Kaplan and Sadock's Synopsis of Psychiatry 12th Edition Test Bank ( QUESTIONS WITH
COMPLETE SOLUTIONS)
George Engel - ANSWER-Modern psychiatrist who influenced the biopsychosocial approach
10^11 - ANSWER-number of neurons in the brain
10^12 - ANSWER-number of glial cells in the brai
Astrocytes - ANSWER-The most common type of glial cells - provide nutrition of neurons,
deactivation of some neurotransmitters, and integration with the blood-brain barrier
Oligodendrocytes and Schwann cells - ANSWER-Produce myelin around axons
-Oligodendrocytes- CNS
-Schwann Cells-PNS
Microglia - ANSWER-Act as phagocytes, eating damaged cells and bacteria, act as the brains
immune system - derived from macrophages
Light touch, pressure, pain, temperature, vibration, and proprioception - ANSWER-The six
somatosensory modalities
Pathway of somatosensory information processing - ANSWER-Somatosensory information - two
point discrimination, tactile sense (fine touch), vibratory sense, kinesthetic sense, muscle
tension, joint position sense - fasciculi gracilis and cuneatus - VPL nucleus of the thalamus -
Somatosensory cortex (Brodmann's areas 3,1, and 2)
Somatosensory information - pain, temperature, coarse touch, deep pressure - spinothalamic
tract - VPL, VPI, intralaminar nuclei of the thalamus - Somatosensory cortex, Prefrontal cortex,
Anterior cingulate gyrus, Striatum, S-11
Tactile agnosia - ANSWER-Clinical syndrome defined by the inability to recognize objects based
on touch, despite the primary somatosensory modalities being intact. Localized to the border of
the somatosensory and association areas in the posterior parietal lobe
Lines of a specific orientation - ANSWER-What the primary visual cortex responds to
Particular movements of lines and angles - ANSWER-What the secondary visual cortex responds
to
