alpha motor neurons
Alpha motor neurons are specialized nerve cells located in the spinal cord that play a crucial role in controlling voluntary muscle movements. They transmit signals from the central nervous system to skeletal muscles, causing them to contract and produce movement. These neurons are essential for activities such as walking, running, and lifting objects.
Each alpha motor neuron can connect to multiple muscle fibers, forming a motor unit. When an alpha motor neuron is activated, it sends an electrical impulse that triggers the muscle fibers to contract simultaneously. This coordinated action allows for smooth and controlled movements of the body.
