This video will go over the parts of the brain. So right here we have our cerebral hemisphere, right cerebral hemisphere. This is the cerebellum, brainstem, diencephalon. Within the cerebral hemisphere, we are going to have your corpus callosum, which is made up of... tracts that connect the right and left cerebral hemispheres.
We have a group of tracts here called the fornix, and between the corpus callosum and the fornix is your right lateral ventricle that will be covered by the septum pellucidum. Here in the circular area, we have the thalamus, and within the thalamus, we have the intermediate mass. Below the thalamus, we have the hypothalamus. And above the thalamus, we have the epithalamus. And that edge right there is the penile gland.
Altogether, the hypothalamus, thalamus, and epithalamus are going to be covered by the third ventricle. This area right here is the entire The back of the midbrain is known as the tectum or capora quadrigemina. It's composed of two bumps. The top is the superior colliculi. Bottom is the inferior colliculi.
Below the midbrain we have the pons. Below the pons we have the medulla oblongata. The midbrain, pons, and medulla all make up the brain stem. Right below the medulla, we have our spinal cord, and we can see this thin line right there. That's representing the central canal of the spinal cord.
The central canal of the spinal cord runs right into the fourth ventricle, and the fourth ventricle is connected with your third ventricle by this canal called the cerebral aqueduct. Here is your cerebellum. The white branches are arbor vitae, also known as cerebellar tracts. And then surrounding the arborvitae are the folia, which is gray matter, and the gray matter is known as cerebellar cortex. In the ventricles, what we're going to have is CSF, cerebrospinal fluid, circulating.
All of these noodles are known as giri, and all of these indentations are known as sulci, or a singular sulcus. When you look at very specific areas, they're all going to have their own name to them. So I like to use a different model to see the ones that you will need to learn. You can see this very defined sulcus right here.
This is known as your central sulcus. And before your central sulcus is the precentral jury, postcentral jury. Then you have your lateral sulcus right here. All of this is your frontal lobe, parietal lobe, temporal lobe, and in the back is your occipital lobe above the cerebellum. When we put two of these together, We can see that where the cerebellum comes together is kind of a little worm.
So this is the left cerebellar hemisphere and the right cerebellar hemisphere. And between them is the vermis that holds it together. And then from the top view, we have our longitudinal fissure which separates the right and left cerebral hemispheres.
