Types of muscle Flashcards
What are the three types of muscle?
Skeletal muscle
Cardiac muscle
Involuntary muscle
What are skeletal muscles responsible for?
Name two examples
Movement
Bicep
Tricep
What are the cardiac muscles responsible for?
Only found in the heart
Myogenic
What are the involuntary muscle responsible for?
Lining of organs such as the stomach and bladder
What is the fibre appearance of skeletal muscle?
Striated
What is the fibre appearance of cardiac muscle?
Specialised striated
What is the fibre appearance of involuntary muscle?
Non-striated
What is the control of skeletal muscles?
Voluntary
What is the arrangement of skeletal muscle?
Regularly arranged so muscle contracts in one direction
What is the arrangement of cardiac muscle?
Cells branch and interconnect resulting in simultaneous contraction
What is the arrangement of involuntary muscle?
No regular arrangement - different cells can contract in different directions
What is the contraction speed of skeletal muscle?
Rapid
What is the contraction speed of cardiac muscle?
Intermediate
What is the contraction speed of involuntary muscle?
Slow
What is the length of contraction for skeletal muscle?
Short
What is the length of contraction for cardiac muscle?
Intermediate
What is the length of contraction for involuntary muscle?
Relatively long
What is the structure of skeletal muscle?
Cross striations
Tubular
Uninucleated
What is the structure of cardiac muscle?
Faint striations
Branched
Uninucleated
What is the structure of involuntary muscle?
No cross striations
Spindle shaped
Uninucleated
