Muscle Spindles (Ans - sensory receptors in the muscles that are parallel to the muscle fibers and are sensitive to change in muscle length. Spindles stretch with muscle and sends information to CNS. helps to prevent muscles from stretching too far or too fast Golgi Tendon Organs (Ans - sensory receptors that are located at the point where the skeletal muscle fibers insert into the tendon. Sensitive to change in tension at the rate of change causes the muscle to relax Epimysium (Ans - connective tissue UNDER fascia that acts as an outer layer of the whole muscle Perimysium (Ans - connective tissue acts as an outer layer of fascicles Endomysium (Ans - between the individual muscle fibers Type 1 Muscle Fiber (Ans - "slow-twitch", smaller in size, lessforce produced, long-term contractions (stabilization) Type 2 Muscle Fiber (Ans - fast twitch, larger, quick to fatigue, force and power exercises Agonist (Ans - PRIME MOVER, main muscles ex: chest press-> pectoralis major
