Question

All the following are properties of skeletal muscles except

• A. Excitability
• B. Extensibility
• C. Contractility
• D. Rhythmicity

Answer 1

The correct option is D Rhythmicity

Rhythmicity is a property of cardiac muscles in cardiology, the ability to beat, or the state of beating, rhythmically without external stimuli.
Excitability: this refers to muscle tissue being able to react to nervous stimulation.
Extensibility: this refers to the ability of muscle tissue to lengthen when contracting and provide the effort required to move the lever system (the bones and joints), producing coordinated movement.
Contractility -: this refers to the capacity of a muscle to contract or shorten forcibly when stimulated by nerves and hormones (excitability).
