What are the bundles of Muscle Fibers called? A. Myofibrils B. Striation C. Sarcolemma D. Fascicles |
D. Fascicles |
|
|
In a muscle cell, the plasma membrane is called the __________. |
Sarcolemma |
|
|
What is the layer of connective tissue that covers the fascicles? A. Endomysium B. Epimysium C. Perimysium D. Muscle Belly |
C. Perimysium |
|
|
The _________ is a part of the __________ which is a part of the ________ makes up the muscle belly |
Myofibril, sarcoplasm, Fascicle |
|
|
Explain the functions of the Epimysium. |
The Epimysium is a thick layer of connective tissue that thickens as it reaches the end of the muscle to make a tendon which attaches onto the bone. |
|
|
Skeletal muscles are what type of cells? A. Cardiac B. Muscle C. Nerve |
B. Muscle |
|
|
What is the theory of how Muscles contract called? |
The Sliding Filament Theory |
|
|
Explain the Sliding Filament Theory |
This Theory involves the myofilaments sliding across each other which causes of sarcomere to shorten in length, thus shortening the muscle |
|
|
What does the Sarcoplasm contain? |
Mitochondria, myoglobin (the muscle's equivalent to haemoglobin), fat, glycogen, creatine phosphate, adeonsine triphosphate (ATP), enzymes and myofilaments |
|
|
Each muscle fibre is made up of __________ |
Myofibrils |
