Reorder the following from largest (1) to smallest (5)
Muscle
Muscle Fascicle
Muscle Fiber
Myofibril
Myofilaments
What are tendons?
Connects bones to muscles
Connects bones to bones
Connects cartilage to bone
Connects ligaments to muscle
Match the definitions to the terms.
A contractile unit of a muscle fiber
Sarcomere
A muscle cell
Muscle Fiber
Protein filament
Actin and Myosin
Calcium storage
Sarcoplasmic Reticulum
Muscle cell membrane
Sarcolemma
Reorder the following to explain how muscle contraction and relaxation occurs:
An electrical signal travels down the muscle fiber through Transverse-tubules
Calcium is released from sarcoplasmic reticulum
Calcium and ADP cause the Myosin head to bind to the Actin filament
Muscle contracts and Z-lines are brought closer together (shortening the muscle)
ATP releases the myosin head from the Actin, leading to muscle relaxation
When a muscle contracts, it ____________
gets longer
gets shorter
gets thinner
grows hair
