Are smooth muscles striated?
200
Location: Heart Function: Propel blood throughout body.
What is the location and function of cardiac muscle?
200
Increase: Hypertrophy Decrease: Atrophy

How are cardiac muscles connected?
300
Action Potential
What is the rapid depolarization and repolarization of a cell membrane called?
400
Heat is given off
What is the effect when skeletal muscles contract?
400
the lag phase
What is the time between the application of a stimulus and begining of contraction called?
400
Location: Wall of hollow organs, blood vessels, and glands. Function: Compression of organs, ducts, tubes, etc.
What is the location and function of smooth muscle?
400
Neurotransmitters
What stimulates contraction in cardiac muscle?
400
ATP is not available after you are dead and so the cross bridges that are formed can not release the contraction
What is the cause for rigor mortis?
500
Body Movement, Maintenance of posture, Production of body heat, Communication, Constriction of organs and vessels, and Heart beat.
What are the 7 functions of the muscular system?
500
contractility, excitability, extensibility, and elasticity
What are the 4 major functional characteristics?
500
smooth muscle functions as a unit and contracts at the same time.
What is special about how smooth muscle functions?
500
contraction is sustained by aerobic metabolism.
Why doesn't cardiac muscle fatigue?
500
sternocleidomastoid
