Question

What are the differences between cardiac (heart) and skeletal muscle contractile tissue?

Answer 1

Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac andsmooth muscle are involuntary whileskeletal muscle is voluntary. ... Whileskeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles, called intercalated discs.

Answer 2

Answer:

Cardiac muscle is involuntary and found only in the heart. Skeletal muscle is striated in regular, parallel bundles of sarcomeres. Cardiac muscle is striated, but the bundles are connected at branching, irregular angles called intercalated discs. Skeletal muscle tissue is about 15% denser than fat tissue.
