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?
When an action potential reaches the end of a neuron, the acetylcholine is released and a new action potential begins in the muscle tissue. Nerves connecting to muscles are called motor neurons. Each neuromuscular junction is connected to a bundle of muscle fibers. A motor neuron may branch several times and connect to several bundles. All of these bundles will contract together upon getting a signal from the motor neuron. View the animation below, then complete the quiz to test your knowledge of the concept.
