Published	09/07/2023	Smooth muscle is part of the {{c1::autonomic}} nervous system
Published	09/07/2023	Smooth muscle cells are {{c1::small}} in size and contain {{c1::one}} nucleus
Published	09/07/2023	The {{c1::sliding filament mechanism}}, in which myosin filaments bind to and move actin filaments, is the basis for shortening of stimulated mus…
Published	09/07/2023	Changes in the membrane potential lead to contraction; called {{c1::E-C Coupling (excitation-contraction coupling)}}
Published	09/07/2023	Myosin and actin interactions are regulated by {{c1::calcium}} ions.
Published	09/07/2023	Striated skeletal muscle fiber is part of the {{c1::somatic}} nervous system
Published	09/07/2023	Striated skeletal muscle fibers are {{c1::large}} in size and have {{c1::multiple}} nuclei
Published	09/07/2023	Striated cardiac muscle fibers are {{c1::small}} in size and contain {{c1::1-2}} nuclei
Published	09/07/2023	Striated cardiac muscle fiber is part of the {{c1::autonomic}} nervous system
Published	09/07/2023	In smooth muscle, thin filaments are {{c1::diagonally}}anchored to the plasma membrane by {{c2::dense bodies (analogous to z lines)}}
Published	09/07/2023	{{c1::Alpha-actinin}} is a major component of {{c2::dense bodies}} in smooth muscle and {{c2::Z-lines}} in skeletal muscle
Published	09/07/2023	Smooth muscle is anchored to {{c1::intermediate filaments}} via {{c2::dense bodies}}
Published	09/07/2023	Cross bridge cycling is controlled by {{c1::calcium}}
Published	09/07/2023	During cross-bridge cycling, calcium regulates {{c1::myosin}} in smooth muscle and {{c1::actin}} in skeletal muscle
Published	09/07/2023	Once activated, smooth muscle thick filaments continue to generate tension until they are {{c1::dephosphorylated}}
Published	09/07/2023	Smooth muscle contraction is modulated by {{c1::stretch}} in arterioles
Published	09/07/2023	Smooth muscle contraction is modulated by {{c1::hormones (oxytocin)}} in the uterus
Published	09/07/2023	Rhythmic patterns of action potentials and contraction in smooth muscle cells is called {{c1::Pacemaker Activity}}
Published	09/07/2023	{{c2::Single-Unit}} Smooth Muscle has {{c1::gap junctions}} which spread membrane potentials between neighboring cells
Published	09/07/2023	In {{c1::Multi-Unit}} Smooth Muscle, each muscle cell is innervated and there are few or no gap junctions
Published	09/07/2023	{{c1::Multi-Unit}} smooth muscle is used primarily for graded responses and fine control (e.g. large arteries and airways)
Published	09/07/2023	{{c1::Single-Unit}} Smooth Muscle is used primarily for synchronous changes in activity, including stretch-activation and pacemaker function (found in…
