|
|

They are muscles that we have no conscious control over. |
|
|
Name three types of muscle. |
Smooth muscle Cardiac muscle Skeletal muscle |
|
|
explain the difference between the three types of muscle. |
Smooth muscle is involuntary and found in organs. Cardiac muscle is found in the heart and is also involuntary. Skeletal muscles attach to bone to cause movement and can be consciously controlled. also have reflex action. |

|
What are the three types of muscle contractions? |
Isometric contractions Isotonic contractions Isokinetic contractions |
|
|
which contractions changes the length of a muscle? A: Isokinetic B: Isoquadric C: Isometric D: Isotonic |
D: Isotonic |

|
There are four types of skeletal muscle. Name three of them. |
Fusiform Bipennate Multipennate Unipennate |
|
|
Fusiform muscles are ________ shaped. An example of a fusiform muscle is the _________. |
Spindle. Biceps brachii. |
|
|
What are bipennate muscles. Give an example |
They are muscles that have two rows of muscle fibers. Rectus femoris. |
|
|
What is the defining feature of Multipennate muscles |
The defining feature of multipennate muscles are their multiple rows of diagonal muscle fibers. E.g. Deltoid, it has three sections: anterior posterior and middle. |
