Neurology (16%) Flashcards
Difference thresholds:
• depend on the energy necessary to stimulate a sensory receptor.
• are measured in Judgmental Normal Differences.
• occur when we can detect the change in the intensity of a stimulus.
• occur when we can first detect some stimulus.

Which of the following statements about the dura and meninges is incorrect?
• Pacchionian bodies are small arachnoid villi that allow the return of CSF to the vascular system
- Pia mater is delicate and firmly adherent to brain and spinal cord composed of flat cells and fibrous tissue. It closely follows the brain’s contour into the gyri and sulci
- Dura is formed by two layers in which the outer layer is the inner bones’ periostrum
- The dura is a tough fibrous tissue that covers the brain and has three dural infoldings, falx cerebri, tentorium cerebelli, and sella diaphragm
