Actions of Muscles

Muscles can only pull, they cannot push
-what one group does, another group undoes

6

Synergist

Helps prime movers
Adds extra force to same movement
Reduces undesirable or unnecessary movement

7

Naming Skeletal Muscle

Location of Muscle
Shape
Size
Direction of muscle fibers
Number of Origins
Location of Attachment
Muscle Action

8

Arrangement of Fascicles

Circular- rings
Convergent- broad origin, single tendon insertion
Parallel- strap-like, parallel to long axis
Fusiform- spindle-shaped muscles with parallel fibers
Pennate- short fascicles attach to central tendon running length of muscle

9

Lever Systems

Lever- bone
Effort- force
Load- resistance
