Question

how is muscles not chatracterized by​

Answer 1

Answer:

All muscle tissues have 4 characteristics in common:

• excitability.
• contractility.
• extensibility - they can be stretched.
• elasticity - they return to normal length after stretching.

Answer 2

Answer:

Cardiac muscle is characterized by striped muscle fibers, connected together by intercalated disks, where the membranes are specialized to allow electrical signals to pass easily. Like smooth muscles, cardiac muscles can remain in contraction for a sustained period. Like skeletal muscles, cardiac muscles also contract quickly. The formation of contractile proteins in cardiac muscle cells also allows for stronger contractions when the fibers are stretched, which makes the heart pump more efficiently.
