A&R both true, but R is not correct explanation of A
A is true but R is false
both A&R are false
A - muscle contraction force increases with rise in strength of stimulus
R - this is due to increased contraction of individual muscle fibres with increase in stimulus strength
A&R both true, R is correct explanation of A
both A&R are false
A&R both true, but R is not correct explanation of A
A is true but R is false
A - fatigue is inability of muscles to relax
R - this is due to the fact that they contract and relax as a unit
A&R both true, R is correct explanation of A
A&R both true, but R is not correct explanation of A
A is true but R is false
both A&R are false
A - the phase of muscle contraction occurs when myosin binds and releases actin
R - muscle contraction is initiated by a signal sent by the PNS via motor neuron

R - this bone is commonly called the collar bone
both A&R are false
A&R both true, R is correct explanation of A
A&R both true, but R is not correct explanation of A
A is true but R is false
A - there are 12 pairs of ribs
R - each rib is a thin flat bone connected dorsally to vertebral column and ventrally to sternum
A is true but R is false
A&R both true, R is correct explanation of A
A&R both true, but R is not correct explanation of A
both A&R are false
A - joints are point of contact between bones or between bones and cartilages
R - force generated by the muscles is used to carry out movement through joints, where the joints act as a fulcrum
both A&R are false
A is true but R is false
A&R both true, but R is not correct explanation of A
A&R both true, R is correct explanation of A
A - myasthenia gravis is an autoimmune disorder affecting neuromuscular junction
R - it leads to fatigue, weakening and paralysis of voluntary muscles
A&R both true, R is correct explanation of A
A&R both true, but R is not correct explanation of A
A is true but R is false
both A&R are false
A - cardiac muscles are involuntary in nature
R - nervous system does not control their activities directly
both A&R are false
A is true but R is false

A&R both true, but R is not correct explanation of A
A is true but R is false
both A&R are false
A - joints are essential for all types of movements involving the bony part of the body
