| Question | Answer |
|---|---|
| The fibrous connective tissue that surrounds the entire muscle and is outside the epimysium and tendon is called the | fascia |
| The muscle that helps hold the scapula against the thorax and is useful in pushing or punching movements is the | serratus anterior |
| Muscles that move the forearm include which of the following? | brachioradialis, pronator teres, biceps brachii |
| The individual muscle fibers are covered by a connective tissue membrane called the | endomysium |
| A muscle with fascicles that insert into the tendon from both sides is categorized as | bipennate |
| The Sartorius muscle, a thin strap like muscle would have muscle fascicles arranged in | parallel |

| In addition to the Pectoralis major, another muscle that displays this pattern of fascicle arrangement is Latissimus dorsi. | convergent |
| The term _____ is used to describe a muscle that directly performs a specific movement. | agonist |
| Muscles that move the wrist, hand, and fingers can be | extrinsic or intrinsic |
| A muscle with fascicles that insert into only one side of the tendon is categorized as | unipennate |
| The continuous low level of sustained contraction maintained by all skeletal muscles is muscle | tone |
| The biceps brachii has this fascicle arrangement, which maximizes the range of motion possible. | parallel |
| The biceps brachii has this fascicle arrangement, which maximizes the range of motion possible. | calcaneal tendon |
| The long axes of the fascicles run parallel to the long axis of the muscle is a description of this type of fascicle arrangement. | parallel |
| The muscle fascicle arrangement for Orbicularis oris is best characterized as | circular |
| Muscles with this type of muscle fascicle arrangement are either fusiform or strap like in appearance. | parallel |
| An example of a muscle with this type of fascicle arrangement is the orbicularis oris. | circular |
| An example of a muscle with this type of fascicle arrangement is the orbicularis oris. | transverse abdominis |
