Multiple Choice
Which type of muscle tissue contains intercalated discs that help coordinate contraction between cells?
A
Dense regular connective tissue
B
Cardiac muscle
C
Skeletal muscle
D
Smooth muscle
Verified step by step guidance1
Step 1: Understand the types of muscle tissue: skeletal, smooth, and cardiac muscle, each with distinct structural and functional characteristics.
Step 2: Recall that intercalated discs are specialized connections between cells that facilitate synchronized contraction, a feature unique to cardiac muscle tissue.
Step 3: Recognize that dense regular connective tissue is not muscle tissue but connective tissue, so it does not contain intercalated discs.
Step 4: Note that skeletal muscle fibers are multinucleated and striated but lack intercalated discs; they contract voluntarily and independently.
Step 5: Understand that smooth muscle is non-striated, involuntary, and does not have intercalated discs; it contracts more slowly and independently.
