Muscle Histology Flashcards
What are the muscle tissue types
Skeletal
Cardiac
Smooth
What can you find in cardiac muscle
Intercalated discs
Where can you find smooth muscles
Hallow organs
What do intercalated discs have and look like
Membrane junctions and they look like a break in the muscles
What do skeletal muscles do that all other muscles do not do
Volentary movement
What is the outside of the skeletal muscle
Epimysium
What are inside the epimysium
The fascicle
What is the outer layer of the fascicle?
Perimysium
What surrounds the myofiber?
Endomysium
What is inside the muscle fascicle
Myofibers
What attaches a muscle to a bone?
Tendon
What is the aponeuroses?
Connective tissue that cover your muscles
What are agonists
Prime moving muscles
What does the opposite movement of an agonist?
Antagonist
What are two types of skeletal muscles that work opposite to each other?
Agonist and antagonists
What is the helper of the agonist
Synergists
What do synergists do?
Help agonist with muscle movement
What are fixators?
Muscles that keep bones in place
What is an example of a fixator?
Shoulder muscles
What is an origin?
A bone marking that does not move
What is an insertion?
A bone marking that moves
