29
3rd ventricle found where
between the hypothalamus
30
traverses the tegmentum of the midbrain
cerebral aqueduct of sylvius | --connects 3rd and 4th ventricles
31
derived from plasma and fills the ventricles
CSF
32
dilated portion of subarachnoid space located anterior to pontomedullary junction
prepontine cistern
33
expanded portion of arachnoid space named after structures adjacent to them
cisterns
34
surrounded by subarachnoid space: spinal cord, brain, intracranial part of cranial nerves, intravertebral part of spinal nerves?
ALL
35
arises from vertebral artery
``` posterior inferior cerebral artery (PICA), posterior spinal artery (PSA), anterior spinal artery , medullary artery, basilar artery ```
36
blood supply of the insular lobe
middle cerebral artery
37
middle cerebral artery
``` Largest branch of ICA o Runs laterally passing through the Lateral Sylvian Sulcus o Territorial Supply: • Lateral Frontal Lobe • Lateral Parietal Lobe • Anterior Temporal Area • Insula • Lentiform and Caudate Nuclei • Internal Capsule ```
38
territorial supply of anterior cerebral artery
* Medial Portion of the frontal lobe * Superior Medial Parietal Lobe * Lentiform Nucleus * Caudate Nucleus * Internal Capsule
39
posterior cerebral artery
o Inferolateral and Medial Surface of the Temporal Lobe | o Occcipital Lobe
40
confluence of sinuses =
straight + superior + occipital
41
straight sinus =
superior sagittal + inferior sagittal
42
drains the insular lobe
deep middle cerebral vein
43
drains in the superior sagittal sinus
superior cerebral vein
44
drains into the cavernous sinus
superficial middle cerebral vein
45
empty in the Great Cerebral Vein of Galen
basal vein of rosenthal
46
sensory homonculus
bigger lips
47
motor homonculus
bigger face and hands
48
area 32 & 33
anterior cingulate cortex hypostimulation: low attention span hyperstimulation: ADHD
49
hemineglect can be seen among patients with lesion affecting
right primary somatosensory area
50
lesion on right area 312 will result in
sensory deficit on the left upper extremity
51
gyrus surrounding the parieto-occipital fissure
primary visual cortex
52
axons from ventral posterolateral nucleus of the thalamus will project to what part of the cerebral cortex
area 312
53
anterior hypothalamus
lowers body temp
54
posterior hypothalamus
increases body temp
55
VPL
pain or temp, neck below
56
VPM
head and neck and taste
57
VPL connections - afferent:
Medial and Spinal Lemniscus (tracts in the brainstem carrying
58
VPM connections - afferent:
Afferent – Trigeminal Lemniscus, | Gustatory fibers
59
damage to the subthalamic nucleus will result to a condition known as
hemiballismus of the CONTRALATERAL side
60
separates the medial and lateral groups of hypothalamic nuclei
mamilothalamic tract; fornix
61
controls the sleep wake cycle
suprachiasmatic hypothalamic nuclei
62
oxytocin is expressed by which hypothalamic nuclei
paraventricular
63
antidiuretic is expressed by which hypothalamic nuclei
supraoptic
64
defining anatomical feature of caudal midbrain
inferior colliculus
65
defining anatomical feature of the rostral medulla
olive
66
brainstem nuclei that receive general somatic afferent information
mesencephalic nucleus of CN V
67
has both somatic motor and parasympathetic components
occulomotor nerve
68
principal site at which integration of sensory info regarding the cardiovascular and respiratory system is located
nucleus solitarius
69
occulomotor nerve
- axons terminate in the levator palpebrae superioris - axons terminate in the medial rectus muscle - lesion results in double vision when the ipsilateral eyelid is raised - axons travel through the cavernous sinus
70
diplopia is always present except when ask to gaze to the contralateral side of the lesion
abducens
71
right hypoglossal nerve
tongue will deviate towards the right
72
nucleus tractus is shared by these cranial nerves
VII, IX, X
73
dorsal motor nucleus is shared by which CN
CN X
74
damage to the right edinger westphal nucleus will result in
loss of direct and consensual light reflex on right eye
75
corneal reflex controlled by
trigeminal and facial nerves
76
trigeminal nerve
the main motor nuclei of CN V is located in rostral pons
77
lesion involving the facial nerve distal to its exit to stylomastoid foramen will result in...
ipsilateral facial paralysis, both upper and lower quadrant.
