corticobulbar
what artery?
most or all of the occipital lobe- - Answer✔posterior cerebral artery
what artery?
the area surrounding the lateral (or sylvian) fissure - Answer✔middle cerebral artery
what artery?
the brainstem - Answer✔basilar artery

Which of the following pathways transmits sensation of pain and temperature? -
Answer✔anterolateral
What arterial structure is located at the base of the brain and serves as a safety mechanism? -
Answer✔circle of Willis

The boundary between the frontal and temporal lobes is the ___________ - Answer✔lateral
fissure
The central sulcus is the boundary between the frontal lobe and the [x] lobe. - Answer✔parietal
The two main structures of the central nervous system are the [x] and [p] - Answer✔brain
spinal cord
connect higher parts of the CNS to lower parts of the CNS - Answer✔projection fibers
connect two different areas of the same cerebral hemisphere - Answer✔association
connects an area in one hemisphere to the similar area in the other hemisphere -
Answer✔commissural
Which basal ganglia structure produces dopamine? - Answer✔substantia nigra

The primary somatosensory cortex is on the _________ gyrus of the _________ lobe -
Answer✔postcentral gyrus
parietal
The structure(s) of the motor system most strongly associated with involuntary movements
when damaged is/are the - Answer✔basal ganglia

reflexive rhythmic conjugate eye movements. The function of the vestibular reflexes is to
maintain a stable visual fixation point.
What is the significance of bilateral representation in the auditory system? - Answer✔the
multiple crossings of auditory information contribute to the bilaterality of cortical auditory
representation. The primary aud cortex in each hemisphere recieves input from both ears. If
there was a lesion on the aud pathway it would not result in complete hearing loss

Optic nerve- - Answer✔The fibers of the optic nerve come from one eye, in the chaism they
come from both eyes and in the optic tract.
