What are the properties of muscle tisse?
1. Excitability - nerve signals excite muscle cells an dcause contration
2. Contractility - Myofilatments allow for contractile force to occur.
3. Elasticitiy - After being stretched, muscle tissue recoils passively
4. Extensibility - muscle tissue can be streched - the contraction of a muscle means another muscle is acting in the opposite force.
What are the functions of muscle tissue?
1. produce movement
2. open and close body passageways
3. maintain posture and stabalize joints
4. generate heat.
What are the three types of muscle and where are they found?
1. Skeletal - attach to and move the skeleton. Voluntary, striated, multinucleate.
2. Cardiac - Heart, striated, monounucleate, involuntary.
3. Smooth - hallow internal organ walls (other than heart), non striated, mononucleate, involuntary.
What is the epimysium?
The outter layer of DENSE IRREGULAR CONNECTIVE TISSUE that surround the WHOLE SKELETAL MUSCLE. the name means - outside muscle.
