PRM QUESTIONS AND ANSWERS
What does 'primary' refer to in PRM? - Answers - refers to its importance
The physiologic centers that control respiration, circulation, digestion, and elimination
are located in the floor of the fourth ventricle and depend on the function of the CNS
What does 'respiratory' refer to in PRM? - Answers - refers to the exchange of gases
and metabolites at the cellular level
What is implied by the 'mechanism' in PRM? - Answers - implies an integrated
machine
What are the five anatomic-physiologic components of PRM? - Answers - Inherent
Motility of the Brain and Spinal Cord
Fluctuation of the CSF
Mobility of the Intracranial and Intraspinal Membranes
Articular Mobility of the Cranial Bones
Involuntary Mobility of the Sacrum between the Ilia
Describe the Inherent Motility of the Brain and Spinal Cord - Answers - Subtle, slow,
wormlike movement
Rhythmic, biphasic cycle
Describe the Fluctuation of the CSF - Answers - -rate is 10-14 cycles per minute
-CSF found in the choroid plexus
-CNS goes thru biphasic rythym + ventricles change shape+ CSF fluctuation = CRI
Describe CSF circulation - Answers - lateral and 3rd ventricles
Aquaduct of sylvius
Foramen of magendie
What can the aqueduct by impacted by? - Answers - SBR-kinks it
Torsion-twists it
Flexion/extension-kinks it
Extreme extension-stretches it
Aqueduct passing over the s/b area can cause disruption of flow where? - Answers -
DISRUPTS FLOW OF C.S.F. FROM 3d TO THE 4TH VENTRICLE
Describe CSF functions - Answers - -current carries signals for sleep, appetite, sex
-provides nutrients
-flushes harmful substances out of CNS
What controls circadian rhythms? - Answers - Suprachiasmatic nuclei
