Twitch, Summation, Incomplete (Unfused) Tetany, & Complete (Fused) Tetany Complete Contraction! Complete Relaxation! A little bit of relaxation before next contraction. No relaxation at all before next contraction.

Fatigue & Stretching of Muscle As a muscle stretches, contraction is stronger because there is a more favorable (optimal) overload between actin and myosin Nerve & Muscle Fatigue occurs fastest in nerve and muscle combo Run out of ACH Muscle ONLY

Strychnine Injection and Curarune Injection STRYCHNINE causes convulsions in skeletal muscle by causing nerve to release more ACH CURARINE causes paralysis in skeletal muscle by blocking effects of ACH

Brachioradialis vs. Palmoris Longus Brachioradialis Little electrical activity. Not very active. Palmoris Longus Lots of electrical activity. Very active.

Tibialis Anterior vs. Gastrocnemius Standing Still have good balance NOT VERY ACTIVE Standing on one foot balance not as good MORE ACTIVE! Standing on one foot with eyes closed balance not good at all muscle much more active as you lack visual input VERY ACTIVE!!

Tibialis Anterior vs. Gastrocnemius Tibialis Anterior Lean Backward Tibialis anterior more active as it tries to pull you back upright by pulling you forward Lean Forward Gastrocnemius more active as it tries to pull you back upright by pulling you backward Gastrocnemius
