excitation-contraction coupling is:
One muscle cell only A skeletal muscle fiber comprises:
Slow-twitch fibers have Fast-twitch muscle fibers differ from slow-twitch
more myoglobin than fibers in which way(s)?
fast-twitch AND Slow-
twitch fibers are more
fatigue-resistant than
fast-twitch
Smooth muscle cells Smooth muscle differs from skeletal muscle in which
have only one nucleus way(s)?
AND Smooth muscle
contracts more slowly
than skeletal muscle
Z lines (from striated Smooth muscle dense bodies perform a similar
[cardiac & skeletal] function to:
muscles)

Ca++ enters the cell, Ca++ The correct sequence of events in smooth muscle
binds to calmodulin, contraction is:
myosin heads are
phosphorylated, myosin
binds to actin
Cardiac muscle cells Cardiac muscle differs from skeletal muscle in which
have only one nucleus way(s)?
and are branched
Both serve as the Intercalated disks:
insertion point for cardiac
muscle cells and contain
numerous gap junctions
and desmosomes
Is both limited by Excitation-contraction coupling in cardiac muscle:
parasympathetic activity
and is similar to that seen
in skeletal muscle
Are characterized by a Action potentials in cardiac muscle cells:
broad plateau as Ca++
enters the cell
Depolarizing signals pass through the atrial
Gap junctions
musculature via:
Closure of the mitral The first "heart sound" is made by:
valve AND Closure of the
tricuspid valve
Atrial diastole The greatest blood pressure is achieved at:
Anchor the leaflets of the Papillary muscles:
A-V valves AND Are
inserted into the
ventricular musculature
Varies with heart rate Cardiac output:
(and stroke volume)
