4. In the study of histology, understanding muscle tissue types is essential. Which of the following statements accurately reflects a key difference between the three types of muscle tissue?
a) Skeletal muscle is involuntary and striated, cardiac muscle is voluntary and non-striated, while smooth muscle is striated and involuntary.
b) Skeletal muscle fibers are multinucleated and under voluntary control, cardiac muscle is striated and involuntary with intercalated discs, and smooth muscle is non-striated and involuntary, allowing for various functions across different organs.
c) All muscle tissue types are involuntary and share the same structural characteristics, differing only in their locations in the body.
d) Cardiac muscle fibers are capable of rapid regeneration, while skeletal and smooth muscle fibers have limited regenerative abilities.
