Lecture One Flashcards
What is defined as the ability to maintain and change posture and movement is the result of a complex set of neurologic and mechanical processes.
Motor Control
Which treatment theory is top-down and emphasizes the integration of reflexes.
Hierarchical Theory
What are the three primitive reflexes?
Rooting, Palmar and Plantar Support
What are the three tonic reflexes?
ANTR, STNR, TLR
When are most reflexes (primitive and tonic) integrated?
4-6 months
Name two ions involved in generating an action potential
Sodium (Na+) and Potassium (K)
Is the corticospinal tract ascending or descending
descending
Where is the motor cortex
Back of the frontal lobes
What is the resting membrane potential of most neurons
-70mV to -90mV
What is called when an action potential jumps at gaps in the myelin sheath
saltatory conduction
Where do most corticospinal tracts cross-over
Megalta Obligato
Where do the spinothalamic tracts end
Somatosensory Cortex
What are the three phases of motor learning
Cognitive, Associative, Autonomous
Which phase of motor learning involves practicing but still making mistakes
Associative
In the systems model, which sway strategy is used first for postural control
ankle
