post- central gyrus
which fissure separates the frontal & parietal lobes from the temporal lobe
lateral fissure
the groove that separates the frontal lobe from the temporal lobe
lateral fissure
the falx cerebri is found within which anatomical feature
longitudinal fissure
what term describes the outermost portion of the cerebrum

lateral fissure
the cerebellum is positioned below what structure
tentorium
which brain stem structure is located inferior to the midbrain and superior to the medulla oblongata
pons
the midbrain adjoins which structure superiorly
thalamus
the pons is primarily recognized by its
semi - spherical shape
the brainstem is the origin for how many cranial nerves
10
the medulla oblongata continues as what structure below the foramen magnum
spinal cord
what cerebral spinal fluid (CSF) passage traverses the midbrain
cerebral aqueduct
the hypothalamus connects to which part of the pituitary gland
posterior lobe
the pituitary gland is located in which bone
sphenoid bone
the pineal gland is primarily associated with what brian structure
epithalamus
the epithalamus includes what endocrine structure
pineal gland
what structure forms part of the lateral wall of the third ventricle
thalamus
the diencephalon is located between which two brain structures
lateral ventricles and midbrain
the thalamus contributes to the formation of what brain structure’s wall
third ventricle
the hypothalamus is involved in connecting to the pituitary gland through which structure
infundibulum
the hypothalamus is involved in connecting to the pituitary gland through which structure
infundibulum
what structure is responsible for circulating CSF around the surface of the brain
subarachnoid space
the cerebral aqueduct connects which two ventricles
third and fourth ventricle
what are the widened areas within the subarachnoid space called
basal cisterns
the subarachnoid space is filled with what fluid
CSF cerebral spinal fluid
what is the function of the median aperture
connects the fourth ventricle to the subarachnoid space
the falx cerebri separates which parts of the brain
two hemispheres of the cerebrum
which meningeal layer is highly vascular and attached directly to the surface of the brain
pia mater
the term “falx” is meningeal extensions refers to
a fold or partition
the space located below the dura mater is known as
subdural space
the falx cerebri extends into which brain structure
longitudinal fissure
the dura maters extension that forms a tent like fold between the cerebrum and cerebellum is called
tentorium cerebelli
the diaphragma sellae covers which bony structure
sella turcica

function of the circle of willis
provide collateral circulation for the brain
the function of the anterior communicating artery (ACOM)
join the anterior cerebral arteries
the middle cerebral arteries (MCA) supply blood to which part of the brain
lateral aspect

anastomosis
which artery provides blood supply to the anterior and medial regions of the brain
anterior cerebral arteries
the basilar artery is formed by the union of which two arteries
two vertebral arteries
the straight sinus is formed by the junction of which two structures
inferior sagittal sinus and great cerebral vein
the inferior sagittal sinus is located along which fissure
longitudinal fissure
which venous pathway in the brain is a large venous cavity lying between the two dural layers of the falx cerebri
superior sagittal sinus
the superior sagittal sinus empties into
the confluence of sinuses
the sigmoid sinuses are named for their
shape resembling a “S”
the inferior sagittal sinus is located along which fissure
longitudinal fissure

internal carotid arteries
which arteries join the posterior cerebral arteries with the internal carotid arteries
posterior communicating arteries (PCOM)
