Which structure in a neuron helps to conduct a nerve impulse away from the cell body?
The axon of a neuron conducts electrical impulses away from the cell body. This is easy to remember because axon starts with an "a" for away.
Through which part of the neuron does an impulse leave the cell?
An impulse leaves the neuron through the axon, which is a long projection that carries electrical signals away from the cell body to other neurons or cells.
Which part of the neuron is responsible for generating a nerve impulse?
The axon is responsible for generating and transmitting a nerve impulse. It is a long, slender projection of the neuron that carries the electrical signal away from the cell body towards other neurons or muscles.
How do livng things respond to stimuli?
There are two types of responses to stimuli. 1)Deep response which requires integration by the brain such as thinking. 2)Simple response which is done by reflex arc. The reflex Arc is consisted if receptor, sensory neuron, relay neuron, motor neuron and effector which is either muscle or gland. For example in humans. If your hand touches a hot object. Heat receptors in your hand will act as sensor, passing an impulse by generating action potential in the sensory neuron. The sensory neuron passes the impulse to along it till reaching the spinal cord passing the impulse to the relay neuron by a process called synapse. The relay neuron synapse with motor neuron to pass the impulse to it. The end of the motor neuron is connected to the bi-ceps muscle in the arm. As the impulse reaches the end of the motor neuron it passes impulse to the muscle ordering it to contract, thus the hand is removed away from stimulus. This process take a fraction of a second.

What carries an impulse away from neuron?
The axon.
What carries impulses away from neuron cell bodies?
The axon of the neurone carries the impulse away from the cell body. The axon of the neurone carries the impulse away from the cell body.
Through which part of the neuron does an impulse leave the cell?
An impulse leaves the neuron through the axon, which is a long projection that carries electrical signals away from the cell body to other neurons or cells.
What part of the neuron conducts the nerve impulse?
Dendrite toward the cell body, axon away from the cell body.
Which part of the neuron is responsible for generating a nerve impulse?
The axon is responsible for generating and transmitting a nerve impulse. It is a long, slender projection of the neuron that carries the electrical signal away from the cell body towards other neurons or muscles.
What is the medical term meaning Nerves that carry impulses away from the CNS?
Efferent nerves.the motor neuron transmits the impulse away from the CNS and to the effector
Describe the pathway an impulse travels macroscopically through the nervous system from the brain to the muscle?
The NeuronThe cells that carry information through your nervous system are called neurons, or nerve cells. The message that a neuron carries is called a nerve impulse. The Structure of a Neuron:The structure of the neuron enables it to carry nerve impulses. A neuron has a large cell body that contains the nucleus, threadlike extensions called dendrites, and an axon. The dendrites carry impulses toward the neuron's cell body. The axon carries impulses away from the cell body. Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A neuron can have many dendrites, but it has only one axon. An axon, however, can have more than one tip, so the impulse can go to more than one other cell. Axons and dendrites are sometimes called nerve fibers. Nerve fibers are often arranged in parallel bundles covered with a connective tissue, something like a package of uncooked spaghetti wrapped in cellophane. A bundle of nerve fibers is called a nerve.Kinds of Neurons:Three kinds of neurons are found in the body-- sensory neurons, interneurons, and motor neurons.A sensory neuron picks up stimuli from the internal or external environment and converts each stimulus into a nerve impulse. The impulse travels along the sensory neuron until it reaches the interneuron, usually in the brain or spinal cord. An interneuron is a neuron that carries nerve impulses from one neuron to another. Some interneurons pass impulses from sensory neurons to motor neurons. A motor neuron sends an impulse to a muscle or gland, and the muscle or gland reacts in response.How a Nerve Impulse TravelsThe Synapse:What happens when a nerve impulse reaches the axon tip at the end of a neuron? At that point, the impulse can pass to the next structure. Sometimes the structure is a dendrite of another neuron. Other times, the structure is a muscle or a cell in another organ, such as a sweat gland. The junction where one neuron can transfer an impulse to another structure is called a synapse. (SIN aps). How an Impulse is Transferred:For a nerve impulse to be carried along at a synapse, it must cross the gap between the axon and the next structure. The axon tips release chemicals that carry the impulse across the gap.You can think of the gap at a synapse as a river, and an axon as a road that leads up to the riverbank. The nerve impulse is like a car traveling on the road. To get to the other side, the car has to cross the river. The car gets on a ferry boat, which carries it across the river. The chemicals that the axon tips release are like the ferry, carrying the nerve impulse across the gap.
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.
What are the two parts the neuron is split up into?
There are actually 3 parts to a neuron. The dendrites are tree branch like projections that receive nerve impulses from another neuron, the cell body that contains the nucleus, and the axon, a long fiber that carries the nerve impulse away from the cell body to the next neuron.
What is the part of the neuron that carries impulses toward the cell body?
The part of the neuron that carries impulses towards the cell body is called the dendrite.
List the Basic steps of simple reflex arc like the stretch reflex?
receptor: initiate impulse: receive something sensory neuron: will carry impulse from receptors to the central nervous system motor neuron: tranmits impulse away from central nervous system into effector internuncial neuron: carry impulse from pre- synaptic to post synaptic effector: muscles or glands
