What are the three types of muscle tissues?
Cardiac, Smooth, Skeletal
What are the three types of muscle levers?
1st class, 2nd class, 3rd class
The middle of the muscle is called the
Belly
How many units of ATP are used when a myosin and actin filament engage during contraction?
1 unit ATP
A bundle of muscle fibers is called a ____
Fascicle
What kind of muscle tissue is found within your digestive system?
Smooth muscle tissue
The location of ___, ____, and ____ differentiate the 3 types of levers
Force, fulcrum, and load
Muscles are attached to bones by
Tendons
The buildup of ____ makes your muscles sore
Lactic acid
Each muscle fiber is made up of _____
Myofibrils
What type of muscle tissue is striated and used to control your voluntary muscles?
Skeletal
This type of lever has the load between the fulcrum and force
2nd class lever
What is a synergist?
Muscles that help contraction in that same direction
Explain oxygen debt
A difference occurs between the amount of oxygen available and the amount required and you are “out of breath”
What membrane surrounds the entire muscle?
Epimysium
What type of muscle tissue aids in heart beats?
Cardiac muscle tissue
This type of lever has the fulcrum between the load and force
1st class lever
Explain the difference between the antagonist and the prime mover
Antagonist: opposing muscle relaxing during motion
Prime mover: muscle doing the action (contracting)
Explain intense exercise
Muscles are worked strenuously and the glucose supply is exhausted.
Which two structures engage to cause muscle contraction
What type of muscle tissue is striated and is used to control your skeletal bones?
Skeletal muscle tissue
This type of lever has the force between the fulcrum and the load
Explain the difference between the origin and the insertion
Origin: The attachment of the tendon to the more stationary bone
Insertion:The attachment to the more movable bone
Explain muscle fatigue
ATP is no longer efficiently being used for cross-bridges
What are the two types of protein filaments that myofibrils contain
Actin and Myosin
