What name is given to a message that travels around the body in a nerve?
An electrical signal traveling along a nerve is called a nerve impulse or action potential.
How is a nerve signal transmitted from the point of sense to the brain and back?
When a stimulus is detected by a sensory nerve ending, it creates an electrical signal that travels along the nerve fiber to the spinal cord or brain. In the brain, the signal is processed, and a response is generated. The response signal then travels back along motor nerves to the muscles or organs to carry out the appropriate action.
What travels along the optic nerve from the eye to the brain?
It is a nervous impulse, which is somewhat like an electrical current that sends to the specialized brain receptor the image that you are seeing at that moment. This is one of the most complex mechanism of the human body. The vision.
This nerve travels from the lower back through the buttocks and into the leg Add an A to its name and you have a painful lumbar disorder What nerve is this?
The nerve is the sciatic nerve. Adding an "A" to its name gives you sciatica, which is a painful condition caused by compression or irritation of the sciatic nerve, resulting in symptoms like sharp pain, numbness, or tingling along the nerve's pathway.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What is the direction of impulse in a neuron?
A nerve impulse travels toward the actual nucleus itself to pass information.

What are the main roles played by axon?
conducts electrical impulses away from the neuron's cell body or soma. It is basically what the nerve impulse travels along.
Mechanism of nerve conduction?
Nerve conduction involves the transmission of electrical impulses along the length of a nerve fiber. When a nerve is stimulated, sodium ions rush into the nerve cell, causing a change in electrical charge. This creates an action potential that travels down the nerve fiber, activating adjacent areas and allowing the signal to be transmitted. Once the impulse reaches its destination, neurotransmitters are released to stimulate the next nerve cell or muscle fiber.

a nerve impulse
Which theory best explains how you perceive low pitched sounds?
The frequency theory suggests that the perception of low-pitched sounds is based on the rate at which the auditory nerve fires signals to the brain, corresponding to the frequency of the sound wave. This theory proposes that the pitch of a sound is encoded in the frequency of nerve impulses traveling along the auditory nerve.
Which nerve travels down the back side of the thigh?
Many do, but the sciatic nerve is the largest.
How does a nerve transmit information?
Nerves transmit information through a process called action potential, which involves the movement of ions across the neuron's membrane. When a neuron is stimulated, sodium channels open, allowing sodium ions to flow into the cell, depolarizing the membrane. This change in electrical charge travels along the nerve fiber as an action potential, ultimately reaching the nerve terminal. Here, neurotransmitters are released into the synapse, transmitting the signal to the next neuron or target tissue.
