|
Subthalamus |
Between the thalamus and the hypothalamus not reaching the surface (2nd smallest division) |
|
|
Thalamus |
The superior dorsal portion, largely obscured by the cerebral hemisphere( largest division) cns sensory relay |
|
|
Hypothalamus |
Inferior ventral portion of the diencephalon 2nd largest division
regulates body temp water emotions, ans) |
|
|
Epithalamus |
On the dorsomedial edge of the thalamus( smallest division) |
|
|
Interpeducles fossa |
Between the interpeduncle fossa and appears as a large depression |
|
|
Corpora quadrigemia |
In center of the midbrain are corpora quadrigemia which are composed of inferior colliculi and superior colliculi |
|
|
Cerebellar peduncle |
Is a large bulging mass of white matter axons on the anterior surface of the pons that carry info to the cerebellum |
|
|
What is CSF |
*produces choroid plexus, is clear, colorless *it replaces 3xs a day *circulates from ventricles to subarachnoid space around cns *protects brain n spinal cord *enter subarachnoid space from 4th ventricle thru 3 apertures or holes *reabsorbed thru one way opening called arachnoid granulations. |
|
|
Cerebral peduncles |
In the midbrain large nontegmental area on either side of the anteron lateral part of midbrain. |
|
|
Cerebral cortex |
Sheets of gray matter that covers all the gyri and sulci. Deeper in the cortex lies broad sheets of white matter and still deeper nuclei |
|
|
Brodmann 44/45 |
Location- edge of frontal lobe at lateral fissure in the area triangular
function: broca area- controls expressive speech left side
|
|
|
Brodmann 4 |
Located in Precentral gyrus
function: primary motor cortex (initiates voluntary movements) |
|
|
Brodmann 40/39 |
Location-super marginal gyrus and angular gyrus arches over the lateral sulcus
intergrate vision and touch like reading and writing |
|
|
Brodmann 41/42 |
Location spread open the lateral fissure you can see the heschls gyrus transverse gyri of heschl
primary auditory cortex |
|
|
Brodmann 17 |
Located- occipital lobe the gyri just above and just below the calcareine fissure form primary visual cortex
visual processing |
|
|
Brodmann 22 |
Location- poster 2/3 of superior temporal gyrus is the wernickles area
receptive speech-decoding |
|
|
Brodmann 3 1 2 |
Location post central gyrus
primary somatosensory touch, pressure,temperature, pain |
|
|
Folia |
Latin leaf it is covered by 3 layers of gray matter that come together are cerebellar cortex |
|
|
What the Precentral gyrus |
Large gyrus anterior to the central sulcus is the Precentral gyrus |
|
|
Control sulcus |
Extends dorsal and lateral and ends at the lateral sulcus |
|
|
The frontal lobe is anterior to the------parietal is posterior to ---------inferior to -------------is the temporal lobe and occipital lobe |
Central sulcus central sulcus lateral fissure |
|
|
Frontal lobe |
Coordinates skilled motor movements and cognitive function |
|
|
Medulla |
Contains descending and spending fiber tracts to nuclei of cranial nerves.
viii vestibular-cochlear ix x xi xii |
|
|
Fornix |
Fiber tract under corpus callosum |
|
|
Where is the corpus callosum |
Center midline of cerebrum inferior to mid longitudinal tissue |
|
|
Splenium |
Posterior part is the thickest |
|
|
Corpus callosum |
Large fiber tract of white matter meek indicated axon that connect almost all parts of left hemisphere to almost all parts of right |
|
|
Basilar artery |
Gives off anterior inferior cerebellar Arteries acia superior cerebellar arteries
terminate at the upper pons and separates into 2 posterior cerebral arteries. This simple the posterior cerebral hemisphere occipital ventral medial portion of temporal |
|
|
ACIA |
Supplies parts of medulla pons and anterior inferior portion of cerebellum |
|
|
travels up neck and enters at foramen magnum in the base of skull division point for spinal and medulla of brain stem |
Vertebral arteries |
|
|
Carotid arteries |
Travels up neck enters at level of hypothalamus the larger of the 2 groups and carries the majority of blood supply. |
|
|
