Smooth Muscle Physiology — Flashcards
_____ smooth muscle systems are innervated by a single nerve ending (en passant endings of nerve fibers)
_____-unit smooth muscle systems respond to hormones and other circulating systems
Resting membrane potential of a _____ muscle is -20 to -65 mV
What type of muscle fibres do not have striations, troponin or T tubules?_____
A sustained contraction with little expenditure of energy is made possible by a _____ mechanism in smooth muscle
Sympathetic stimulation (norepinephrine) of a smooth muscle produces _____ potentials and relaxation.
Chemical Events during Muscle Contraction: The **power stroke** is initiated by the release of _____ from the myosin head.
_____ is absent in smooth muscle but present in skeletal muscle
Hint: Micro-component
Fast twitch muscle fibers are _____ due to decreased myoglobin concentration
Hint: (color)
After the power stroke in muscle contraction, binding of a new _____ molecule causes detachment of the myosin head from the actin filament
