Exam 12: Muscle: Mechanisms of Contraction and Neural Control

The biceps brachii causes flexion of the elbow.The triceps brachii causes extension of the elbow,so it would be a/an

Myostatin is

The specialized region of the sarcolemma at the neuromuscular junction is called the

A muscle contraction against a resistance that is greater than the force and causes muscle lengthening is a(n)

Exceeding the VO_2max will result in lactate production by the muscle.

What protein primarily makes up the thick filament?

Increasing the frequency of action potentials in a somatic motor neuron will induce increased force of muscle contraction.

The actin filament is a polymer formed from 300 to 400 globular subunits called

The _________ complex contains three proteins designated as the I,T,and C types.

Motor unit recruitment allows for _________ contraction strength.

Insertion of ______________ in the muscle cell membrane increases cellular glucose uptake.

Type I skeletal muscle fibers

Shaking of limbs at rest that disappears during voluntary movement due to damage to the basal nuclei is called

Muscle hypertrophy is due to

Which of the following does NOT increase the strength of the muscle contraction?

What muscle structural and functional unit runs from Z disc to Z disc?

Each somatic motor neuron with all the muscle fibers it innervates is a

Which of the following does NOT occur during the cross bridge cycle?

Central fatigue is caused by

Fatigue appears to occur due to the reduced ability of the sarcoplasmic reticulum release of Ca²⁺ with neural stimulation.
