What is a Skeletal Muscle?
Muscles that are attached to bones and skin.
What is Cardiac Muscle?
Muscle tissue that is only found in the heart.
What are Fascicles?
Groups of muscle fibers
What is the most powerful kind of muscle cell?
Skeletal muscles
What type of muscle cells can be controlled manually?
Skeletal
What is a Muscle Fiber?
Muscle cells that are elongated.
What is Smooth Muscle?
Muscle tissues is found in walls of hollow organs.
What is a Contraction?
The activation of cross bridging to generate force
What kind of muscle cells contract the Fastest?
Skeletal
What types of muscle cells CANNOT be controlled manually?
Cardiac and Smooth
What are Muscles?
Highly specialized biological tissues characterized by its ability to convert chemical energy into mechanical energy.
What is Contractility?
Ability to shorten forcibly when stimulated
What is a Concentric Contraction?
Contraction where muscles shorten and do work
What are the three kinds of muscle cells?
Skeletal, Cardiac, and Smooth
What kinds of muscles cells are the largest in size?
What is Extensibility?
Ability to be stretched
What is Excitability?
Ability to receive and respond to stimuli
What is a Eccentric Contraction?
Contraction where the muscle lengthens and generates force
What kinds of muscle cells are striated?
Skeletal and Cardiac
Why do skeletal muscles need a large blood supply?
So blood can carry in oxygen and carry out waste materials.
What is Elasticity?
Ability to recoil to resting length
What is an Isometric Contraction?
Contraction where there is no shortening; muscle tension increases but does not exceed load
What is an Isotonic Contraction?
Contraction where muscle shortens because muscle tension exceeds load
What are the four functions of your muscles?
Produce movement, maintain posture and body position, stabilize joints, and generate heat.
What are the three main features that all skeletal muscles have?
Nerve and blood supply, connective tissue sheaths, and attachment points.
