100
I am known as the NMJ for short
What is the Neuromuscular Junction?
100
This structure allows Ca2+ into the sarcomere
What are t-tubes?
100
This is known as the thick filament
What is the Myosin?
100
This breaks down the neurotransmitter in the NMJ
What is acetylcholinesterase?
100
Transport that requires ATP
What is active transport?
200
In this zone actin is the only filament found
What is the Iband?
200
This protein binds with Calcium Ions
What is Troponin?
200
This filament extends from the z disc to the end of the Iband.
What is the Actin?
200
This is closed as Na+ leaves the muscle fiber.
Ca2+ channels
200
is important for a muscle contraction yet never enters the muscle fiber
What is acetylcholine?
300
in this zone both actin and Myosin can be found.
What is the A Zone?
300
I am responsible for depolarization.
What is Na+
300
During a muscle contraction, work is done against this protein's elasticity.
What is titin?
300
This is necessary for Myosin cross bridges to let go of the Actin binding sites.
What is ATP?
300
causes the myosin heads to go from relaxed to cocked
What is ATP?
400
I represent the area from one z disc to the next z disc.
What is the sarcomere?
400
How is Ions entering the muscle fiber different than when they leave?
Passive transport allows them to enter, while active is used to force them to leave.
400
This bundle of proteins hold myosin in place during a contraction.
What is the M-line?
400
I lengthen the sarcomere after the crossbridge are no longer attached to the Actin
What is the titin?
400
I describe how muscles shorten.
What is sliding filament theory?
500
My length remains unchanged during a muscle contraction
What is the A zone?
500
I am the region responsible for the lighter colored striations.
What is the I band?
500
This protein has the function of inhibiting a muscle contraction.
What is tropomyosin?
500
This is the cause of "riggor Mortis"
What is the need of ATP to release cross bridges
500
A muscle contraction is complete when these 2 zones are gone
What is the H zone and I band?
