Motor Unit Function — Flashcards
The maximum contractile force of any muscle per square cm cross-sectional area is _____ kg/cm2
Slow twitch muscle fibers are _____ due to increased myoglobin concentration
Hint: (color)
In the muscle stretch reflex, stretch increases afferent impulses via _____ and II nerve fibers
Fast twitch muscle fibers perform less _____ due to decreased mitochondria
Stretch reflex:Activation of _____ motor neurons leads to direct contraction of the muscle
Which nerve fiber afferents innervates all three muscle spindle fibres (dynamic nuclear bag, static nuclear bag, and nuclear chain fibers)?_____
The first step of muscle contraction occurs when the _____ neuron depolarizes, opens Ca2+ channels and ACh is released into the motor end plate.
A mass of many smooth muscle fibers contract together in _____-unit smooth muscle system
Chemical Events during Muscle Contraction: The **power stroke** is initiated by the release of _____ from the myosin head.
_____ is absent in smooth muscle but present in skeletal muscle
Hint: Micro-component
