Why is it helpful to have impulses to move only in one direction in a neuron?

Your neurons are adapted in such a way that impulses move only in one direction.

∙ 12y agoThis is helpful so that your body can respond to its surroundings in time to avoid possible injuries. If the impulses moved in both directions, it might take more time for the proper response to occur, and result in injury.

∙ 12y agoNerve impulses or "action potentials" move only in one direction within the body. This is called "orthodromic conduction". In the laboratory, where nerve cells can be isolated, action potentials can be made to artificially travel in the opposite direction. This is called "antidromic conduction".
Antidromic conduction would not be useful in our bodies. Imagine a sensory pathway. It begins in the skin with a touch receptor of some type, the information then travels through three other neurones at least, to get to the cerebral cortex (brain). If the information travelled backwards, back to the skin, it would be of no use. The touch receptor which initiated the signal can do nothing with this information. The only reason your perceive touch, or any other stimulus is because the information has reached the brain.
Furthermore, if your nerve cells did allow the information to travel in both directions, it would probably cause a reverberation of some type in the pathway. Thus in a motor pathway, you might be unable to suppress a voluntary movement once it is initiated.

In a neuron impulses move?
In a neuron, impulses move from dendrite to axon. These impulses carry energy to different parts of the neuron.
What are motor neuron diseases?
Motor neuron diseases are a group of progressive disorders involving the nerve cells responsible for carrying impulses that instruct the muscles in the upper and lower body to move
What regulates the body through impulses that come from the environment?
Sensory neurons provide information from the environment to the body. For example, when you touch a hot surface, a sensory neuron informs your body that the temperature near your skin is rising. Motor neurons are the neurons the body uses to react to the environment. For example, if you touch a hot surface, then your body will make your hand move away from that surface by a motor neuron. The action is the result of the motor neurons not the fact you realize it is hot, Motor neurons also send impulses to your muscles. These neurons are called somatic neurons. Another motor neuron is the autonomic neuron. This neuron control your organs and heart. Usually the Vegas nerve controls and divides this power in two ways: sympathetic and parasympathetic
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
What is the difference between reLAy neuron and motor neuron?
Motor nerves tell muscles to contract, thereby making you move.
Why is it helpful to have impulses moving only in one direction in a neuron?
Your neurons are adapted in such a way that impulses move only in one direction.
Why is it helpful to have impulses move only in one direction in a neuron-?
Nerve impulses travel one direction because of the action potential which is created because of Na+ and when K+ returns to normal.
In a neuron impulses move?
In a neuron, impulses move from dendrite to axon. These impulses carry energy to different parts of the neuron.
How do impulses move in response to a stimulus?
to the brain, then to the effector through the motor neuron
What neuron moves the impulses to the brain?
The brain is the control, and the whole reaction of a reflex arc starts with a stimulus, ie, touching a hot flame, the detector of this stimulus being the receptor. The electrical impulses travel through the sensory neuron to which it is then carried to the synapse (impulses reach the brain) the energy is then transferred across the synapse, to the relay neuron and then to the motor neuron, finally reaching the effector, (mainly muscle or gland) to move away the body part.
What are motor neuron diseases?
Motor neuron diseases are a group of progressive disorders involving the nerve cells responsible for carrying impulses that instruct the muscles in the upper and lower body to move
What is the structure of a neuron and what kinds of neurons are found in the body?
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 connective tissue, something like a package of uncooked spaghetti wrapped in cellophane. A bundle of nerve fibers is called a nerve.
How do impulses move?
by neurons
What is the difference between a sensory neuron and a motor neuron?
motor neuron=A neuron that conveys impulses from the central nervous system to a muscle, gland, or other effector tissue. sensory neuron= nerves that take in information from either the outside or from within the body.Sensory neurons receive impulses from your eyes, ears, tongue, nose and skin.Motor areas control your muscle during movement.andA sensory neuron is a nerve cell that transmits impulses to the central nervous system (spinal cord or brain). It is information such as taste, touch, hot, cold, sound, sight or pain. It's cell body is located just outside the central nervous system and has a very short axon which leads into the nervous system. A motor neuron is a nerve cell that transmits direction to muscles and organs from the central nervous system to perform some function. The motor neurones cell body is located in the central nervous system and has a long axon (longest in body is around 1m) This is how these two are different.hop
What steps involved in transmitting the impulse from one neuron to another and then to the muscle fiber?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineEach nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
What are impulses that are sent down a neuron?
These impulses are called Nerve impulse. Nerve impulse is wave of electrochemical change tha travels along the length of neuron. Electrical potentail of neuron when it is in unstimulated condition is -70 millivolts. In this state outside the membrane of neuron, concentration of positive ions is more than the inside of membrane. Inside the membrane potassium ions are more than sodium ions while outside the membrane sodium ions are more than the potassium ions present there. This balance is maintained by sodium-potassium pumps through which three sodium ions move outside and two potassium ions move inside the membrane at a time. During this activity ATPase (enzyme) breaks down the ATP into ADP and phosphate then energy is released. When a neuron is stimulated, stimulus causes its membrane to depolirized (sodium ions move inside and potassium ions move outside the membrane). The adjacent parts of membrane are also affected by this depolarization. The change travels along the neuron while the prior parts of membrane return to their original state.
