Muscular Tissue
Responsible for movement, composed of contractile cells, categorized as skeletal, smooth, and cardiac muscle.
What is Muscular Tissue?
An individual cell of muscle tissue, typically elongated and capable of contraction.
Key points
- Identify and differentiate the three types of muscular tissue.
- Describe the structural and functional characteristics of skeletal, smooth, and cardiac muscles.
- Explain the mechanism of muscle contraction at a basic level.
- Relate the function of muscular tissue to overall body movement and physiological processes.
Common exam trap
Confusing voluntary and involuntary muscle types.
Definitions
- Term
Muscle Fiber
- Meaning
An individual cell of muscle tissue, typically elongated and capable of contraction.
- Term
Striated Muscle
- Meaning
Muscle tissue characterized by the presence of visible bands or striations, typically skeletal and cardiac muscle.
- Term
Non-striated Muscle
- Meaning
Muscle tissue lacking visible bands or striations, typically smooth muscle.
- Term
Voluntary Muscle
- Meaning
Muscle that can be consciously controlled, such as skeletal muscle.
- Term
Involuntary Muscle
- Meaning
Muscle that cannot be consciously controlled, such as smooth and cardiac muscle.
- Term
Intercalated Discs
- Meaning
Specialized junctions between cardiac muscle cells that allow for rapid electrical impulse transmission and coordinated contraction.
