True or False: are muscles shorten by converting the chemical energy of ATP into mechanical energy

• true

• false

Skeletal muscle is...

• voluntary, branched, multinucleated

• striated, branched, involuntary

• voluntary, striated, multi-nucleated

• involuntary, non-striated, hollow

Cardiac muscle is...

• striated, branched, involuntary

• voluntary, branched, striated

• hollow organs, involuntary

• voluntary, striated, multi-nucleated

Smooth muscle is...

• voluntary, branched, striated

• involuntary, non-striated, branched

• voluntary, striated, multi-nucleated

• hollow organs, involuntary, non-striated

Which of the following is not a function of muscles?

• Movement

• Signalling

• Communication

• Body Heat Production

• Stablilty

Another name for muscle cell is...

• myofibril

• muscle cell

• muscle fiber

• fascicles

Which characteristic of muscles is correctly paired?

• Extensibility: shorten when stimulated

• Elasticity: returns to its original resting length after being stretched

• Conductivity: receive and respond to stimuli or other signals

• Responsiveness: local electrical change triggers a wave of excitation

• Contractility: capable of being stretched

True or False: Skeletal Muscle is composed of 2 types of tissues; muscular and connective

• False

• True

Correctly describe the epimysium.

• slightly thicker layer of connective tissue, surrounds a bundle of cells

• Thin layer of tissue surrounds each cell/fiber, allow room for nerve fibers

• Within the muscle

• Covers whole muscle belly, bend into connective tissue that separate muscle

Correctly describe the perimysium

• Covers whole muscle belly, bend into connective tissue that separate muscle

• slightly thicker layer of connective tissue, surrounds a bundle of cells

• outside the muscle

• Thin layer of tissue surrounds each cell/fiber, allow room for nerve fibers
