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.
In which direction does a nerve impulse usually move?
It's called the ACTION POTENTIAL, or, in the case of a myelinated axon, SALTATORY CONDUCTION.
What part of the body does the brain tell to move your legs in order to pedal?
Motor Cortex
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
Can you define an impulse movement in dance?
An impulse move in dance is when the dancer "tweaks" his or her body suddenly. These movements look like sudden jerks or twitches.
What do motor cells do?
cause the body to move.
What part of the body tells the body what to do and how to move?
The frontal cortex (motor cortex) of the brain.
What do motor cell nerves do?
cause the body to move.
What do motor nerve cell's do?
cause the body to move.
How do your body parts move?
Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon.
How do bones muscles and joints work together to move the body and be flexible?
Skeletal muscles are controlled by nerves from the Peripheral Nervous System. This causes the muscles to contract when they receive the messages transmitted along motor neurons, originating in the motor areas of the cerebral cortex. The axons of these motor neurons extend out to the muscle where it divides and goes to different muscles. The motor pathways that carry the nerve impulse from brain to muscle are composed of two neurons: - Upper motor neurons --> (cell body in the brain) - Lower motor neurons --> (cell body in the grey matter of the spinal cord) When a nerve impulse initiates the contraction of a skeletal muscle, it results in movement about a joint. Hope this helped :)

What part of nervous system transmit message?
Impulses in the cell body (soma) of a neuron and move on along its axon, which conducts the impulse to a synapse at the end of the axon. There neurotransmitters are released into the synaptic cleft, so that the impulse can stop or go on to the next neuron or a gland/motor end plate, depending on the kind of neurotransmitter. Different types of neurotransmitters are: acetylcholine, adrenaline, noradrenaline, serotonine.
How does sensory impulse move throughout the body?
The nerve impulse travels through and reaches the threshold potential which opens Na+ Channels in the cell membrane. The Na+ ions diffuse into cell. The charges reverse at that point on the neuron, and which the cell becomes depolarized. Positive inside; negative outside. source: FM

Howdo muscles move in your body?
Muscles make possible every move we make, even when we are sleeping. Your muscles move according to what they are fromed. To be more specific, a muscle is made up of many bundles of muscle fibers. Each of these bundles of fibers is called a motor unit. Each unit has a motor nerve which branches out at its tip. Each muscle fiber, therefore, has its own nerve ending to stimulate it. An electrochemical impulse is transmitted by chemicals from the nerve ending to the fiber, causing the fiber in that motor unit to contract and this is how each muscle of your body moves.
