Question

Quizplus · Accepted Answer

Motor neurons are the nerve cells responsible for transmitting messages from the brain and spinal cord to the muscles to initiate movement. They signal muscles to either contract or relax through the release of neurotransmitters at the neuromuscular junction. Sensory neurons, on the other hand, transmit information from the sensory organs to the brain and spinal cord for processing, while interneurons facilitate communication between different neurons. Glial cells provide support and protection to neurons, but they do not directly signal muscles to relax or contract.
