What is the term used to describe a muscle action of drawing a body part downward?
What is a depressor
100
A movement that decreases the angle of the joint is called
What is Flexion
100
Each muscle has three layers of connective tissue. These layers are called what
What are the Epimysium, the Perimysium, and the Endomysium.
100
Define a Twitch
What is a single stimulus-contraction-relax-action sequence in a muscle fiber
100
What are the 3 types of muscle tissue?
What are Skeletal muscle, Cardiac muscle, and Smooth muscle
200
This term characterizes a "short" muscle
What is Brevis
200
Communication between the nervous system and a skeletal muscle fiber occurs at a specialized intercellular connectinon known as the what
What is the Neuromuscular Junction
200
These stem cells take part in repair of damaged muscle tissue
What are Myosatellite Cells
200
What are the 3 different phases of a twitch?
What are the Latent Phase, the Contraction Phase, & the Relaxation Phase
200
What layer(s) of the connective tissue in muscles contain blood vessels and nerves that supply the muscle fibers?
What are the Perimysium and the Endomysium.
300
This is a dense layer of collagen fibers that surrounds the entire muscle. It separates the muscle from nearby tissues and organs. It is connected to the deep fascia, a dense connective tissue layer.
What is the Epimysium.
300
In this type of contraction the muscle does not shorten, instead it lengthens
What is Eccentric Contraction
300
During development, these groups of embryonic cells fuse, forming individual multinucleate skeletal muscle fibers.
What are Myoblasts
300
If a skeletal muscle is stimulated a second time immediately after the relaxation phase has ended, the resulting contraction will develop a slightly higher maximum tension than did the first contraction. The increase in peak tension will continue over the first 30-50 stimulations. After that, the amount of tension produced will remain constant. What is this pattern called?
What is Treppe
300
Concentric and Eccentric contractions are 2 forms of what type of contraction?
What is an Isotonic Contraction.
400
This term is known as the plasma membrane of a muscle fiber.
What is the Sarcolemma
400
Differentiate between Adduction and Abduction
What is toward the midline; away from the midline
400
These filaments are comprised primarily of actin.
What are Thin Filaments
400
If a second stimulus arrives before the relaxation phase has ended, a second, more powerful contraction occurs. The addition of one twitch to another in this way is called what?
What is Wave Summation
400
This period begins immediately after a period of muscle activity and continues until conditions inside the muscle have returned to pre-exertion levels.
What is the Recovery Period
500
When a skeletal muscle contracts, the H bands & I bands of the sarcomeres get smaller, the zones of overlap get larger, the Z lines move closer together, and the width of the A band remains constant. What is this explanation known as?
What is The Sliding Filament Theory.
500
In which plane does Abduction of the arm happen in?
What is Frontal or Coronal Plane
500
This combination of a pair of terminal cisternae plus a T tubule is known as a what
What is a Triad
500
When a higher stimulation frequency eliminates the relaxation phase, this occurs
What is Complete Tetanus.
500
At peak levels of activity, the muscle cell relies heavily on this to generate ATP, because the mitochondria cannot obtain enough oxygen to meet the existing ATP demands.
What is Anaerobic Metabolism (Glycolysis)
