What is contractility excitability extensibility and elasticity?
All muscle cells share several properties: contractility, excitability, extensibility, and elasticity: Contractility is the ability of muscle cells to forcefully shorten. Extensibility is the ability of a muscle to be stretched.
What are the 4 properties of muscles?
All muscle tissues have 4 characteristics in common:
- excitability.
- contractility.
- extensibility – they can be stretched.
- elasticity – they return to normal length after stretching.
What are the 5 major properties of the muscular system?
There are 5 major properties to the muscular system.
- Excitable or Irritable.
- Contractible.
- Extensible.
- Elasticity.
- Adaptability.
What are the 3 components of muscular contraction?
The sequence of events that occurs when a muscle contracts depends on three other factors: calcium and two inhibitory proteins, troponin and tropomyosin. Voluntary muscle contraction begins with electrical impulses at the myoneural junction, initiating the release of calcium ions.
What is muscle extensibility?
Muscle extensibility: ability of a muscle to extend to a predetermined endpoint.
What is the difference between contractility and extensibility?
Contractility allows muscle tissue to pull on its attachment points and shorten with force. ( muscles can only pull, never push.) Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended.
What is excitability in muscular system?
Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended. Elasticity is the ability to a muscle to return to its original length when relaxed.
Which one of the following is a property of muscles a excitability B Elasticity C extensibility D all of these?
Extensibility is the correct ans.
What is the difference between excitability and contractility?
Contractility is the ability of muscle cells to forcefully shorten. ( muscles can only pull, never push.) Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended.
What is Auxotonic contraction?
An auxotonic contraction occurs when neither the force nor the length remain constant; essentially a combination of the variable isometric and isotonic states of contraction.
