origin, insertion
This is an inflammation of the synovial membrane surrounding a joint:
A lever is acted on at two different points by two different forces that are
effort and load
Motion will occur in a muscle when the _____ supplied exceeds the _____.
effort, load
Which of the following is not a fascicle arrangement?
pennate, circular, fusiform, parallel (all are)
This type of fascicle arrangement has the fascicles spread over a broad area and converges at a thick central tendon.
What is another name for a prime mover?
This type of muscle works by stabilizing the origin of a prime mover so that it can act more efficienty.
Which of the following is NOT one of the descriptive ways to name a muscle?
number of cells
Tendinitis of the tibialis anterior can result in a painful condition commonly known as:
The attachment of a muscle to the more stationary bone is the:

range of motion
Muscles that hold the scapula firmly in place with the forearm moves are called the:
An adductor muscle:
moves a part of the body toward the midline
Severing the patellar tendon would inactivate the hamstring group of muscles.
The arrangement of muscles fascicles determine its range of motion and power.
Muscles are only able to pull, they never push.
Regardless of type, an effort farther than load form fulcrum equals a mechanical advantage whereas an effort nearer the load to fulcrum equals a mechanical disadvantage.
The deltoid is a prime mover of the arm that acts in adduction
