What do we call a single muscle cell?
Fascicle
Perimysium
Myofibril
Muscle fiber
What is the name of the structure inside Muscle Cells that allows them to contract?
Fascicle
Myofibril
Perismysium
Z-line
What is the name for the structure inside of Myofibrils that is made up of Actin and Myosine
Fascicle
Myofibril
Dystrophin
Sacromere
What are the contracting proteins in Muscle Cells?
Dystrophin + Actin
Actin + Myosin
Dystrophin, Actin + Myosin
Dystrophin + Myosin
What is the function of Dystrophin?
Connect Sarcomeres to Muscle Cell Membrane
Connect Actin to Myosin
Connect the Myofibrils together
Allow for contraction
What happens when a DMD muscle cell moves/contracts?
Nothing
muscle cell membrane thinkens
Heart stops
Small tears/rips form in the muscle cell membrane
Which is TRUE about healthy muscle cells?
Calcium is inside the muscle cells.
Proteases are activated.
Creatine Kinase is inside the muscle cells.
Energy cannot be accessed/used.
What happens when DMD muscle cells tear?
Proteases are activated.
Calcium flows out of the cell.
Creatine Kinase flows into the cell.
Energy can finally be accessed/used.
Why do DMD muscle cells tear?
They have too much Dystrophin
They are lacking Dystrophin/Dystrophin is too short.
Dystrophin is too long.
Dystrophin tangles within actin and myosin.
Which of the following is TRUE in a DMD muscle cell
Activated Proteases produce more protein.
Energy is easily accessible for movement.
Cells cannot repair their tears/damage.
Cell membrane repairs itself immediately after tearing.
