MODULE 1 Flashcards
where is the wernickes area
POSTERIOR TEMPORAL GYRUS
what is wernickes for
listening and understanding
where is the brocas area
left inferior frontal gyrus
what is the brocas area for
speaking and making words - near premotor cortex
what is the conus medullaris
cone shaped end of spinal cord (L1 and L2)
what is the cauda equina
connections of nerve roots that end under the vertebrae and create a tail
what is the filum terminale
anchors spinal cord within the spinal column
what is the order of layers (in to out) of the spinal cord
pia -> arachnoid -> dural sheath -> epidural space (filled with fat)
what is cuneate in the spine
L6 and up - arms
what is gracile in the spine
L6 and down (legs)
where does a meningitis test come from
the CSF around L2
where does a pregnancy aneasthesia come from
L3-L4 of the epidural space
how many of each vertibrae is there
8, 12, 5, 5, 1
what are the lines in the cerebellum and what do they turn into
arbor vitae, turn into folia
the anterior limb of the internal capsule is between…
between the lentiform abd the caudeate nuclei
which wall of the third ventricle does the hypothalamus form
the inferolateral wall
what does the diencephalon contain
hypothalamus, thalamus and epithalamus
what is the lentiform nucleus made of
putamen and globus palludus
whencoming forward in a coronal slice of the brain which structure becomes more prominant
caudeate nucleus
what is the striatum made of
the putamen and caudeate nucleus
what does the basal ganglia contain
corpus striatum, subthalamuc nuclei and substantia nigra
what is in the corpus striatum
lentiform and caudeate nuclei
where does the basal ganglia recieve connections from
SN and motor cortex (through thalamus)
what is the role of the thalamus
relaying sensory, motor information, cortical arousal, learning and memory
what does damage to the hippocampus cause
neuroendocrine disturbances, autonomic dysfunction, bad temperature regulation and changes to levels of consciousness
what is the flow of CSF
produced in the choroid plexus in each ventricle, goes through CA to the third and into the fourth. after this, there is a medial and lateral aperture for CSF to get into arachnoid space and then into the sinusus via arachnoid granulations
what are the three cisterns and what are they for
interpeduncular, pontine and cerebromedullary. reservoirs of CSF
what are emissary veins
facial skin around the nose and upper lip goes through ophthalamic veins into the cavernous sinus
where does anterior cerebral artery go in the motor cortex
contralateral hemiplegia and damage will be in lower limb
where does the middle cerebral artery go in the motor cortex
upper limb, causes contralateral hemiplegia
what is the function of the temporal lobe
contains areas for sensory reception and integration of sensory information
what is the parietal lobe responsible for
sensory reception and integration of the information
frontal lobe functions
voluntary motor functions, language, planning, mood, personality, social judgement and smell
what does the thalamus do
integrate the cerebral cortex into the rest of the features of the brain
what does the hypothalamus do
homeostatic roles of all different parts of the body
what does the epithalamus do and contain
attached to roof of third ventricle, contains calcium salts in adults. makes MELATONIN
