| WHY IS COMPARTMENT SYNDROME SERIOUS? | IT DEPRIVES THE MUSCLE OF O2 |
| WHAT CAUSES THE FORCE-GENERATING CROSSBRIDGES TO DO | THE BINDING OF THE MYOSIN HEAD TO ACTIN |
| WHAT FORM FORCE-GENERATING CROSSBRIDGES, SLIDING FILAMENTS, AND CONSIDERED CONTRACTILE PROTEINS? | ACTIN AND MYOSIN |
| WHAT OCCURS WHEN CALCIUM IS PUMPED BACK INTO THE SARCOPLASMIC RETICULUM? | MUSCLE RELAXATION |
| WHAT HAPPENS IF THE SOMATIC MOTOR NERVE THAT SUPPLIES THE MUSCLES OF THE THIGH, GETS SEVERED? | CANNOT WALK |
| CHARACTERIZED BY SKELETAL MUSCLE WEAKNESS | MYASTHENIA GRAVIS |
| INCREASES THE FORCE OF MUSCLE CONTRACTION | RECRUITMENT |
| WHAT DOES CURARE-INDUCED MUSCLE BLOCKADE AT THE Nm RECEPTORS CAUSE? | PARALYSIS |

| THE HEAD OF THIS CONTRACTILE PROTEIN BINDS TO ACTIN TO FORM A CROSSBRIDGE | MYOSIN |
| CALCIUM IS STORED WITHIN THIS MUSCLE STRUCTURE | SARCOPLASMIC RETICULUM |
| THE MUSCLE ATTACHMENT TO THE MOVABLE BONE | INSERTION |
| USE IT OR LOSE IT | ATROPHY |
| A HELPER MUSCLE | SYNERGIST |
| A MUSCLE OF MASTICATION | MASSETER |
| MAJOR MUSCLE OF THE ANTERIOR CHEST; ATTACHES TO THE HUMERUS | PECTORALIS MAJOR |
| THE MUSCLE GROUP THAT LIES ALONG THE POSTERIOR THIGH; FLEXES THE LEG AT THE KNEE | HAMSTRINGS |
| CONTRACTION OF THIS MUSCLE CAUSES PLANTAR FLEXION | GASTROCNEMIUS |
| THIS MUSCLE ATTACHES TO THE CALCANEUS BY THE ACHILLES TENDON | GASTROCNEMIUS |
| WHAT HAPPENS WHEN THE SKELETAL MUSCLE IS STIMULATED QUICKLY AND REPETITIVELY? | THE MUSCLE TETANIZES |
