FROM 3d TO THE 4TH VENTRICLE describe CSF functions - Answer--current carries signals for sleep, appetite, sex -provides nutrients -flushes harmful substances out of CNS what controls circadian rhythms? - Answer-Suprachiasmatic nuclei what is associated with elderly dementia (alzheimers) - Answer-choroid plexus calcification what surrounds and protects the CNS? - Answer-meninges what lines the cranial cavity forming the periosteal covering for the inner aspect of the bones? - Answer-outer layer of the dura mater what extends through the sutures to become the periosteum on the outer surface of the skull? - Answer-outer layer of the dura mater what covers the CNS and has reduplications: the falx cerebri and the tentorium cerebelli? - Answer-The inner layer of dura mater what does 'primary' refer to in PRM? - Answer-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? - Answer-refers to the exchange of gases and metabolites at the cellular level what is implied by the 'mechanism' in PRM? - Answer-implies an integrated machine what are the five anatomic-physiologic components of PRM? - Answer-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 - Answer-Subtle, slow, wormlike movement Rhythmic, biphasic cycle describe the Fluctuation of the CSF - Answer--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 - Answer-lateral and 3rd ventricles aquaduct of sylvius foramen of magendie what form the intradural sinuses? - Answer-Sickle-shaped structures arising from the straight sinus, fused in certain areas and separated in others The dura and its reduplications along with the motility of the CNS and fluctuation of the CSF form the anatomical unit known as? - Answer-the reciprocal tension membrane (RTM) what is a core link that transmits forces by linking the cranium to the sacrum? - Answer-the RTM describe venous circulation - Answer-superior sagittal sinus, inferior sagittal sinus, lateral/transverse sinus, straight sinus what is the "pump" for the CSF and venous systems? - Answer-cranial sacral motion what is of paramount importance during birth? - Answer-Articular Mobility of the Cranial Bones what causes the sacrum to involuntarily move in response to the CRI along the Superior transverse axis? - Answer-dural attachments/RTM what is a system that stabilizes itself mechanically because of the way in which tension and compression forces are distributed and balanced within the structure? - Answer-tensegrity (self correcting structure) what are Dr. Still's Basic Principles? - Answer-The body functions as a unit The body possesses self-regulatory mechanisms Structure and function are reciprocally interrelated what are some functions of glia? - Answer--glia nurture and defend the neuron -rein in neurons' impulses, shape their future moves which cells have an insulating role in the brain? - Answer-oligocytes which cells engulf and dispose of threatening viruses and bacteria in the brain? - Answer-microglia which cell composes 90% of glia? - Answer-astrocytes which cells may play a role in learning and memory processes? - Answer-astrocytes how do PRM impulses move in midline structures? - Answer-flexion/extension how do PRM impulses move in paired structures? - Answer-external/internal rotation
