all options
Tendons connect
bone to bone
muscle to bone

all options
A motor unit is:
a motor neuron
a group of muscle fibres
the contraction of muscle
a motor neuron and all the muscle fibres it activates
The force of muscular contraction can be increased by:
frequency of activation
recruitment of larger motor units
none of these
both of these
Which of the following is not a function of the muscular system?
protection of vital organs
maintaining posture
thermogenisis
movement
The name of the basic unit responsible for muscular contraction is:
myofibrils
myofilaments
muscle fibre
sarcomere
Pick the correct option describing the effect of muscle contraction on the structure of a sarcomere
A Band unchanged, I Band unchanged, H Zone disappears
A Band shortens, I Band unchanged, H zone unchanged
A Band unchanged, I Band shortens, H Zone disappears
Skeletal muscles operate via Reciprocal Inhibition pick the correct actions
Agonist contract, Antagonist contract
Agonist contract, Antagonist relax
Agonist relax, Antagonist contract
Agonist relax, Antagonist realx Agonist relax, Antagonist realx
Which of the following is not a type of muscular contraction?
concentric
exocentric
isometric
isokinetic
The humerus articulates with the radius & ulna to form a:
saddle joint
pivot joint
gliding joint
hinge joint
the muscle responsible for shrugging the shoulders is the:
trapezius
latissimus dorsi
rhomboids
pectoralis major
which of these muscle fibre arrangements allow for the greatest strength?
fusiform
pennate
skeletal
smooth
Whilst carrying a tray in front of the body with the hands lying flat under the tray:
the hands are flexed
the hands are extended
the hands are supinated
the hands are pronated
The all or nothing principle states that:
all muscle fibres of a motor unit will contract whenever an electrical impulse is received
the strength of the electrical impulse will determine the number of muscle fibres that contract in a motor unit
when the electrical impulse reaches a certain threshold, all the fibres of that motor unit will contract at the same time as forcefully as possible
all the muscle fibres in a muscle must contract in order for the muscle to contract and create movement
Pennate muscle fibre arrangements are able to generate greater forces because they have:
high fibre length to muscle length ratio
low fibre length to muscle length ratio
more fibres packed into the same area compared to fusiform muscles
less fibres packed into the same area compared to fusiform muslces
The advantage of fusiform muscles over pennate muscles is they:
connect to bones via stronger tendons
generate greater force
have long muscle fibres
generate greater contractile velocities
As the speed of contraction increases, the amount of force a muscle can generate proportionately decreases
True
False
Fast-twitch fibres cannot become slow-twitch fibres, but some fast-twitch fibres can take onslow-twitch fibre characteristics after aerobic and endurance training.
True
False
Which of the following combination of characteristics allow slow-twitch fibres to be suited to endurance type events:
high fatigue resistance; low mitochondria density; low capillary density
high fatigue resistance; high mitochondria density; high capillary density
low fatigue resistance; high mitochondria density; low capillary density
low fatigue resistance; low mitochondria density; high capillary density
