CHAPTER 7 ICTC
MUSCULAR SYSTEM
| Question | Answer |
|---|---|
| How many muscles is in the muscular system? | over 600 |
| WHAT IS THE PRIMARY FUNCTION OF THE MUSCULAR SYSTEM? | MOVEMENT |
| NAME ANOTHER FUNCTION OF THE MUSCULAR SYSTEM NOT MOVEMENT. | PRODUCES HEAT |
| MUSCULAR SYSTEM IS SPECIALIZED FOR WHAT? | CONTRACTION |
| NAME THREE THINGS MUSCLES CAN DO. | PULL,SHORTEN AND CONTRACT |
| NAME THE FOUR ORGAN SYSTEMS INVOLVED IN MOVEMENT. | MUSCULAR, SKELETAL, NERVOUS,AND RESPIRATORY |
| WHAT DOES THE MUSCULAR ORGAN SYSTEM DO? | IT MOVES THE BONES |
| WHAT DOES THE SKELETAL ORGAN SYSTEM DO? | BONES ARE MOVED, AT JOINTS BY MUSCLES |
| WHAT DOES THE NERVOUS ORGAN SYSTEM DO? | IMPULSES TO MUSCLE CAUSE CONTRACTION |
| WHAT DOES THE RESPIRATORY ORGAN SYSTEM DO? | EXCHANGES O2 AND CO2 BETWEEN AIR AND BLOOD |
| MUSCLE TISSUE-SKELETAL IS VOLUNTARY AND ? | STRIATED |
| MUSCLE TISSUE-SKELETAL IS MULTI NUCLEATED AND ? | CYLINDRICAL |
| MUSCLE TISSUE -SKELETAL IS CAPABLE OF SUDDEN, POWERFUL CONTRACTIONS, READILY SUBJECT TO FATIGUE CANNOT SUSTAIN WHAT? | CONTRACTION FOR LONG PERIODS OF TIME |
| MUSCLE TISSUE-SKELETAL IS MADE OF? | SEVERAL FIBERS |
| MUSCLE TISSUE-SMOOTH IS VISCERAL AND ? | INVOLUNTARY |
| MUSCLE TISSUE -SMOOTH IS SPINDLE SHAPED ONE NUCLEUS AND ? | NON STRIATED |
| MUSCLE TISSUE -SMOOTH IS FOUND WHERE? | IN WALLS OF HOLLOW OR TUBULAR STRUCTURES |
| MUSCLE TISSUE-SMOOTH IS RESPONSIBLE FOR WHAT? | SLOWER SUSTAINED CONTRACTION |
| MUSCLE TISSUE -SMOOTH CAN REMAIN IN STATE OF CONTRACTION FOR LONG PERIODS OF TIME, SUSTAINED RHYTHMIC CONTRACTIONS AND WHAT? | SELF EXCITING |
| EACH SKELETAL MUSCLE IS COMPOSED OF WHAT? | THOUSANDS OF MUSCLE FIBERS (CELLS) |
| TENDONS CONNECT MUSCLES TO BONES AND MERGE WITH ? | FASCIA |
| WHAT IS THE FASCIA? | COVERS MUSCLE AND IS CONTINOUS WITH THE PERIOSTEUM OF THE BONES(MERGERS WITH TENDONS |
| HOW MANY POINTS IS EACH MUSCLE ATTACHED TO? | AT LEAST 2 POINTS |
| NAME THE POINTS EACH MUSCLE IS ATTACHED TO. | ORIGIN AND INSERTION |
| THE IMMOBILE POINT OF ATTACHMENT OR STATIONARY END IS THE | ORIGIN |
| THE MOVEABLE POINT OF ATTACHMENT IS ? | INSERTION |
| WHAT IS THE NAME OF THE CENTER OR LARGEST PART OF A MUSCLE? | BODY OR BELLY |
| HOW DO MUSCLES BRING ABOUT MOVEMENT? | BY WORKING IN PAIRS OR GROUPS |
| PRIME MOVERS ARE? | THOSE MUSCLES THAT INITIATE MOVEMENT;ARE RESPONSIBLE FOR MOST OF THE MOVEMENT |
| DEFINE ANTAGONISTS: | MUSCLES THAT OPPOSE THE ACTION OF THE PRIME MOVER AND MUST BE RELAXED SO THAT MOVEMENT MAY TAKE PLACE |
| DEFINE SYNERGIST: | MUSCLES WITH THE SAME FUNCTION, OR THAT WORK TOGETHER TO PERFORM A PARTICULAR FUNCTION |
| HOW DO MUSCLES ATTACH TO BONES? | THROUGH EITHER TENDINOUS OR FLESHY ATTACHMENTS |
| MUSCLES HAVE AT LEAST TWO ATTACHMENTS AND MUST CROSEE AT LEAST HOW MANY JOINTS? | ONE |
| WHAT CAN AFFECT THE SHAPES OF BONES? | MUSCLES |
| MUSCLES ALWAYS PULL AND GET? | SHORTER |
| MOVEMENT THAT DECREASES THE ANGLE OF VENTRAL SURFACES ARE KNOWN AS ? | FLEXION |
