Lecture 2

Question 1

What do the elastic elements in skeletal muscle connect, which aids in contraction?

Answer 1

they connect the contractile elements to the tendons. (account for passive force of a contraction)

Question 2

epimysium, perimysium, endomesium, and titin are all what kinds of elements?

Answer 2

elastic elements

Question 3

What is the difference between isotonic contractions and isometric contractions?

Answer 3

they are the same until you generate enough force to pick an object up. That is when the muscle shortens in an isotonic contraction.

Question 4

What does a length/tension curve display?

Answer 4

displays the relationship between force and tension during contraction.

Question 5

How do you calculate the total force of a contraction (Ft)?

Answer 5

Contraction force + Passive force (Fc+Fp)

Question 6

what does lo account for on a length/tension curve?

Answer 6

the length of a muscle at maximum force/tension.
