Conductivity of cardiac muscle cells: all channels involved in releasing ions into and out of the cell

What allows cardiac muscle and smooth muscle to be excited and contract nearly simultaneously? ganglia intermediate fibers cross bridges motor and plates Gap junctions

The amount of resistance overcome in proportion to the amount of effort expended is known as:  an eccentric contraction.  an isometric contraction.  the mechanical advantage of a muscle.  the physiological advantage of a muscle.

Skeletal, cardiac, and smooth muscle cells are distinctly different from each other in numerous ways. Indicate how they differ in these specific ways (give the anatomical differences and the corresponding physiological consequences – structure and function). -Type of innervation -Contractile filament organization -Mechanism for contracticle activation and final contractile response
