excel sheet- brain Flashcards
amygdala what lobe is it in what is the blood supply
temporal anterior choroidal from the internal carotid
where is the putamen relative to the insular cortex
medial
The anterior choroidal artery is occluded
transient amnesia- supples hippocampus
what lobe is the olfactory bulb and tract in and what is it supplied by
frontal lobe ACA
what artery supplies the thalamus
striate arteries from MCA
what is the only part of the diencephalon that is visible in the uncut Brian
mammillary bodies
what can occur if the dorsal pretectal area is compressed by a pineal tumor or hydrocephalus
loss of consensual reflex due to damage to the posterior commissure
what does the infundibular stalk pass through to reach the pituitary
diaphragma sellae
what area of the medulla is an CVO organ and monitors and responds to blood contents, including toxins
area postrema
link the deep nuclei with their function
Dentate-planning/timing/skill - lateral hemisphere
Globose & Emboliform-posture/ muscle tone/ walking- paravermis
Fastigial-eye movement & balance- vermis
what is the function of the
vermis
paravermis
lateral hemisphere
vermis- balance (important to gait)
paravermis- limb coordination
lateral hemisphere- planning and exucuding of coordinate movements
what lobe contains the tonsils
posterior lobe
*tonsillar herniation just above the foramen magnum –> compression of medulla –> dec respiration.
LP in this PT = death
what is the function of the flocculonodular lobe
VOR
significance of the inferior orbital fissure
The infraorbital and zygomatic nn exit the PPF and enter the orbit by traveling through the inferior orbital fissure
what forms firm barriers within the skull that limit brain movement and can result in mass effect
the falx cerebri and the tentorium
what is the flow of csf
lateral ventricles ® interventricular foramina (of Monro) ® third ventricle ®cerebral aqueduct (of Sylvius)® fourth ventricle ® median and lateral apertures (foramina of Magendie and Luschka) ® subarachnoid space.
what does the anterior commisure connect
the olfactory and temporal regions
what structure connects the left and right LVs
septum pellucidum
what ventricle is at the level of the midbrain
cerebral aqueduct
where is the thrid ventricle in relation to the optic chiasm and the anterior commisure
above the optic chiasm and posterior to the anterior commisure
where is the fourth ventricle located
Between the dorsal pons and the cerebellum
what seperates the occipital lobe into first and second visual fields
calcarine sulcus
where is the superior and inferior visual field processed
superior- lingual
inferior- cuneate
