Location in the body:
Attached to skeleton
Other features:
Voluntary control

4. Cardiac Muscle Description: Function: Locations in the body:
Striated
Uninucleate (1 nucleus)
Branching cells – fit at junctions called intercalated discs
Function:
Propel blood through blood vessels to all parts of body
Locations in the body:
Walls of the heart
Other features:

6. Smooth Muscle Description: No visible striations 1 central nucleus
