Muscle contraction results from an attachmentâdetachment cycle between the myosin heads extending from myosin filaments and the sites on actin filaments. The myosin head first attaches to actin together with the products of ATP hydrolysis, performs a power stroke associated with release of hydrolysis products, and detaches from actin upon binding with new ATP. The detached myosin head then hydrolyses ATP, and performs a recovery stroke to restore its initial position.
1 When you have one of those infected zits and you try to pop it but the pain is just too much to bear; it is sensory (afferent) neurons that are telling your brain about the pain.  Motor (sometimes called Efferent) Neurons: Motor (Efferent) neurons take information from the brain and send in out to the rest of the body. If you have your heart set on popping that zit, you use motor (efferent) neurons to move your fingers into the proper pinching to pop position.
