The point of contact between the nerve and the muscle fibers it stimulates is called a?
neuromuscular junction
What site where the motor neuron and muscle cell meet is called the?
Neuromuscular junction
The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine
What travels from your brain to your skeletal muscle cells when you move?
When you decide to move, an electrical signal called an action potential is generated in your brain. This signal travels along your neurons and reaches the skeletal muscle cells via motor neurons. At the neuromuscular junction, a chemical called acetylcholine is released, which stimulates the muscle fibers to contract and initiate movement.
What prevents acetylcholine from accumulating in the neuromuscular junction?
The presence of an enzyme called acetylcholinesterasethat degrades acetylcholine is what prevents an accumulation of the neurotransmitter and sustained muscle contraction. Acetylcholinesterase is an enzyme that can be found within the neuromuscular junction. Thus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.
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.
What is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction
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 point of contact between the nerve and the muscle fibers it stimulates is called a?
neuromuscular junction
What do motor neurons attach to?
neuromuscular junction
What site where the motor neuron and muscle cell meet is called the?
Neuromuscular junction
The actual gap between an axon ending and the muscle cell is called what?
Neuromuscular junction.
Gap between axon terminal and muscle cell?
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.
The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine
The junction between a motor neurons axon and the muscle cell membrane is called?
neuromuscular junction or myoneural junction
Name the site of close juxtaposition of an end terminal and the sarcolemma of a muscle cell?
It is called the neuromuscular junction.
What is a sustained muscle contraction?
Occurs when acetylcholine (ACh) accumulates in the neuromuscular junction. It is called a tetanic contraction.
