Muscular System Flashcards
muscle attachment sites:
Which muscle is attached to a stationary bone
Origin
muscle attachment sites:
Is a thick midsection of the muscle
Belly
coordination among muscle:
major responsible for a certain movement
Prime mover
coordination among muscle:
Muscle that assist
Synergist
coordination among muscle:
Muscles that reverse a prime mover
Antagonist
isotonic and isometric contractions:
The contractions which the tension in muscles remains the same and muscle shortens
Isotonic contractions
isotonic and isometric contractions:
The contractions which the tension in muscles increases and muscle does not shorten
Isometric contractions
Types of isotonic contractions:
As muscle shortens, it generates enough force to move an object
Concentric isotonic
Type of isotonic contractions:
length of muscle increases during contraction
Eccentric contractions
Identify the body movement:
Decrease in angle between arculating bones
Flexion
Identify the body movement:
Increase in angle between articulating bones
Extension
Identify the body movement:
Extension beyond anatomical position
Hyperextension
Identify the body movement:
Bone revolves around its own … axis
Rotation
Identify the body movement:
Away from midline
Abduction
Identify the body movement:
Movement of distal end of a body part in a circle
Circumduction
enumerate the function of the muscular tissue
movement of the body
stabilizing body positions
generating heat
communication
storing and moving the substances within the body
identify the function of muscular tissue:
walking or running
movement of the body
identify the function of muscular tissue:
skeletal muscle contracts = stabilizes yr joints + maintain body position
stabilizing body positions
identify the function of muscular tissue:
muscular contracts thus they generate heat (called thermogenesis)
generating heat
identify the function of muscular tissue:
muscle moves according to stimulus (action potential)
communication
identify the function of muscular tissue:
cardiac muscles contracts, pumps blood from heart to other parts of the body
and
sphincters contracts to prevent the outflow of contents from hollow organs
storing and moving substances within the body
what are sphincters
ring like bands of smooth muscles
what is the cell shape of smooth muscular tissue
spindle-shaped
what is the cell shape of cardiac muscular tissue
cylindrical
branched
