antagonistic pairs
two muscles which work in opposing directions to one another
striated muscle found in the heart
the process used to convert glucose and oxygen into a useable form of energy called ATP
when the muscle becomes shorter and thicker

Named for it's size
gluteus minimus, gluteus medius
Named for their shapes
Deltoid, Rhomboid, Trapezius
Named for their locations
Vastus lateralis, vastus medialis, vastus intermedius
Named for the number of heads (origins)
Biceps brachii, triceps brachii,
Named for their functions
Adductors, flexors
Match the following
Origin
the point of a muscle which attaches to a stationary bone
Insertion
the point of a muscle which attaches to a bone that performs the movement
Belly
the largest part of the muscle containing the muscle cells
Think about the action of the triceps. Then label the origin, belly, and insertion.
Synergist
muscles working together in the same direction of motion
Prime Mover or agonist
a muscle that is most important in the creation of a specific action or movement
Antagonist
a muscle that opposes the action of another
Which type of contraction produce movements by muscles shortening?
Isotonic contractions
Isometric contractions
Twitches
Resistance exercises
Which of the following is the opposite movement to extension?
Flexion
Rotation
Circumduction
Adduction
How is muscle fatigue best described?
The inability to generate sufficient quantities of ATP due to feedback regulation of synthesis
A total lack of ATP
Insufficient intracellular quantities of ATP due to excessive consumption
Inadequate numbers of mitochondria
Which of the following stabilizes the origin of a prime mover?
Synergisty
Antagonist
Fixator
Prime mover
What function does creatine phosphate serve in the muscle cells?
CP breaks down glucose into carbon dioxide and water to release energy
CP breaks down glucose without oxygen
CP transfers a phosphate group to ADP to resynthesize ATP
CP blocks oxygen to create oxygen deficit
Which type of muscle contraction occurs without a change in length?
Isotonic contractions
Tetanus contractions
Isometric contractions
Twitches

Which of the following provide ATP for muscles
creatine phosphate
aerobic respiration
anaerobic respiration/glycolysis
synaptic transmission
Which are characteristic of fatigue?
I. A result of transient overtraining
II. A reversible, exercise-induced decline in performance
III. A permanent decline in physical and mental health
I only
I and II
II and III
I, II and III
Creatine Phosphate:
is produced by the process of anaerobic respiration.
can replace ATP in binding myosin molecules during contraction.
acts as an energy reserve in muscle tissue.
is only formed during strenuous exercise.
All of these are correct.
