Study Notes
Characteristics of Muscle Types
- Multinucleated and peripherally located muscle tissue is skeletal muscle.
- Smooth muscles are found in the walls of hollow organs, such as the digestive tract, blood vessels, and airways.
- Centrally located muscle tissue with a single nucleus is smooth muscle.
- Cardiac muscle tissue is found in the heart.
Function of Smooth Muscles
- Smooth muscles are involved in involuntary movements, such as contractions of the digestive tract and airways.
- They are found in the walls of hollow organs and help to move substances through these organs.
Cardiac Muscles
- Cardiac muscle tissue is found in the heart and is involved in pumping blood throughout the body.
- Cardiac muscles are striated, but they are involuntary, meaning that they are not under conscious control.
Voluntary and Involuntary Muscles
- Voluntary muscles are under conscious control and are typically skeletal muscles attached to bones.
- Examples of voluntary muscles include the biceps and quadriceps.
- Involuntary muscles are not under conscious control and are typically smooth muscles or cardiac muscles.
- Examples of involuntary muscles include the muscles in the digestive tract and the heart.
Structural Differences
- Skeletal muscles have a striated appearance with multiple nuclei per cell.
- Smooth muscles have a non-striated appearance with a single nucleus per cell.
- Cardiac muscles have a striated appearance, but they are involuntary and have a single nucleus per cell.
