Verified Answers.
ipsi-lateral vs. contra-lateral correct answers connecting to the SAME side vs. connecting to the
OPPOSITE side
lateral vs. medial correct answers towards the sides vs. towards the middle
ventral vs. dorsal correct answers towards the stomach or bottom of the human head vs. towards
the back or top of the human head
superior vs. inferior correct answers a structure above another vs. one below another
coronal vs. sagittal vs. horizontal correct answers planes through head as seen from the front vs.
the side vs. above/below
diencephalon correct answers division of the forebrain that ultimately becomes the thalamus,
hypothalamus, and the eye
telencephalon correct answers division of the forebrain that ultimately becomes the cerebral
cortex, basal ganglia, limbic system, etc.
medulla correct answers hindbrain structure, controls vital reflexes
pons correct answers hindbrain structure, acts as a bridge between hindbrain and higher centers
cerebellum correct answers hindbrain structure, involved primarily with guided, timed
movements
reticular formation correct answers network of cells moving medially through hind and mid
brain, involved in arousal
raphe system correct answers core strip of cells through hind and mid brain, involved in sleep
tegmentum correct answers midbrain structure involved in motor processes
tectum correct answers midbrain structure involved in sensory processes, incldues superior
(visual) and inferior (auditory) colliculi
hypothalamus correct answers forebrain structure, oversees 4 Fs (fight, flight, feed, f*ck),
temperature, clock; communicates with and through the endocrine system
pituitary gland correct answers forebrain structure; "master gland," stimulated by hypothalamus
, thalamus correct answers forebrain structure, a principal stop along most sensory, motor and
arousal pathways, projects to cortex
limbic system correct answers a set of forebrain structures involved in motivation and emotional
expression
hippocampus correct answers Part of above system, involved in the formation of new memories
amygdala correct answers part of above system, associated especially with anger and fear, also
with recognizing emotions of others
cingulate gyrus correct answers part of above system, re-entrant layer mediating between cortex
and lower systems, especially for +/- evaluation
olfactory bulb correct answers part of above system, receives smell info from olfactory receptors
basal ganglia correct answers forebrain structure including caudate nucleus, putamen and globus
pallidus, involved in organization of movement sequences
basal forebrain correct answers forebrain structure including nucleus accumbens, involved in
arousal of cortex, attention and reinforcement
cerebral cortex correct answers forebrain structure, outer "bark" of brain, 6 layer, highly
convoluted
occipital lobe correct answers lobe of the cortex, posterior, primarily involved in visual
processing including V1 (striate cortex)
temporal lobe correct answers lobe of the cortex, lateral, primarily involved in auditory
processing (e.g. A1 and Wernicke's) and higher visual (IT)
parietal lobe correct answers lobe of the cortex posterior to the Central Sulcus, primarily
involved in somatosensory and visuo-spatial mapping
frontal lobe correct answers lobe of the cortex anterior to Central Sulcus, including motor and
premotor areas (including Broca's and mirror Cells)
prefrontal cortex correct answers most anterior part of above lobe, involved in self control,
strategy, cultural rules, etc.
cranial nerves correct answers 12 pairs of sensory and motor nerves sending messages in and out
of brain
spinal cord correct answers part of the CNS other than the brain
