What are the 5 major properties of the muscular system?
Terms in this set (5)
- Excitability- can be stimulated by chemical signals, nerves and stretch.
- Conductivity- the signal for a muscle to contract is spread from the point of stimulation throughout the entire muscle.

What are four characteristics of muscles?
All muscle tissues have 4 characteristics in common:
- excitability.

What are the properties and functions of muscles?
All muscle cells share several properties: contractility, excitability, extensibility, and elasticity:
- Contractility is the ability of muscle cells to forcefully shorten.
- Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone.
What are three type of muscles?
