Which muscle tissue has intercalated discs that help synchronize heart contractions?
hard Q10 of 15
Step-by-Step Solution
Step 1: Understand muscle tissue structure
The question asks which muscle has intercalated discs for synchronized contractions.Step 2: Recall muscle features
Cardiac muscle has intercalated discs; skeletal muscle does not; smooth muscle lacks striations and discs; voluntary muscle is skeletal muscle.Step 3: Explain why others are incorrect
Skeletal muscle is voluntary and lacks intercalated discs; smooth muscle is involuntary and non-striated; voluntary muscle is not a tissue type but a control type.Final Answer:
Cardiac muscle → Option DQuick Check:
Cardiac muscle = has intercalated discs for heart contractions ✅
Quick Trick: Intercalated discs are unique to cardiac muscle tissue.
Common Mistakes:
MISTAKES- Confusing skeletal muscle with cardiac muscle due to striations.
