WebMotor units are organized slightly differently in invertebrates; each muscle has few motor units (typically less than 10), and each muscle fiber is innervated by multiple neurons, including excitatory and inhibitory neurons. WebFeb 9, 2024 · Alpha motor neurons are relatively large motor neurons that innervate skeletal muscle and cause the muscle contractions that generate movement. Specifically, they innervate extrafusal muscle fibers, which are standard muscle fibers.
