Anatomy & Physiology of Muscle Spindles

The video tutorial explains the roles of muscle spindles and Golgi tendon organs in muscle function and exercise. It covers the location and function of these sensory receptors, highlighting how Golgi tendon organs sense muscle force to prevent injury, while muscle spindles detect muscle stretch to maintain proprioception and prevent overstretching. The tutorial also details the reflex arcs involving these receptors, such as the patellar knee jerk reflex, and discusses how voluntary control can override these reflexes during exercise, potentially leading to muscle tears.
