List the cellular structures over which an impulse would pass?
In the body, an electrical impulse travels through the neurons, or nerve cells, to send signals to and from the brain. The Dendrites of the neuron accept the impulse, send it through the soma, down the axon, and to the axon terminal, where it'll be sent to the next neuron, almost instantly.
What travels through the neuron?
An electrical impulse will travel through a neuron.
What electrical impulse travels outward from the cell body along what?
Typically, the electrical signal that travels from the dendrites across the cell body travels by cable conduction properties (like cable TV). Once the signal reaches the axon hillock, which is the spot where the axon branches off the cell body, the electrical signal starts traveling by action potentials (and maybe some cable conduction). The signal travels to the terminal end of the axon where it initiates a calcium influx, which in turn initiates a release of neurotransmitter to act on the next, post-synaptic neuron. The axon is the long process (arm) that extends from the first cell body to the next neuron.
State the three main parts of a neuron and describe how an impulse travels through a neuron?
Okay, information is received through the dendrites, and then moves on the the cell body. From there, the cell's axon passes the message on to other neurons or to muscles or glands.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What is the path of an electrical impulse as it moves through a neuron?
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
How is an impulse communicated from nerve cell to nerve cell?
Via chemical messangers that cross the synapse.

What muscles are used when you do step ups?
Various muscles of lower limb and back and hip.Each 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.
What travels through the neuron?
An electrical impulse will travel through a neuron.
What direction does nerve impulse travel?
Along a nerve cell, the impulse travels from the axon to the dendrites and then again to the axons through the synapse.
What electrical current flows through electrical home devices?
The electrical current for a home device travels in a circuit.
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

How does an impulse cross a synape?
An electrical impulse travels along a nerve until it hits a synapse, where it causes the release of chemicals (neurotransmitters) which migrate across the synapse. At the other side , these neurotransmitters activate receptors which cause an electrical signal to continue along the nerve.
What is a form of energy that travels from a battery?
chemical energy
