A MRI scan is usually ordered to better visualize the damage to each of the components of the PLC and also to assess the status of the meniscus and articular cartilage of the knee. In certain cases where the PLC suffers a âsprainâ or a minor tear the injury may be able to be treated with non-operative measures.
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneural junction?
One motor neuron (nerve cell) may stimulate a few muscle cells or hundreds of them, depending on the. particular muscle and the work it does. One neuron and all the skeletal muscle cells it stimulates are a. motor unit. When a long threadlike extension of the neuron, called the nerve fiber or axon, reaches the. muscle, it branches into a number of axon terminals, each of which forms junctions with the. sarcolemma of a different muscle cell. These junctions are called neuromuscular (literally, ânerve-. muscleâ) junctions.
