Here are some of the features of each type of muscle.
Explanation:
Skeletal Muscle
(From theydiffer.com)
1. Function
- Aid in movement of the body
2. Structure
- Distributed throughout body
- Attached to the skeleton by tendons.
- Striated
- Well-supplied with nerves and blood vessels.
- Multinucleated cells
3. Other features
- Voluntary
- Activated by central nervous system
- Stretch and resume original shape.
- Contract rapidly but tire quickly.
Smooth Muscle
(From http://legacy.owensboro.kctcs.edu)
1. Function
- Maintain flow of fluid and food along through internal organs.
2. Structure
- In lining of internal organs
- Smooth appearance under a microscope.
- Non-striated
3. Other Features
- Involuntary
- Regulated by autonomic nervous system.
- Slow, rhythmic contraction
- Fatigue slowly.
Cardiac Muscle
1. Function
- Pump blood away from the heart towards the lungs and throughout the body
2. Structure
- Along walls of heart
- Striated
- Good blood supply.
- Mononucleated cells
3. Other Features
- Involuntary
- Controlled by autonomic nervous system
- Tireless
