Question | Answer |
What does the central (rolandic) fissure separate? | The frontal and parietal lobes |
What does the lateral (sylvian) fissure separate? | The parietal and temporal lobes |
What are Gyri and Sulci? | Gyri are folds, Sulci are small grooves (as opposed to fissures) |
What is the Precentral Gyrus also known as, and where is it located? What does it do? | AKA Motor Strip, and located just anterior to the rolandic fissure. Gives rise to contralateral motor impulses. |
What does the postcentral gyrus do? | Sensory input via peripheral sensory nerves from spinal cord thru thalamus |
What is the Lateral Spinothalamic Tract for? Where does it cross? What happens with lesion? | Sensing pain/temp; crosses immediately in spinal cord, lesion results in loss of pain/temp contralaterally below lesion |
What is the Anterial Spinothalamic Tract for? Where cross? With lesion? | Sensing light touch, cross immediately in spinal cord, lesion results in loss of light touch contralaterally below lesion |
What are the Posterior Columns for? Where do they cross? What happens with lesion? | Sensing vibration, proprioception, stereognosis. Cross at intersection between spinal cord and brain stem. Lesion results in loss of these abilities ipsilaterally. |
What is the Anterior/Posterior SpinoCerebellar Tract for? What happens with lesion? | Senses unconscious proprioception. Lesions always result on deficit ipsilaterally. |
What is the Anterior/Lateral Corticospinal Tract? Where does it cross? What does it divide? | These are descending motor tracts which cross where brain and spinal cord meet. Divides neurons into Upper and Lower Motor Neurons. |
What are the structures that make up the Limbic System? | Hippocampus, Amygdala, Thalamus, Hypothalamus, Cingulate Gyrus |
What cranial nerve(s) is/are the midbrain associated with? | CN III and CN IV |
What cranial nerve(s) is/are the pons associated with? | CN V |
What crainal nerve(s) is/are associated with the medulla? | IX, X, XII |
Where are the points of synapse for the thalamic synapses? | Ventropostlateral Nucleus (VPL)Ventroposteromedical Nucleaus (VPM) - synapses for spinothalmaic tract |
Where does the Optic Tract synapse? | Lateral Geniculate Bodies |
Where does the Auditory Tract synapse? | Medial Geniculate Bodies |
