Study Notes
Types of Muscle Tissue
-
Smooth Muscle
- Non-striated, involuntary control.
- Controlled by the autonomic nervous system.
- Spindle-shaped fibers.
-
Skeletal Muscle
- Striated and voluntary; allows conscious control.
- Attached to bones, regulating body movements.
- Multinucleated fibers with nuclei located at the periphery.
- Limited mitotic ability; does not replicate.
-
Cardiac Muscle
- Striated and involuntary.
- Features branched fibers that communicate with adjacent cardiac cells.
- Contains intercalated discs for strong cell connections, equipped with desmosomes and gap junctions.
Connective Tissue Layers of Muscle
-
Epimysium
- Outermost layer, wraps the entire muscle belly.
-
Perimysium
- Middle layer; surrounds individual fascicles.
-
Endomysium
- Innermost layer; encases each muscle fiber or cell.
Muscle Example
- Biceps Muscle
- Composed of a muscle belly covered by epimysium.
- Fascicles represented as strands, akin to "hair-like" structures within the muscle.
