Study Notes
Characteristics of Muscular Tissue
- Voluntary (skeletal) and involuntary (smooth and cardiac) types
- Specialized for contraction and relaxation
- High degree of elasticity and extensibility
Types of Muscular Tissue
Skeletal Muscle (Voluntary)
- Attached to bones and helps move body parts
- Striated (striped) appearance under microscope
- Multinucleated (many nuclei)
- Voluntary control (conscious movement)
Smooth Muscle (Involuntary)
- Found in hollow organs (e.g., digestive tract, blood vessels)
- Non-striated (smooth) appearance under microscope
- Spindle-shaped cells with single nucleus
- Involuntary control (automatic movement)
Cardiac Muscle (Involuntary)
- Found in heart
- Striated appearance under microscope
- Branching fibers with single nucleus
- Involuntary control (automatic heartbeat)
Functions of Muscular Tissue
- Movement and locomotion (skeletal muscle)
- Regulation of body functions (smooth muscle)
- Pumping blood (cardiac muscle)
- Maintenance of posture and balance (skeletal muscle)
Characteristics of Muscular Tissue
- Muscular tissue is specialized for contraction and relaxation
- Has a high degree of elasticity and extensibility
- Comprises two main types: voluntary and involuntary
Types of Muscular Tissue
Skeletal Muscle (Voluntary)
- Attached to bones, enabling movement of body parts
- Displays a striated (striped) appearance under a microscope
- Consists of multinucleated cells
- Controlled voluntarily, allowing for conscious movement
Smooth Muscle (Involuntary)
- Found in hollow organs, such as the digestive tract and blood vessels
- Exhibits a non-striated (smooth) appearance under a microscope
- Composed of spindle-shaped cells with a single nucleus
- Controlled involuntarily, resulting in automatic movement
Cardiac Muscle (Involuntary)
- Exclusive to the heart, responsible for pumping blood
- Displays a striated appearance under a microscope
- Consists of branching fibers with a single nucleus
- Controlled involuntarily, regulating the heartbeat automatically
Functions of Muscular Tissue
- Enables movement and locomotion through skeletal muscle
- Regulates various body functions, such as digestion and blood pressure, via smooth muscle
- Pumps blood throughout the body through cardiac muscle
- Maintains posture and balance, thanks to skeletal muscle
