Quiz 3 Part 4 Flashcards
As we increase stimulation, we recruit what?
More muscle fibers
The smaller the muscle the quicker the what?
The relaxation is going to be
What is Muscle Twitch?
One stimulation, contraction and relaxation
What is a Latent Period?
Gap between stimulation from nerve & actual muscle contraction
What is the Treppe Effect?
When a muscle contracts, it may be only half as strong as in later contractions in response to a stimulation
What is Muscle Tone?
A state of semi-contraction
What are the two types of muscle contraction?
Isotonic & Isometric
What is Isometric Contraction?

What is Muscular Dystrophy?
When all of our muscle starts to get eaten away and is replaced by fat and connective tissue ( Affects kids/ No cure)
What is Wave Summation?
The gradual increase of the frequency of stimulation at a constant intensity allowing for only slight periods of relaxation
What is Incomplete Tetanus? (Unfused)
Rapid increase of the frequency of stimulation
What is Complete Tetanus? (Fused)
Smooth, continuous contraction with no relaxation
