A folded region of the sarcolemma at the neuromuscular junction?
The folded region of the sarcolemma at the neuromuscular junction is called the motor end plate. It is responsible for receiving signals from the motor neuron and initiating muscle contraction. The motor end plate is rich in acetylcholine receptors, which play a key role in neurotransmission at the 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.
At the neuromuscular junction the muscle fiber membrane is folded to form?
motor end plate
Synapse formed between the axon terminals of a motor neuron and the motor end plate of a muscle fiber?
Neuromuscular Junction
Describe the components of the neuromuscular junction?
The neuromuscular junction consists of the motor neuron terminal, synaptic cleft, and motor end plate on the muscle fiber. When an action potential reaches the motor neuron terminal, it triggers the release of acetylcholine into the synaptic cleft. Acetylcholine then binds to receptors on the motor end plate, leading to muscle contraction.
The a synaptic knob b motor end plate c neuromuscular junction d synaptic cleft e transverse tubule contains vesicles filled with acetylcholine?
c) neuromuscular junction, d) synaptic cleft.
What is the name of the point at which motor neuron synapses motor end plate?
The point at which a motor neuron synapses with a muscle fiber's motor end plate is called the neuromuscular junction. This is where the nerve impulse is transmitted from the motor neuron to the muscle fiber, leading to muscle contraction.
What potential motor end plate to synapse to acetylcholine synaptic cleft to special receptors on the skeletal muscle to action potential across the muscle travels down t-tubule to the what?
This is the neuromuscular junction. The action potential travels down the presynaptic motor neuron, releasing acetylcholine (ACh), which cross the synapse (neuromuscular junction), to bind to receptors on the end plate of muscle fibers, which induces depolarization, causing the muscle to contract.
Motor end plate is?
Motor end plate is a specialized area on a muscle fiber that forms a neuromuscular junction with a motor neuron. It is where the nerve impulse from the motor neuron triggers the muscle fiber to contract. The motor end plate is crucial for muscle function and movement.
Is curare poisoning affected by the motor end plate or the axon terminal?
Curare poisoning affects the motor end plate. Curare blocks nicotinic acetylcholine receptors on muscle cells at the neuromuscular junction, preventing the binding of acetylcholine and leading to muscle paralysis.
How does a neuromuscular blocking agent such as metubine interfere with muscle contraction?
Metubine works by blocking the transmission of nerve impulses at the neuromuscular junction, specifically at the nicotinic acetylcholine receptors. This prevents the muscle from receiving signals to contract, leading to muscle paralysis.
What is the function of motor end plate?
A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.
