T/F A gyrus is a deep groove located in the cortex
T/F Broca's area (Brodmann area 44) is located in the frontal lobe and is responsible for receptive language
T/F Wernicke's area (Brodmann area 22) is located in the temporal lobe and is responsible for receptive language
T/F Lesions to the supramarginal gyrus in the parietal lobe could result in deficits with reading, writing, and language
The ___________ is located deep within the lateral (Sylvian) fissure, underneath the opercula of the frontal, parietal, and temporal lobes.
The primary motor cortex and the primary sensory cortex are located in which lobes, respectively?
frontal lobe, parietal lobe
The major language association area is located in which lobe?
T/F The outermost cerebral meninge is the pia mater
The dura mater consists of how many layers?
What are the names of the external and internal layers of the dura mater, respectively?
T/F The subarachnoid space is located between the arachnoid and pia mater and is filled with CSF
Which cerebral meninge is attached to the surface of the brain?
Which cerebral meninge is composed of fibrous connective tissue and provides the most meningeal protection to the CNS?
T/F Dissection of the sheep brain along the longitudinal fissure is considered cutting along the coronal plane
T/F Removal of the sheep brain dura mater was needed in order to access the cerebrum
T/F The most rostral component of the brainstem is called the pons
The diencephalon is composed of the
thalamus and hypothalamus
The cerebellum is made up of two hemispheres, similar to the cerebrum.
The classic sign associated with a cerebellar impairment is
Patient with a cerebellar lesion may experience
dysmetria and a wide-based gait & ataxic dysarthria
T/F The neurotransmitter imbalance seen in Parkinson's disease is not enough dopamine (DA) and too much acetylcholine (ACH)
The primary function of the basal ganglia is to
regulate motor control and muscle tone
The movement disorder associated with Huntington's disease is
The neurotransmitter imbalance associated with Huntington's disease is
too much dopamine
The pyramidal decussation, where all descending motor fibers decussate, is located in which region of the brainstem?
T/F The spinal cord is covered in protective meninges; dura, arachnoid, and pia
The central nervous system does NOT include
cranial and spinal nerves
T/F The circle of Willis plays an important role in supplying oxygenated blood to the brain. Occlusions above the circle are likely to result in brain damage
T/F The circle of Willis plays an important role in supplying oxygenated blood to the brain. Occlusions below the circle are likely to result in brain damage
The lateral surface of the frontal lobe receives vascular supply from which artery?
T/F Arteriorvenous malformations are always developed later in life and rarely cause any complications
The branches of lenticulostriate arteries are a common place for cerebral vascular accidents because they are
at right angles anatomically
T/F Ischemic stroke occurs when a blood vessel ruptures and there is bleeding into the brain
T/F The blood from the brain drains through cerebral veins and ultimately empties into the internal jugular veins
T/F Veins have valves so they can pump blood back to the heart
The superficial cerebral veins drain into the superior sagittal sinus
superior sagittal sinus
The function of the deep cerebral veins is to
drain blood from subcortical structures
middle meningeal vein bleeds tend to form
headache is referred to the skin of the forehead and face because
pain receptors in the dura above the tentorium send their impulses via the trig
the flax cerebra is a dural reflection that
extends longitudinally in the inter hemispheric fissure & forms a vertical separation between two cerebral hemispheres
the pia mater is
vascular & a thin collagenous membrane & attached to the brain & follows the contour of the gyri and sulci
the dura mater consists of two fibrous layers that
are attached to each other & separate to form sinuses that absorb venal blood
a torn meningeal artery is most likely to cause bleeding into
real spaces within the cranium include
a wide based gait and jerky movements are associated with damage to the
characterizes a contralateral tract
functional deficits are opposite the injured side & it decussates
