What characteristics define cardiac muscle when compared to
other types of muscle (like smooth and skeletal)? in terms of size,
arrangement, appearance.
Indicate whether (a) skeletal (b) cardiac (c) smooth muscle has
the following characteristics. A characteristic may apply to more
than one muscle type.
_______ contraction usually voluntary
_______ contraction usually involuntary
_______ regulated mostly by somatic nerves
_______ regulated mostly by autonomic nerves
_______ striated
_______ non-striated
_______ able to stretch
_______ elastic
Describe at least FOUR processes in neurons and/or myocytes
(muscle cells: skeletal, smooth, & cardiac) in which Calcium
Ions (Ca++) function as important intracellular secondary
messengers. Diagram how calcium exerts its effect on cells in each
of these cases (what molecules does it act upon, and what is the
result?).

muscle and skeletal muscle?
Select one: _
a. Striated arrangement of the actin and myosin filaments
_
b. Presence of T tubule network
c. Ability to contract in the absence of an action
potential
d. Dependence of contraction on Ca+2 ions
2/ Which of the following conditions causes bleeding tendency
after prolonged exposure to hazardous irradiation?
Select one: _
a. Vitamin K deficiency _
b. Hemophilia L
c. Chronic liver...
compare the contraction mechanism of skeletal, cardiac, and smooth
muscle fibers.
distinguish among the CNS, PNS, and the ANS.

functions of each component.
You should be able to:
