What is the major muscle that raises the arm to the horizontal position shown in the image?
Trapezius
Pectoralis major
Deltoid
Latissimus dorsi
Name the type of muscle contraction required to hold the weight for a few seconds with the arms in the horizontal position on the right
Isointerial
Concentric
Eccentric
Isometric
Which of the following are voluntary muscles?
Smooth
Cardiac
Heart
Skeletal
Which of the following is an example of a convergent muscle arrangement?
Rectus Abdominis
Tricep Brachii
Pectoralis Major
Gastrocnemius
Which of the following is not true regarding pennate muscles?
Unipennate muscles have fibres running down one side of the tendon eg Gastrocnemius
Bipennate muscles have fibres running down three sides of a tendon eg Quadricep
Multipennate muscles have fibres branching out from several tendons eg Deltoid
Multipennate muscles enables the body to produce the most force
Which of the following muscles is fusiform?
Bicep
Gastrocnemius
Deltoid
Tibialis Anterior
Which of the following is true about the size principle?
Motor unit recruitment begins with large units to small units
Motor unit recruitment begins with small units to large units
Motor unit recruitment depends on the amount of force being produced
Motor unit recruitment recruits whatever is most excitable
Which of the following is incorrect about small motor units?
They are slow contracting
The are easily excitable
They are fatigue resistant
They are utilised for high force activities
Which of the following activities is best suited to recruiting large motor units?
A golf put
A netball chest press
A soccer goalkeeper's kick from the box to past half way
A dart throw
Which of the following is true about the all or nothing principle?
For the fibres of a motor unit to contract, the electrical impulse must reach a certain threshold, or the fibre will not contract
The threshold for any muscular contraction is the same
For the fibres of a motor unit to contract, most of the threshold needs to be met, or no movement will occur
Motor unit recruitment begins with small units to large units
Which of the following is correct about an agonist?
It is the muscle that relaxes in a contraction
It is the muscle that lengthens
It is the primary muscle responsible for movement
It is the tricep in a bicep curl
Reciprocal inhibition is a term used to explain...
How muscles work in teams - one contracts while the other relaxes
How muscles are always working to allow contractions to occur
How muscle contractions are eccentric and concentric
How muscles are recruited depending on how much force is being produced
Which is correct about the agonist and antagonist of a bench press during the upwards phase?
Agonist: latissimus dorsi, antagonist: pectoralis major
Agonist: pectoralis major, antagonist: latissimus dorsi
Agonist: pectroalis major, antagonist: deltoid
Agonist: deltoid, antagonist: pectoralis major
What is the type of muscle contraction occurring in the image?
Isoinertial
Isometric
Isokinetic
Concentric
