List in sequence the events involved in excitation-contraction
coupling in skeletal muscle contraction and relaxation, and underscore
all the membranes involved.
Why does force continue to rise during a twitch for some time
after the myoplasmic Ca++ has fallen well below its
peak concentration?
List the characteristics structures that you might look for
in histological sections which would enable to descriminate between
skeletal, cardiac and smooth muscle. You need to specify the
plane (transverse or longitudinal) and the objective lens magnification.
What are the distinguishing characteristics of slow type I
motor units?
How is the force generated by a skeletal muscle varied?
What evidence supports a sliding filament-cross-bridge mechanism
of contraction in smooth muscle?
What are the general factors that explain the extraordinary
functional diversity among smooth muscles from various organs?
List the steps that link an increase in myoplasmic Ca++
to contraction in smooth muscle.
What factors determine relaxation in smooth muscle?
What determines the rate of contraction in smooth muscles?
