Question

Difference between striated, smooth and cardiac muscle
​

Answer 1

Answer:

Cardiac and skeletal muscles are "striated" in that they contain sarcomeres and are packed into highly regular arrangements of bundles; smooth muscle has neither. While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles (called intercalated discs).

Answer 2

Differentiate between striated, unstriated and cardiac muscles on the basis of their structure and site/location in the body.

Difference between striated, unstriated and cardiac muscles

Striated muscles Unstriated muscles Cardiac muscles

Structure Also known as skeletal muscles, they have striated, tubular, multinucleated, unbranched and tubular fibres. Also known as smooth muscles, they have non-striated, spindle shaped, uninucleated fibres. Cardiac muscles have striated, tubular, uninucleated, branched fibres.

Location They are found attached to skeleton. They are found in walls of internal organs. They are found in walls of heart.
