Introduction
All movements performed by muscles. .
voluntary muscles : skeletal m’s.
involuntary muscle. .(heart ms, respiratory ms)

Types of Muscle tissue
The muscle fibers. They can contract , which
means they can shorten their length.
Muscle fibers form three types of muscle tissue:
1-cardiac .
2- visceral :
3- skeletal .

All muscle is wrapped in a band of connective tissue called
fascia , This is called deep fascia.

Movements of Skeletal
Muscles
All skeletal muscles are connected to two bones.
This makes movement possible..
The muscles are connected to bones by bands of
connective tissue.
Some of these tissues are thin and cordlike. They are
called tendons .
Broader bands of connective tissues are called
aponeuroses .
