Inside the Brain Practical Flashcards
What separates the occipital and parietal lobes
The parieto-occipital sulcus
Describe the order of the pons, midbrain, medulla
Thalamus, midbrain, pons, medulla
Where is the third ventricle
In the midline in the cerebral hemispheres
Where is the fourth ventricle
Lies posterior to the pons and upper medulla
Where are the lateral ventricles
In each of the cerebral hemispheres
What is CSF secreted by
Choroidal epithelial cells in the choroid plexus
Where would you find CSF after it has flowed out of the ventricular system
CSF flows from teh ventricles to the subarachnoid space and then to dural venous sinuses
Where and by what structure is CSF resorbed
At the dural sinuses by arachnoid granulations
Describe Weighert method
Stains lipids/fats darkly (brown/ black/ charcoal) which means that any area stained darkly contains lipids so are all myelinated.
What do the darkly stained areas immediately below the cerebral cortex represent
Efferent and afferent axons (going in and out of the cortex)
Describe the lentiform nucleus
Consists of internal globus pallidus and external globus pallidus, putamen and claudstrum
What is the function of the occipital lobe in the cerebral cortex
Sensory vision
Describe the hippocampus
Rolled-up region of cerebral cortex lying in the floor of the inferior horn of the lateral ventricle in the temporal lobe.
What is the fornix
White matter that conveys efferent output from the hippocampus
What is the hippocampus responsible for
Long term memory
