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?
The term 'motor neuron' is usually restricted to the efferent neurons that actually innervate muscles (the lower motor neurons). A single motor neuron may innervate many muscle fibres and a muscle fibre can undergo many action potentials in the time taken for a single muscle twitch.he interface between a motor neuron and muscle fiber is a specialized synapse called the neuromuscular junction. Upon adequate stimulation, the motor neuron releases a flood of neurotransmitters that bind to postsynaptic receptors and triggers a response in the muscle fiber which leads to muscle movement.
