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.
