Skeletal muscles normally work in pairs to perform movement and have 2 points of attachment. The point of origin is:

where the muscle attaches to the bone at a non-moving point

Muscles maintain posture by sustaining a certain amount of contraction and resistance. This is called:

muscle tone
flexion
contractibility
resilience

When muscles are not used they become smaller and weaker. This is termed:

immobility
muscle tone
hypotension
atrophy

glucose
myosin
actin

sodium
iron
calcium
potassium

Which of the following statements is false?

isometric and isotonic contractions cannot occur simultaneously
when a muscle contracts concentrically, it shortens
when a muscle contracts eccentrically it stretches
when a muscle performs an isometric contraction, it does not move a joint

If damaged, muscles heal more quickly than tendons because:

muscle tissue is softer than tendons
muscle tissue is more richly supplied with blood vessels
tendons attach to bone
tendons have fewer fibres

After vigorous exercise or prolonged tension, muscle fatigue can occur. Which of the following does NOT play a part in this condition?

a lack of oxygen
a build up of lactic acid
exhaustion of energy supply
insufficient pyruvic acid

What function do ligaments have?

to attach bones to each other
to attach muscle to bone
to attach muscles to each other
to attach a muscle to a joint

Which of the following statements is false?

the amount of oxygen if the blood is increased during exercise
an exercising muscle can receive up to 25 times its normal blood flow
as the muscle contractions compress the veins, so the return of venus blood to the heart is increased
the intestines and skin receive less blood during exercise

Muscle pain is termed:

myoma
myotonia
myalgia
myositis

Which of the following statements is true?

cramp is a sudden involuntary, painful muscle contraction
cramp can be caused by a lack of salt, water or minerals
a spasm is caused by a lack of oxygen, glucose and nutrients
all of the above

Which of the following statements is false?

insufficient oxygen during exercise can result in an accumulation of lactic acid
breathing is deepened and quickened if there is a presence of lactic acid
breathing returns to normal immediately after exercise has ceased
large amounts of oxygen are needed for the muscles and liver to dispose of lactic acid

A sprain is identified as:

a torn muscle
an overstretched or torn ligament
an inflammation of a tendon

triangular is
buccinators
mentalis

The zygomaticus is used when we:

grin
blow
laugh
pout

infraspinatus
supraspinatus
teres minor

rhomboids
deltoid
trapezius
supraspinatus

Which of the following muscles does not move the thumb?

abductor pollicis brevis
