The speed of nerve impulse transmission through the axon of a sensory neuron will be quickest in?
Biology103oh
I'm guessing; "myelinated nerve fibres" contrary to the much slower "non-myelinated nerve fibres"

Where does the nerve impulse travel from the reflex arc?
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
How does the structure of the sensory neurone maximise the speed of an impulse passing through it?
it lets it go throu faster like a pump
Sensory receptors of the ear?
The cochlea; sound wave are transferred through the ear canal and vibrated the ear drum which is connected to the cochlea and amplified the sound wave. When the sound wave reached the cochlea, sound wave is converted into nerve impulse and transferred through the nerve to the brain. Receptor is a converter of stimulus to electrical nerve impulse ; cochlea converted sound wave into nerve impulse and so cochlea is the sensory receptor of the ear.
How are signals sent through nerves to the rest of the body?
First stimulus received through the senses, Sense changed stimulus to an impulse than a sensory nerve capture the impulse, conducts the impulse to the spinal cord than the brain stem to the brain, then from the brain to the brain stem through the spinal cord to a motor nerve to a muscle or gland
What are the neurons that conduct impulses from a ganglion?
I'm not really sure what your asking...but a neuron sends an impulse because of a stimulus from the enviroment. The sensory neurons then pick up that stimulus and send the impulse down and it leaves through the axon where it is then pick up by another neurons dendrites.
What type of impulse travels through the posterior gray horn?
sensory
How does information from the sensory receptorsin the skin get to the brain?
The initial sensory receptor detects a change e.g temperature. This is sent as an electrical impulse via a series of sensory receptors to the spine, if there is a problem a reflex occurs. If there is no problem the impulse is transmitted to the brain through the spinal cord.
Where does the nerve impulse travel from the reflex arc?
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
What is the range for nerve impulse transmission through the human body?
over 9000

Describe the path a nerve impulse travels through?
When an impulse travels to the brain, it is first received by sensory receptors, then sent through the neurons by an electrical current. When the neuron receives the signal from a sensory receptor or from another neuron, the nucleus processes the impulse and then sends it down the axon. When a neuron is resting, the inside of the cell has a negative charge caused by active transport of NA and K molecules. This is called the resting potential. When the impulse hits the axon, the electricity causes NA pumps to open, allowing a flow of positively charged the molecule into the cell, causing the charges to switch. This is called the action potential. As the impulse passes, the K pumps open, restoring the original charge. When the impulse reached the end of the axon, neurotransmitters chemically pass the impulse to the next neuron. ;
What is the path that nervous impulse takes through the nervous system?
sensory neurone --> enters spinal cord --> relay neurone --> brain(is not a reflex action) or motor neurone(if action is reflex)
What is the difference between motor and sensory neurons?
The main difference is that motor neurons move signals away from the central nervous system and spinal cord where as sensory neurons move signals towards the central nervous system and spinal cord.

Three differences between sensory neurone and motor neurone?
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
