what are the functional characteristics of muscles?
excitability and conductivity, contractibility, extensibility, and elasticity
The functional characteristics of muscles are:
1. Contractility: The ability of muscles to contract or shorten in response to a stimulus is called contractility. This is the fundamental function of muscles, to generate force and produce movement.
2. Excitability: Muscles possess the ability to respond to various stimuli, such as electrical signals from nerves or chemicals. This property is called excitability or irritability.
3. Extensibility: Muscles can be stretched or extended, allowing for a range of motion and flexibility. This property is referred to as extensibility.
4. Elasticity: The ability of muscles to return to their original shape or size after being stretched is called elasticity. This property allows for efficient energy transfer during movements.
Together, these functional characteristics allow muscles to perform a variety of actions, from basic movements like breathing and standing to complex athletic movements like sprinting or jumping.