| MUSCLES THAT DECREASE THE ANGLE ARE KNOWN AS? | FLEXORS |
| MUSCLES WORK IN ? PAIRS | OPPOSING |
| WHAT DO MUSCLE STRIATIONS/ FIBER DIRECTION DO? | POINT TO ATTACHMENTS AND SHOW DIRECTION OF PULL |
| WHERE DO NERVE IMPULSES FOR MOVEMENT COME FROM? | THE FRONTAL LOBES OF THE CEREBRUM |
| COORDINATION OF MEOVEMENT IS CONTROLLED BY ? | THE CEREBELLUM |
| WHAT IS MUSCLE TONE? | THE STATE OF SLIGHT CONTRACTION OF MUSCLES |
| MUSCLE TONE HELPS TO MAINTAIN WHAT? | UPRIGHT POSTURE AND IS THE ABILITY OF THE MUSCLE TO MAINTAIN A CONTRACTION |
| MUSCLES REQUIRE WHAT TO CONTRACT? | ATP |
| CELLULAR RESPIRATION PRODUCES WHAT? | WATER,CARBON DIOXIDE, AND ATP |
| NAME THE TWO GENERAL TYPES OF EXERCISE? | ISOTONIC AND ISOMETRIC |
| ISOTONIC EXERCISE DOES WHAT? | CONTRACT BRING ABOUT MOVEMENT |
| WHAT DOES ISOMETRIC EXERCISE DO? | CONTRACT WITHOUT MOVEMENT |
| DEFINE PROPRIOCEPTION: | THE BRAIN'S ABILITY TO KNOW WHERE MUSCLES ARE AND WHAT THEY ARE DOING WITHOUT LOOKING AT THEM |
| DEFINE STRETCH RECEPTORS: | SEND INFORMATION TO THE PARIETAL LOBES OF THE CEREBRUM GENERAL FUNCTION IS TO DETECT CHANGE, GIVE BRAIN MENTAL PICTURE OF WHERE THE MUSCLE IS |
| NAME 3 ENERGY SOURCES FOR MUSCLE CONTRACTION. | ATP,CREATINE PHOPHATE,GLYCOGEN |
| WHAT IS THE MOST ABUNDANT ENERGY SOURCE IN MUSCLE FIBERS? | GLYCOGEN |
| IF O2 IS NOT PRESENT WHAT IS GLUCOSE CONVERTED TO AND WHY? | LACTIC ACID, BECAUSE IT CANNOT BE COMPLETELY BROKEN DOWN. |
| WHAT DOES HEMOGLOBIN DO? | DELIVERS O2 (RBC'S IN BLOOD) |
| WHAT DOES MYOGLOBIN DO? | (WITHIN MUSCLE FIBERS)STORES O2 |
| WHAT MINERAL MUST BE PRESENT FOR HEMOGLOBIN AND MYOGLOBIN? | IRON |
| OXYGEN STORED UP IN WHAT IS QUICKLY USED UP DURING STRENOUS EXERCISE? | MYOGLOBIN |
| GLUCOSE CONVERTS TO LACTIC ACID FOR ENERGY WHICH CAUSES WHAT? | MUSCLE FATIGUE |
| INA STATE OF FATIGUE MUSCLES CANNOT WHAT? | CONTRACT EFFICIENTLY AND CONTRACTON MAY BECOME PAINFUL |
| WHAT REMAINS HIGH TO RECOVER? | RESPIRATORY/HEART RATE |
| WHAT HELPS TO REMOVE EXCESS HEAT? | SWEATING |
| MOTOR NERVE ENDINGS(NUERONS) ARE FOUND WHERE? | ON EACH FIBER |
| WHAT IS A NUEROMUSCULAR JUNCTION? | WHERE MOTOR NUERON COMES IN CONTACT WITH MUSCLE FIRBER;AREA WHERE THE MOTOR NEURON TERMINATES ON THE MUSCLE FIBER |
| AXON TERMINAL (MOTOR END PLATE) ENLARGED TIP OF A MOTOR NEURON CONTAINS WHAT? | ACETYCHOLINE |
| WHAT IS SARCOLEMMA? | MEMBRANE OF THE MUSCLE FIBER; IT CONTAINS RECEPTOR SITES FOR ACETYLCHOLINE AND CHOLINESTERASE |
| WHAT IS SYNAPSE? | SMALL SPACE BETWEEN THE AXON TERMINAL AND THE MUSCLE FIBER |
| WHAT IS ACTIN AND MYOSIN? | PROTEINS IN MUSCLE FIBERS RESPONSIBLE FOR CONTRACTION AND RELAXATION MYOSIN IS THE CENTER OF THE SARCOMERE |
| WHAT IS THE FUNCTIONS OF TROPIN AND TROPOMYOSIN? | PREVENT THE SLIDING OG ACTIN AND MYOSIN WHEN THE MUSCLE FIBER IS RELAXED |
| WHAT IS SACROPLASMIC RETICULUM? | RESERVOIR FOR CALCIUM WHICH IS ESSENTIAL FOR THE CONTRACTION PROCESS |
