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.
What are the receptors called that are found on the end of the motor end plate?
The receptors found on the end of the motor end plate are called nicotinic acetylcholine receptors. These receptors respond to the neurotransmitter acetylcholine released from the motor neuron and play a crucial role in initiating muscle contraction.
What is the neurotransmitter released at the motor end plate?
Acetylcholine is the primary neurotransmitter released at the motor end plate, where it binds to receptors on muscle cells to initiate muscle contraction.
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.
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.
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.
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.
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 motor neuron form a synapse with a muscle cell?

A motor neuron and all the muscle cells that it stimulates are referred to as a motor end plate?
false, it would be a motor unit.
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.
A deficiency of ACh receptors in a motor end plate would cause and is called?
A deficiency of ACh receptors in a motor end plate would cause muscle weakness or paralysis. This condition is called myasthenia gravis.
Synapse formed between the axon terminals of a motor neuron and the motor end plate of a muscle fiber?
Neuromuscular Junction
What happens to the muscle membrane when acetylcholine binds to receptors at the motor plate?
When acetylcholine binds to receptors at the motor plate, it triggers the opening of ion channels in the muscle membrane. This allows sodium ions to flow into the muscle cell, leading to depolarization of the membrane and initiation of a muscle action potential. Subsequently, this action potential travels along the muscle cell membrane, leading to muscle contraction.
