Question

which of the following is a feature shared by cardiac muscle and skeletal muscle?

muscle fiber striations

dependence upon nervous stimulation

communication via electrical (gap) junctions

intercalated discs

autorhythmicity

Explanation:

Cardiac muscle and skeletal muscle both have muscle fiber striations. Cardiac muscle has intercalated discs and autorhythmicity and communicates via electrical (gap) junctions, which skeletal muscle lacks. Skeletal muscle requires nervous stimulation to contract while cardiac muscle can contract spontaneously.

Answer:

Muscle fiber striations
