Sheep Brain - Internal gross anatomy

Corpus callosum (Internal view):
Sagittal section/view of Corpus callosum. The Corpus callosum is the "roof" of the Lateral ventricles (1st and 2nd ventricles).


  
Rostrum (of Corpus Callosum):
Rostrum forms the "anterior wall" of the Lateral ventricles ("1st and 2nd ventricles").

Lateral ventricles (aka "1st and 2nd ventricles"):
Sagittal section/view of Lateral ventricles (only 1 side shown here); Lateral ventricles are the 1st and 2nd "cavities" in the cerebrum.

Alternate photos for the lateral ventricles (1 per lobe in the cerebral hemisphere).


Septum pellucidum: no picture because this structure is not visible in the sheep brain; it is the "flap" of tissue that separates the Lateral ventricles internally.


Fornix:
Fornix is the "floor" of the Lateral ventricles (aka 1st and 2nd ventricles) of the Cerebrum.


Pineal gland:
Pineal gland is a round piece of tissue that sits (approximately) in the center of the brain, located underneath the Fornix. Here is a link to a clearer Sagittal section that shows the location of the Pineal gland.


Thalamus:
Thalamus is the big "bump" of  brain tissue indicated by probe. Thalamus is located immediately anterior to the Pineal gland and immediately inferior to (below) the Fornix.

Third (3rd) ventricle: no clear picture from class. Here is a link to a clear Sagittal section/view of the 3rd ventricle in the sheep brain.


Cerebral (Mesencephalic) Aqueduct:
Sagittal section/view of Cerebral aqueduct ("of the midbrain") of Specimen 1.

Sagittal section/view of Cerebral aqueduct of Specimen 2.


Fourth (4th) ventricle:
Sagittal section/view of the 4th ventricle of Specimen A; 4th ventricle is the thin cavity located immediately adjacent and posterior to the 3rd ventricle, and immediately inferior to the cerebellum of the sheep brain.

Sagittal section/view of the 4th ventricle of Specimen B.

  2. Looking for natural medicine to pineal cyst without any side effect Dr. Williams is the best because it has no side effect, After my son being diagnosed of pineal cyst in 2010, I have used numerous medicine for him with no improvement. He spent most of the summer in the hospital. I remember him feeling abandoned and terrified of the many injection needles that seemed necessary to keep him calm. All Western Medicine used in the past did not have any noticeable difference,one day as i was going through the internet i came across so many people with different disease testifying about dr williams herbal remedies,i ordered for my son pineal cyst on line through dr williams,that's when he started using dr williams Herbal Medicine,and now is completely cured from pineal cyst , his medicine is really a permanent cure to pineal cyst, for more info contact (drwilliams098675@gmail.com for advice and for his product

  3. I recently have some difficult conversations and I did what a lot of people do when they want to know more about something. I googled it. I came across Dr Williams herbal medicine on YouTube so many people thanking him about his good work. I also have pineal cyst. I wasn’t running all over God’s creation with every man I could find but here I am. I have felt bad about myself for so many years now because of my pineal cyst status. I obviously still have some self-accepting to do but I want to thank Dr Williams for everything he have done for my life ,after taking Dr Williams medicine i was completely free from pineal cyst within one month of usage, I think what you are doing is so admirable. you have helped me a lot! I want to definitely reach out to you and thank you for your amazing work. You are a good person, and an extremely talented man. You have helped millions with your herbs, and have really inspired me,and i pray you still continue doing the good work.you can also email him on drwilliams098675@gmail.com for help
