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.

What is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction
Why is ''botox'' an effective anti-wrinkle treatment.describe its mechanism of action with reference to the neuromuscular junction?
"Botox" is actually a poison. It prevents muscle movement by preventing the nerve impulse to travel from the neuron across the neuromuscular junction and prevents the muscle from contracting. It is the toxin produced by the microbe that causes botulism.
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.
What does ach do at a neuromuscular junction?
ACh (acetylcholine) binds to receptors at the NMJ (neuromuscular junction) to induce contraction of muscle.
The junction between a motor neurons axon and the muscle cell membrane is called a neuromuscular junction or a?
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
The muscle-nerve interaction site?
Neuromuscular Junction
What position on the muscle cell where the nerve fibers connect?
The term for the connection between a muscle cell and a neuron is the neuromuscular junction.
Type of junction where a motor neuron and a skeleton muscle cell have contact?
A neuromuscular junction.
When a muscle contracts and relax it is called?
Spasm
What does the neuromuscular junction connect to?
The nervous system and the muscular system are connected by the neuromuscular junction. The connection is done with synapses between nerve and muscle fibers.
The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
What is the point of contact between a motor neuron and a skeletal muscle cell called?
This point is often called the neuromuscular junction or motor end plate. ?The neurotransmitter used here is acetylcholine.Many diseases occur with dysfunction at this junction, like Myesthenia Gravis, botulism, or Lambert Eaton Myasthenic Syndrome.
