Nerve impulses travel one direction because of the action potential which is created because of Na+ and when K+ returns to normal.
Your neurons are adapted in such a way that impulses move only in one direction.
yes
Your brain sends electrical impulses to your muscles that cause them to contract and relax causing your limbs to bend and straighten. And it does it 10 times faster than you can blink.

Liam, but I don't think he moved schools that many times.
Your neurons are adapted in such a way that impulses move only in one direction.
In a neuron, impulses move from dendrite to axon. These impulses carry energy to different parts of the neuron.
to the brain, then to the effector through the motor neuron
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.
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
Your neurons are adapted in such a way that impulses move only in one direction.
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.
by neurons
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
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
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.
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
