VERIFIED ANSWERS🔰 ✔✔Brain, spinal cord, and proximal nerve roots
The three tissue layers enveloping the brain - ** VERIFIED ANSWERS🔰 ✔✔1) Dura
Mater-outermost layer, strongest and thickest
2) Arachnoid Mater - thin membrane enclosers the subarachnoid space
3) Pia Mater - innermost layer, follows contour of cortex, composed of 2 layers highly
vascular and sheaths blood vessels as they enter brain
CSF filled pace between the arachnoid mater and pia mater. Contains CSF bridging veins
that travel over the surface of the CNS. - ** VERIFIED ANSWERS🔰 ✔✔Subarachnoid
space
Where the primary motor cortex (Brodmann's area 4) is located in the brain - ** VERIFIED
ANSWERS🔰 ✔✔In the precentral gyrus in the frontal lobe. It is the cortical area from
which movements are most easily elicited and the source of about a third of the coricospinal
tract
Where the motor speech are (Broca's area) is located in the brain - ** VERIFIED
ANSWERS🔰 ✔✔In the inferior frontal gyrus in teh frontal lobe usually on the left side
Where the primary somatosensory cortex is located in the brain - ** VERIFIED
ANSWERS🔰 ✔✔In the post central gyrus of the parietal lobe
,Where the receptive speech area is located in the brain - ** VERIFIED ANSWERS🔰 ✔✔In
the suramarginal and angular gyri of the parietal lobe, also includes adjoining regions of the
temporal and occipital lobes
What the corpus collosum interconnects - ** VERIFIED ANSWERS🔰 ✔✔Commisure that
connects the right and left cerebral hemispheres
The brainstem is composed of these main structures - ** VERIFIED ANSWERS🔰
✔✔Contains nuclei for most of the cranial nerves and connects critical pathways in the
brain and spinal cord to the entire body. It is subdivided into the
1) Medulla
2) Pons
3) Midbrain
The central sulcus is the boundary between these two lobes - ** VERIFIED ANSWERS🔰
✔✔The central sulcus (fissure of Rolando) is the bondary between the frontal and parietal
lobes, and the transition zone between primary motor and primary somatosensory cortex
The Basal Ganglia is composed of - ** VERIFIED ANSWERS🔰 ✔✔A group of subcortical
nuclei, most prominently ibncluding the putamen, globus pallidus, and caudate nucleus
Where the primary visual cortex (Brodmann's are 17) is located - ** VERIFIED
ANSWERS🔰 ✔✔In the calcarine sulcus
This artery supplies blood to the anterior and middle cerebral arteries - ** VERIFIED
ANSWERS🔰 ✔✔The Internal Carotid Artery
This large vessel is formed by the union of the two verterbral arteries - ** VERIFIED
ANSWERS🔰 ✔✔The Basilar Artery
,This larege artery is formed by the bifurcation of the common cartotid artery - ** VERIFIED
ANSWERS🔰 ✔✔The Internal Carotid Artery
These arteries account for most of the blood supply to the brain - ** VERIFIED
ANSWERS🔰 ✔✔The two internal carotids account for 85% of cerebral blood flow and thus
supply most of the blood to the brain
The middle cerebral artery supplies to these areas of the brain - ** VERIFIED ANSWERS🔰
✔✔It supplies the insula, most of the lateral surface of the cerebral hemisphere, and the
anterior tip of the temporal lobe
The anterior cerebral artery supplies to these areas of the brain - ** VERIFIED
ANSWERS🔰 ✔✔It supplies the frontal lobes and medial aspect of the parietal and occipital
lobes
The posterior cerebral artery supplies to these areas of the brain - ** VERIFIED
ANSWERS🔰 ✔✔It supplies the rostral midbrain, posterior thalamus, medial occipital lobe,
and inferior and medial surfaces of the temporal lobe
Where the vertebral artery enters the brain - ** VERIFIED ANSWERS🔰 ✔✔The vertebral
artery originates at the first branch of the subclavian, runs cranially through foramina in
cervical vertebrae C6, enters the base of the skull through the foramen magnum and
ascends along the medulla
These arteries constitute the Circle of Willis - ** VERIFIED ANSWERS🔰 ✔✔The Circle of
Willis consists of parts of the internal carotid artery, the anterior and posterior cerebral
arteries, interconnected by the anterior and posterior communicating arteries
Structure that makes collateral circulation to the brain possible due to a vascular
anastomosis at the base of the brain - ** VERIFIED ANSWERS🔰 ✔✔The Circle of Willis
, The interventricular foramen is also known as this - ** VERIFIED ANSWERS🔰 ✔✔Also
known as the Foramen of Munro
The aqueduct of sylvius (aka cerebral aqueduct) connects these two ventricles - **
VERIFIED ANSWERS🔰 ✔✔Connects the third and fourth ventricles
The opening between each lateral ventricle and third ventricle - ** VERIFIED ANSWERS🔰
✔✔Foramen of Munro (aka interventricular foramen)
CSF is mainly produced by this structure - ** VERIFIED ANSWERS🔰 ✔✔By the choroid
plexus in the lateral, third and fourth ventricles
These 2 openings allow CSF to flow into the subarachnoid space? - ** VERIFIED
ANSWERS🔰 ✔✔The foramina of Luschka, and the foramen of Magendie
Where absorption of CSF into the blood stream takes place - ** VERIFIED ANSWERS🔰
✔✔In the superior sagittal sinus through structures called arachnoid villi
Pathway for flow of CSF through the ventricular system - ** VERIFIED ANSWERS🔰
✔✔Lateral Ventricles - Interventricular foramen - Third Ventricle - Cerebral Aqueduct -
Fourth Ventricle - Lateral and Median Apertures - Subarachnoid Space - Arachnoid Villa -
Subdural Sinus - Venous Blood
The main function of CSF - ** VERIFIED ANSWERS🔰 ✔✔Main function is to protect the
brain and spinal cord by acting as a shock absorber. It is contained in the 4 ventricles, the
subarachnoid space and the central canal of the spinal cord
Definition of hydrocephalus - ** VERIFIED ANSWERS🔰 ✔✔Hydrocephalus means "water
on the brain" and occurs when there is an increase in the volume of CSF. Due to the closed
skull there is no place for CSF to expand, if pressure becomes too high the brainstem is
forced to try to escape through the foramen magnum
