| Gray matters in the cerebral hemisphere include: | 1. Cortical mantel 2. basal ganglia 3. hippocampus 4. amygdala |
| In the brain, the gray matter is usually stained _________. | yellow |
| In the brainstem/cerebellum/spinal cord, the white matter is usually stained_________ | Purple |
| Different names used for axons: | 1. tracts 2. fibers 3. pathways |
| Collection of nucleus are usually called_________ | Nuclei |
| When the axon crosses the brain, the region of crossing is referred to as ________. | Decussation. |
| When the cell body and synapse are both in the cortex, they are called _________. | Corticocortical neurons |
| The outer area of the cortex that is comprised of cell bodies is called ________. | Cortical mantel |
| T/F: basal ganglia, hippocampus, and amygdala are all collections of cell bodies. | T. |
| The cerebral cortex is made up of ____________ mantel of grey matter. | Laminated |
| What do you name the cerebral cortex that has the following layers: 6 layers <6 layers 3 layers | 6 layers: neocortex <6 layers: paleocortex 3 layers: archicortex |
| The outermost layer of lamina is named -_________. The deepest layer is ________. | Most superficial: Lamina 1. Deepest: Lamina 6. Below lamina 6 is subcortical white matter |
| Corticocortical neurons are mostly found in lamina ______. | II and III |
| Lamina V is mostly __________. | Larger pyramidal cells. |
| Lamina I has mostly ______ and ______. | Axon and dendrites. |
| Lamina VI have pyramidal cells whose axons synapse in the _______, making them _________ neurons. | thalamus. Corticothalamic neurons |
| Corticospinal neurons are mostly found in lamina ______. | V |
| T/F: Lamina II and III are the only output layers in the cortical mantel. | F. Lamina V and VI also are. |
| Which lamina is the 'input' lamina? | Lamina IV |
| ________ fibers are decussation fibers that crosses the cortex. | Commissural fibers |
| ___________ fibers are those that stay in one side of the hemisphere. They run in a -_______ direction. | Association fibers rostral-caudal |
| The projection fibers also stay within one hemisphere. They travel in a ______ direction. | Dorsal-ventral |
| Find the 3 types of fibers in a DTI image of the brain. | See slide |
| T/F：An anxon can only be projection OR commussural fiber, not both. | F. |
| The four places where the commissural fibers travel are called ________ respectively. | Corpus callosum, anterior commissure, posterior commissure, hippocampal commissure |
| Four parts of the corpus callosum from anterior to posterior: | Rostrum, genu, body, splenium |
| Lable the anterior commissure, posterior commissure, and hippocampal commisure | [picture] |
| The _______ is the collection of subcortical white matters as they pass to another cortex. | Internal capsule |
| T/F: Bleeding of 1mm near the cerebral cortex will result in more brain damage than 1mm bleeding in the internal capsule. | F. |
| All 3 areas of the internal capsule can only be seen in the ____ cut. | Horizontal cut |
| In the horizontal cut, _____ is medial to the posterior limb of the internal capsule. | Thalamus |
| Athletes who wear the concussion collar had less damage to their _________, _________, and ______. | Corpus callosum, corona radiata, and internal/external capsule. |
| Lable the thalamic nuclei. | see picture |
| Lable the parts of the lateral ventricle. | Picture |
| The CSF flows from the anterior horn of the lateral ventricles to the ______, pass the ________ and into the _____. It will then leave the ventricle and enter the ________. | The CSF flows from the anterior horn of the lateral ventricles to the [third ventricle], pass the [cerebral aqueduct] and into the [fourth ventricle]. It will then leave the ventricle and enter the [subarachnoid space]. |
| Space _______ become the lateral ventricle. Space of the _______ become the third ventricle. The conduit of mesencephalon becomes the ________. | Space of telencephalon become the lateral ventricle. Space of the [diencephalon] become the third ventricle. The conduit of mesencephalon becomes the cerebral aqueduct. |
| Lable the ventricular structures | See picture. |
| _______ joins the lateral and third ventricle. | Interventricular foramen. |
| The _________ is where the left and right thalamus connect. It is made of ____ cells. | Interthalamic adhesion. Glia cells. |
| The cerebral aqueduct travels through the ________. | Midbrain. |
| ________ and _______ sits ventral to the fourth ventricle. They are the floor of the fourth ventricle. | Pons and rostral medulla. |
| Roof of fourth ventricle is_________. | cerebellum. |
| The fourth ventricle drains into the _______. | Spinal canal. |
| The medial foramen of the fourth ventricle is called _______, while the lateral foramen is called _______. | Medial: Megendie Lateral: Luscka |
| What tissue produces the CSF? | Choroid plexus. |
| The rostral medulla is also called the ______. | Open medulla. |
| The pools of fluid in subarachnoid space are called _____. They are : | Cisterns. Cisterna magna Pontine cistern, Quadrageminal cistern Interpeduncular cistern Lumbar Cistern |
