Which Characteristics Describe Both Skeletal and Cardiac Muscle

Question

Which characteristics describe both skeletal and cardiac muscle?
A)striations
B)autorhymicity
C)cell shape
D)autonomic control
E)somatic control

Accepted Answer

Both skeletal and cardiac muscle have striations due to the organization of actin and myosin filaments within the muscle cells. Choice B) is incorrect as autorhythmicity is a characteristic specific to cardiac muscle only, and choice C) is incorrect as the cell shape of skeletal and cardiac muscle differ. Choice D) is partially correct as cardiac muscle is under autonomic control, but skeletal muscle is under somatic control (choice E), which is not shared by cardiac muscle.
