Study Notes
Overview of Muscle Tissue
- Muscle tissue facilitates movement in the body and helps in the transport of materials internally.
Types of Muscle Tissue
- There are three main types of muscle tissue:
- Smooth (visceral)
- Cardiac
- Skeletal
Smooth (Visceral) Muscle Tissue
- Composed of spindle-shaped cells.
- Each cell contains one centrally located nucleus.
- Primarily located in the walls of hollow organs, excluding the heart.
- Functions involuntarily, meaning it operates without conscious control.
Cardiac Muscle Tissue
- Features short, cylindrical cells that may branch (bifurcated).
- Contains one or two centrally located nuclei.
- Identified by intercalated discs that link cells for coordinated contractions.
- Displays striations, which are visible alternating light and dark bands.
- Also involuntary, facilitating the heart's rhythmic contractions without conscious control.
Skeletal Muscle Tissue
- Consists of long, cylindrical cells that are multinucleated.
- Nuclei are positioned at the periphery of the cells, not centrally located.
- Exhibits striations similar to cardiac muscle tissue.
- Under voluntary control, enabling intentional movement of the body.
