Skeletal Muscle quiz

what is the structure of a muscle cell?

what are the three phases of a contraction? Identify them on this table

the latent period generates no force but has chemical changes (release of ____ from ____) in preparation for contraction. time between generation of ____ and muscle ____

the contraction phase is from latent period and ends when

the relaxation phase is from peak tension until the end of

what are the four types of tension?

mechanical response to a single Action potential

• twitch

• summation

• incomplete (unfused) tetanus

• complete (fused tetanus)

mechanical response to a multiple APs

maximum force from each contraction reaches a plateau

cannot see peaks and valleys

• twitch

• summation

• incomplete (unfused) tetanus

• complete (fused tetanus)

mechanical response to a multiple APs

not allowed to fully relax which results in increase of tension

• twitch

• summation

• incomplete (unfused) tetanus

• complete (fused tetanus)

mechanical response to a multiple APs

maximum possilbe force from each contraction reaches plateau

can still see peaks and valleys

• twitch

• summation

• incomplete (unfused) tetanus

• complete (fused tetanus)
