to muscle contraction. When the nerve impulse stops, the calcium ions are reabsorbed, causing the muscle to relax.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
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 influences the speed of a nerve impulse?
the diameter of an axon
Does the nerve impulse reaches the brain during reflex arc?
No, during a reflex arc, the nerve impulse does not reach the brain before the reflex action occurs. Instead, the impulse travels from the sensory receptor through the spinal cord to the motor neurons, which directly trigger a response. This allows for a quick reaction to stimuli, bypassing the brain for immediate response. The brain may become aware of the stimulus and the reflex action afterward.
During a reflex the nerve impulse reaches?
the brain

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 happens for the perception of sensation to take place?
stimulus present, receptor activated, nerve impulse conduction
How does a nerve impulse follow all or nothing principle?

Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
What is a nerve impule transmitted by axons?
It is called a nerve impulse.
The neurotransmitters of a neutron enable a nerve impulse to do what?

What nerve receive the impulse?
receptors.
