A neurotransmitter that stimulates skeletal muscles
acetylcholine (Ach)
ATP
cross bridges
neuromuscular junction
What is the function of Calcium during a skeletal muscle contraction?
connects to H zone to close binding sites
connects to actin to open binding sites
connects to myofibril to form a cross bridge
connects to myosin to open binding sites
The Sliding Filament Theory states that
contraction occurs due to the shortening of thick filaments
contraction occurs due to the shortening of thin filaments
contraction occurs due to the sliding of thin filaments past thick filaments
contraction occurs due to the "accordian-like" folding of thick and thin filaments

True
False

Mg+
Na+
Cl-
Ca+
Which of the following ions are responsible for creating the "action potential" in the neuron and in the membrane of the muscle fiber? Choose all that apply.
Na+
K+
Ca++
Mg+
Which of the following ions plays a key role in the release of the neurotransmitter from the motor neuron AND signaling the start of the muscle contraction?
Ca++
Na+
K+
Mg+
