quiz #2 - brain Flashcards
structures that develop from the telencephalon
cerebral hemispheres, basal nuclei, lateral ventricles
meningeal layer that is the most external in the cranium
dura layer
key difference between cranial and spinal meninges
cranial dura has 2 layers
spinal dura only has 1 layer
large artery that supplies posterior brain
vertebral artery
T/F - circle of Willis ensures that CSF can reach entire brain, even if one route is blocked
FALSE
functions of hypothalamus
-controls autonomic nervous system (ANS)
-coordinates between nervous system & endocrine system
-regulates hunger, thirst, & feelings of satiety (produces hormones)
what structure secretes melatonin
pineal gland
hypothalamus does NOT
what is significant about the superior & inferior colliculos of the midbrain
visual, auditory & startle reflex processed here
the ascending portion of the reticular formation is called
the…
reticular activating system
the largest motor tracts of the body form two bulges in the medulla oblongata & decussate here - these are called…
pyramids
region of cerebellum that governs equilibrium & balance
flocculonodular lobe
deep valley that separates the left & right hemispheres is called ____, while the white matter which connects them is called the____
longitudinal fissure
corpus collosum
CSF is produced in the _____ of the ventricles and is gradually reabsorbed though the _____
choroid plexus
arachnoid villi
where does the cerebrospinal fluid flow
subarachnoid space (SAS)
diencephalon gives rise to…
thalamus, hypothalamus, epithalamus
part of the brainstem is a functional network of neuronal cell bodies & small bundles of myelinated axons which travel through all parts of the brainstem & has an important function in sleep & arousal
reticular formation
an important function of this part of the brain is to help regulate initiation & termination as movements
basal nuclei
in hemispheric lateralization, which characteristics is the left hemisphere more associated with
reasoning, math, science, written language, sign language
brain waves indicate that someone is having a deep, dreamless sleep
delta waves
neurological term describes anatomical changes in neurons when they are stimulated
neural plasticity
the better type of rehearsal to move information from short term to long term memory is…
elaborative rehearsal
main motor control of the body
frontal lobe
main sensory output to the body
parietal lobe
function of the temporal lobe
hearing (audition)
function of the occipital lobe
vision
sensory relay to other parts of the brain
thalamus
limbic system
emotions
structure that carries CSF from 3rd to 4th ventricle
cerebral aqueduct
separates primary motor area from primary sensory area
central sulcus
part of the brain deep inside the cerebrum, sometimes called the fifth lobe, & aids in motor control, homeostasis and interception
Insula
an example of a commissural tract (conducts nerve impulses from one hemisphere to another)
corpus callosum
