MUSCLE TISSUE Flashcards
What are the two characteristics of muscle tissue?
- Elongated cells
- Specialized to contract (shorten) and generate force (action)
What are the three types of muscle tissue?
- Skeletal
- Smooth
- Cardiac
What are the three characteristics of skeletal muscle?
- Attaches to bones
- Striated - show pattern of bands
- Voluntary contraction
What are the three characteristics of smooth muscle?
- Associated with viscera (organs)
- Non-striated
- Involuntary contraction
What are the three characteristics of cardiac muscle?
- Found only in the heart
- Striated - show pattern of bands
- Involuntary contraction
What do skeletal muscle form?
Long, cylindrical, multi-nucleated tubes
What do skeletal muscle exhibit?
Distinct cross-banding patterns
What do skeletal muscle stabilize and move?
Articulated skeleton
What is the structure of smooth muscle?
Cells short, spindle-shaped and contain a single nucleus (non-striated)
What does the smooth muscle form?
Walls of blood vessels and hollow organs
What are smooth muscle specialized for?
Slow sustained contractions
What is the structure of cardiac muscle?
Cells short, branches, striated and contain single nuclei
