pes Flashcards
what are the characteristics of skeletal muscle tissue
is a highly organized tissue composed of bundles of muscle fibres called myofibers which contain several myofibrils.
what is contractibility
shortening the muscle and decreasing the angle between 2 points.
what is extendibility
lengthening the muscle and increasing the angle between 2 points.
what is elasticity
how much a muscle can stretch
how do the origin and insertion points determine the action of the muscle
Origin is relatively the less movable end of the muscle/tendon that is attached to a bone.
Insertion is the more flexible end of the muscle that is usually attached to a bone via tendons.
what are the origin and insertion points of skeletal muscles
The origin is the attachment site that doesn’t move during contraction, while the insertion is the attachment site that does move when the muscle contracts.
what is origin
the point at which the muscle joins the stationary bone.
what is insertion
the point where the muscle’s tendon joins the moving bone.
how long does ATP-CP last for
10 seconds of high intensity physical activity.
how long does Lactic Acid last for
30sec to 2 minutes

10-15 seconds.
how long does aerobic last for
2-3 minutes or as long as you need
