AND 100% CORRECT ANSWERS GRADED
A+
What are the 4 properties of muscle tissue? - CORRECT ANSWER: excitability,
contractility, extensibility, elasticity
What are the types of muscular tissue? - CORRECT ANSWER: skeletal, cardiac,
smooth
What is the function of skeletal muscle? - CORRECT ANSWER: movement of
bones, posture
What is the function of cardiac muscle? - CORRECT ANSWER: pump blood
throughout the body
What is the function of smooth muscle? - CORRECT ANSWER: contraction
What are connective tissue components? - CORRECT ANSWER: epimysium,
perimysium, endomysium
Fibers found in connective tissue - CORRECT ANSWER: collagen, elastic, reticular
function of connective tissue - CORRECT ANSWER: bind, support, protect, fill
spaces, store fat, produce blood cells
skeletal muscle - CORRECT ANSWER: striated and voluntary
, 2|P a g e
cardiac muscle - CORRECT ANSWER: Involuntary muscle tissue found only in the
heart, and striated
smooth muscle - CORRECT ANSWER: Involuntary muscle found inside many
internal organs of the body, and no striations
sliding filament theory - CORRECT ANSWER: theory that actin filaments slide
toward each other during muscle contraction, while the myosin filaments are still
twitch contraction - CORRECT ANSWER: the brief contraction of all the
muscle fibers in a motor unit in response to a single action potential in its motor
neuron
frequency of stimulation - CORRECT ANSWER: the higher the frequency, the
greater the force
isotonic contraction - CORRECT ANSWER: muscle shortens because muscle
tension exceeds load
isometric contraction - CORRECT ANSWER: Muscle contracts but there is no
movement, muscle stays the same length
origin - CORRECT ANSWER: attachment to stationary bone
Insertion - CORRECT ANSWER: attachment to movable bone
lever system - CORRECT ANSWER: Consists of a lever (bone), effort (muscle
action), resistance (weight of object to be moved), and fulcrum (joint).
