Quizplus · Accepted Answer

The point where a motor neuron meets a muscle fiber is called the neuromuscular junction. This is where the neurotransmitter acetylcholine is released to stimulate the muscle fiber to contract. The dorsal horn is a region of the spinal cord involved in sensory processing, while the end terminus and ventral root are not related to the connection between a motor neuron and muscle fiber.
