Smooth muscle lines hollow organs (e.g., intestines, blood vessels, bronchi), features spindle-shaped, uninucleate cells, lacks striations, and is regulated involuntarily via the autonomic nervous system and local factors (hormones, stretch). It contracts slowly, can sustain tone, and exhibits myogenic activity in some tissues. Skeletal muscle attaches to the skeleton via tendons, shows striations from sarcomere organization, consists of long multinucleated fibers, and is under voluntary somatic control (though reflexes also activate it). Option A inverts properties; C describes skeletal, not smooth. D is the opposite of smooth muscle’s physiology; skeletal muscle is the one associated with voluntary control and variable fatigue. TEAS frequently compares muscle types: cardiac muscle is striated, uninucleate, branched, with intercalated discs and involuntary control. Remember the triad: skeletal (striated, voluntary, multinucleated), smooth (non-striated, involuntary, single nucleus), cardiac (striated, involuntary, single nucleus, intercalated discs).
