Question 6 (11.111111111 points)


Muscle tissue in the human body includes skeletal, cardiac, and smooth muscle. Each type has unique structures. What best explains why their structures are different?
Question 6 options:


Each muscle type has special structures that match its unique role in the body


Structural differences are random and not connected to their actual function


The muscle cells look different but actually contract in exactly the same way


All three muscle types are structurally different only because of their location

Answer 1

Each muscle type has special structures that match its unique role in the body.

Explanation: structure follows function — skeletal muscle is striated and multinucleated for strong, voluntary contractions; cardiac muscle has branched cells and intercalated discs for synchronized heartbeat; smooth muscle is nonstriated for slow, sustained contractions in organs.
