|
1. Support
2. Protection 3. Movement 4. Maintain body temperature 5. Guard orifices - gives contrl over swallowing, defecation, and urination 6. Allows for breathing (diaphram is a skeletal muscle) |
|
Name the muscle sheaths of the skeletal muscle starting at the largest most outer layer and working to a single muscle fiber.
|
Epimysium to the perimyseum, which wraps the fiscicle, then the endomysium, which wraps the miscle fiber.
|
|
How many muscles does the body have?
|
Close to 700 muscles
|
|
What does it mean when someone says a skeletal muscle is excitable?
|
That the muscle can generate an electrical current call and Action Potential.
|
|
What does it mean when someone say a skeletal muscle can show contractability?
|
This means the muscle can generate a force.
|
|
What is the endomysium?
|
It is the ariolar CT wrapped around each muscle cell
|
|
What is the fascicle?
|
It is a groups of muscle cells in the muscle organ that are wrapped by the permysium
|
|
What is the epimysium?
|
It is dense irregular CT that surrounds the muscle organ.
|
|
Name the four characters of the skeletal muscle.
|
1. They are excitable (can generate electrical current)
2. Show contractility (can generate force, shortening) 3. Have elasticity (can be twisted and hold shape) 4. Have extensibility (Can be stretched) |
|
What is a muscle organ?
|
Muscle organs are all of the different muscles we are learning. The covering is called epimysium
