Muscles Flashcards
What is muscle tissue?
Tissue made of highly specialised, elongated cells with elastic properties.
What do cells in muscle tissue do when stimulated?
They contract.
What is the purpose of muscle tissue?
To provide the source of power for movement and posture in the body.
What are the 4 functions of muscle tissue?
- Movement
- Posture
- Stabilization
- Thermogenesis
Define thermogenesis
The generation of heat.
How does the muscle tissue produce heat?
Through normal contractions and shivering.
(Physics)
Define Excitability.
(aka irritability)
Functional characteristics of muscle cells
The ability to receive and respond to a
stimulus.
Define Contractility
Functional characteristics of muscle cells
The ability of muscle tissue to shorten.
Define Elasticity.
Functional characteristics of muscle cells
The ability of muscle tissue to regress.
Regress - return to original state.
Define Extensibility.
The ability to be stretched without damage.
Define Conductivity.
The ability to conduct excitation over the length of the muscle.
What are the functional characteristics of muscle tissue?
- Excitability
- Contractility
- Elasticity
- Extensibility
- Conductivity
- skeletal muscle
What is the muscular system composed of?
All the voluntary skeletal muscles in the body.
