Anatomy Flashcards
bridging veins: from where to where? what kind of hemorrhage is torn?
from subarachnoid and subdural space to SSS. Subdural hematoma
arachnoid granulations
punch through dura to allow csf to get into bloodstream
CSF pathway
lateral vent>intervent foramina of monro>3rd ventricle>cerebral aqueduct>4th>foramina of magndie and luschka>subarachnoid space>granulations>SSS
auditory gyrus? speech center?
heschl’s gyrus. Broca’s area (opercular part, triangular part)
what is behind the lamina terminalis
third ventricle
gray matter b/w optic chiasm and mamillary bodies
tuber cinereum
from dorsal median sulcus (med>lat)
superior: obex, foramen of magendie. Gracile tubercle, cuneate tubercle (and fasciculis gracilis, fasciculis cuneatus)
fissures of superior cerebellum
primary (anterior), posterior superior, horizontal, posterolateral
what is just anterior to the posterolateral fissure?
flocculus
what is on either side of the cerebral aqueduct
Tectum (post) and tegmentum (ant)
what make up the floor and roof of the 4th ventricle
the superior and inferior medullary vellum
lobes and fissures of cerebellar vermis clockwise
lingula, central, culmen, primary fissure, declive, folium, horizontal fissure, tuber, pyramis, uvula, posterolateral fissure, nodulus
features of the rhomboid fossa of fourth ventricle
median sulcus, sulcus limitans, medial eminence, hypoglossal and vagal trigones, calamus scriptorius with obex and area postrema
the little lines of the cerebellum are called
folia
where sup and inf medullary velum meet
fastigium
flocculus
just outside of foramen of luschka
medial view of brian, name major gyri, sulci, areas from post to ant
lingual gyrus, calcarine sulcus, cuneus, parieto-occipital sulcus, precuneus, marginal sulcus, paracentral lobule
parts of fornix
fimbria, crus, body, column (with pre and post commisural fibers)
parts of lentiform nucleus. What tracts surround them?
globus pallidus, putament; internal capsule, external capsule, claustrum, extreme capsule
On coronal plane, when does the genu turn into the body of CC?
when you start to be able to see int capsule (NOT rostrum of CC)
when does head of cuadate become body of caudate
section 5 (thru mamillary body)
where is the basal forebrain
right below the anterior commissure
when do you see the hypothalamus and the subthalamic nucleus
where you begin to see thalamus
section 5 thru lentiform nucleus from medial to lateral
internal segment of globus pallidus, medial medullary lamina, external segment, lateral lamina, putamen
cerebellar peduncles from lateral to medial
middle, inferior, superior
