A&P 2.16 Action Potential

Horizontales
What is the brief period of time after an action potential begins, that a muscle fiber or neuron cannot conduct another action potential
TFL crosses the hip anteriorly causing what action
Local depolarization; a subthreshold stimulus generates this membrane potential
What kind of rotation happens when TFL brings the lateral tibia toward the ASIS
What kind of feedback mechanism describes conduction propagation
Aka "conduction"; the positive feedback mechanism describing nerve impulses communicating information from one part of the body to another, starting where they arise
The small superficial muscle located on the lateral upper thigh
During an action potential what term describes the membrane voltage coming down below the original resting membrane potential
Can a neuron receive enough excitation to send an impulse when its depolarized
Positive cell membrane on the outside, negative on the inside
Can a neuron receive enough excitation to send an impulse when its in the refractory period
What level of depolarization needs to be met before an action potential can be generated
Of the 2 main phases of an action potential, which one has a negative membrane potential on the inside, reaches zero, and then becomes positive; a change in the charge difference of a cell membrane
Which surface of the asis and iliac crest does TFL start
Verticales
Which conduction moves along an unmyelinated axon, ionic currents flow across each adjacent segment of the membrane
Of the 2 main phases of an action potential, which one restores the membrane potential to its resting state
What kind of tilt does the reverse action of all hip flexors cause to the pelvis
Aka talocalcaneal joint; allows inversion and eversion
A spreading wave of depolarization that surrounds the entire plasma membrane
What structure is superficial to vastus lateralis, rectus femoris, rectus intermedius and biceps femoris; the insertion for tensor fascia lata
After an action potential, what is the name for the period when no stimulus can generate another action potential
TFL brings the lateral condyle of the tibia and head of the fibula away from the midline in the coronal plane causing what action
Which conduction involves "leaping" electric signals between successive myelin sheath gaps to allow for faster signal propagation
After an action potential, when a resting membrane potential is partially restored, what is the name for the period when a greater than usual stimulus could generate an action potential
What ions move into a cell during depolarization
