Properties of Muscles

-Excitable or Irritable: capable of receiving and responding to stimulations by nerves. Example A

-Contractible: capable of shortening. Example B

-Extensible: can be stretched without damage. Example C

-Elasticity: able to return to resting shape after being contracted or extended. Example D

-Adaptability: can change in response to how it's being used, get bigger or smaller. Example E

What are muscles made of?

Muscles are all made of the same type of tough and elastic tissue (sort of like the material in rubber bands). Muscles are located under our skin and cover our skeleton.

Skeletal Muscles:

Skeletal muscles are attached to the bones of your skeleton. Because you have conscious control of skeletal muscles, they are classified as voluntary muscles.

Skeletal Muscles:

These muscles provide the force that moves your bones. Skeletal muscles react quickly and tire quickly. At the end of a skeletal muscle is a tendon. A tendon is a strong connective tissue that attaches muscle to bone.

Smooth Muscles:

Smooth muscles are called involuntary muscles because they work automatically. They are inside many internal organs of the body, and control many types of movements inside your body, such as those involved in the process of digestion. Smooth muscles react more slowly and tire more slowly than skeletal muscles.

Cardiac Muscles:

Cardiac muscles are involuntary muscles found only in the heart. Cardiac muscles do not get tired.

Movement:

Muscles work by contracting, or becoming shorter and thicker. Because muscle cells can only contract, not extend, skeletal muscles must work in pairs.

Movement:

While one muscle contracts, the other muscle in the pair returns to its original length. For example, in order to move the lower arm, the biceps muscle on the front of the upper arm contracts to bend the elbow. This lifts the forearm and hand.

Movement:

As the biceps contracts, the triceps on the back of the upper arm returns to its original length. To straighten the elbow, the triceps muscle contracts while the biceps returns to its original length.
