end-plate
Học thuậtThân thiện
The motor neuron's end-plate releases neurotransmitters onto the muscle fiber.
Definition
- Noun:
- A specialized structure at the neuromuscular junction: The "end-plate" is the flattened, disc-shaped terminal ending of a motor neuron's axon. It forms the synaptic connection with a muscle fiber and is the site where neural impulses are transmitted to initiate muscle contraction.
Examples of Usage
- Noun:
Advanced Usage
- "Motor end-plate": This is a more precise and commonly used term in neurophysiology, explicitly linking the structure to motor neurons.
Variants and Related Words
- End-plate potential (EPP): (noun) The local depolarization of the muscle cell membrane generated at the end-plate by the neurotransmitter.
- Neuromuscular junction: (noun) The entire synaptic connection between a motor neuron and a muscle fiber, which includes the end-plate.
Synonyms
- Motor end-plate: The most direct synonym in scientific contexts.
- Synaptic end bulb: A less common but related term describing the neuron's terminal structure.
Related Phrases
- End-plate noise: A specific pattern observed in electromyography (EMG) related to the activity at the end-plate.
