Students have asked these similar questions
(a) Describe the roles of ATP in the sliding filament mechanism of skeletal muscle contraction.
(b) Describe the basic sequence of events that occurs as an action potential arrives at the neuromuscular junction and is transmitted to the muscle cell for contraction.
The greater the number of _________ involved in a motor unit, the ________ the degree of fine muscle control.
Question 9 options:
a)
muscle fibers............less
b)
ligand gated channels………….less
c)
layers of epimysium.........less
d)
muscle fibers............greater
A muscle that helps an agonist by causing a similar movement or by stabilizing a joint over which the agonist acts is (a) an antagonist, (b) a prime mover, (c) a synergist, (d) a fulcrum.
