excitability
|
|
|
contractibility
|
|
|
extensibility
|
|
|
elasticity

Explanation:
Detailed explanation-1: -Following contraction or extension, a muscle can return to its original length when relaxed due to a quality of muscle tissue called elasticity. It can recoil back to its original length due to elastic proteins.
Detailed explanation-2: -The last phase is the relaxation phase, when tension decreases as Ca++ ions are pumped out of the sarcoplasm back into the sarcoplasmic reticulum, returning the muscle fibers to their resting state. Figure 10.4.
Detailed explanation-3: -Answer and Explanation: The ability of a muscle cell to be stretched is called c) elasticity. Muscle elasticity is important for maintaining full range of motion.
