Brain send the message via nerve impulses involving neurons which use the neuro-transmitter Acetylcholine
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 has the function of transmitting a muscle impulse into the interior of the cell?
Transverse Tubules
What sends an impulse to a muscle or gland?
axon
What location does a neuron transfer an impulse to another cell?
It depends on what the next structure is. If it is another neurone, then it is a synapse. If it is skeletal muscle, then the it is a neuromuscular junction. If it is any other type of muscle, then it is a myoneural junction.
When a muscle contracts it does what?
In order for a muscle to contract, the brain sends a nerve impulse to the muscle it wants to contract. The nerve impulse triggers the potassium inside the muscle fiber cell to switch places with the calcium outside the cell wall, thereby feeding the cell and contracting the muscle. A second nerve impulse from the brain triggers the calcium to switch places with the potassium, releasing the contracted muscle.
What carries an impulse across a synapse to a muscle?
neurons?
What monitors muscle length and sends an impulse to the spinal cord to initiate the stretch reflex?
What monitors muscle length and sends an impulse to the spinal cord to indicate the stretch reflex
What happens to a muscle when an electrical impulse from a nerve stops?
yes
Does the impulse cross the neuromuscular junction when a muscle contracts?
No, the impulse traveling down the axon ends at the axon terminal but causes the axon terminal to release neurotransmitters. The neurotransmitters diffuse across the synaptic cleft causing the sarcolemma of the muscle to initiate its own impulse.
When a single neuron sends a strong enough impulse to a muscle that how many muscle fibers does it cause to contract?
This will depend upon the number of muscle fibers the nerve innervates. However, all fibers innervated by the nerve should contract in response to the neuronal impulse.
What is neurotransmitter and give examples?
A chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve, muscle, organ, or other tissue. A neurotransmitter is a messenger of neurologic information from one cell to another.
The impulse that triggers a contraction travels deep into a muscle fiber by means of what?
transverse tubules
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
