Muscle Act pt 2

Muscles Activity Pt 2

Muscle actions only Pull
Muscle movements appear to be smooth because of Graded muscle responses.
In muscle movement, when action is just starting, it is called the Latent Period
The body contains 640 Skeletal Muscles
When a muscle contracts, the bone that moves is called the Insertion Point
Stabilizing joints against dislocation is the job of Synergists
A group of muscles fibers that all get their signals from the same, single motor neuron is called a Motor unit
Lifting a mug of coffee is an example of Isometric movement
The insertion bone is always pulled toward the Origin Bone
When fibers quickly contract and release, it is called a Twitch
