Vedclass · Answer

(A) Cardiac muscle fibers are structurally similar to skeletal muscle fibers because they both exhibit striations due to the arrangement of actin and myosin filaments. However,they differ functionally because cardiac muscles are involuntary (controlled by the autonomic nervous system),whereas skeletal muscles are voluntary (controlled by the somatic nervous system). Therefore,cardiac muscle fibers are striated and involuntary.
