Muscular System Flashcards
(19 cards)
Name the major muscles (11)
Deltoid, pectoral, biceps, abdominal, quadriceps, trapezius, latissimus dorsi, triceps, gluteals, hamstrings, gastrocnemius
What movement does the deltoid produce?
Abducts, flexes and extends the shoulder
What movement do the pectorals produce?
Abducts the shoulder
What movement do the biceps produce?
Flexes the elbow
What movement do the abdominals produce?
Flex the trunk
What movement do the quadriceps produce?
Extends the knee
What movement do the triceps produce?
Extends the elbow
What movement do the gluteals (gluteus maximum) produce?
Extends the leg at the hip
What movement do the hamstrings produce?
Flexes the knee
What movement does the gastrocnemius produce?
Point the toes
What is the role of antagonistic pair in muscle movement?
2 muscles that work together to produce movement
What is the role of agonist in muscle movement?
The muscle that contracts and shortens to make the movement happen
What is the role of antagonist in muscle movement?
The muscle that relaxes and lengthens to allow the movement to happen
What is the role of fixator in muscle movement?
A muscle that holds a joint in place to support a movement at a different joint
Give examples of antagonistic pairs
Hamstring and quadriceps
Biceps and triceps
Explain the antagonistic pair when you flex your elbow
The bicep is the agonist and the tricep is the antagonist
Explain the antagonistic pair when you flex your knee
The hamstrings are the agonist
The quadriceps is the antagonist
Short term effects of exercise on muscular system
What happens whilst we are exercising
Increased muscle temperature
Lactic acid production
Fatigue
Long term effects of exercise on the muscular system
The adaptations our body makes as a result of regular training
Hypertrophy (muscles get bigger and stronger) Increased muscular strength Increased muscular endurance Increased resistance to fatigue Increased capillarisation to muscles
