Cerebellum with pons and medulla oblongata.
Medulla oblongata is the lower portion of the brainstem. This structure controls processes such as breathing and blood pressure.
In humans and other bipeds, pons are above the medulla, below the midbrain, and anterior to the cerebellum.
The pons in humans measures about 2.5 cm or 1 inch in length. Most of it appears as a broad anterior bulge rostral to the medulla

I'm sorry if this comes across as "douchey." This is the cerebellum with the pons attached at the top. If the medulla is there, it is not visible because it would under (inferior to) the cerebellum. The pons does have an important role to play in breathing, but the cerebellum is mostly concerned with coordinated movement and skills learning. Okay, academic baggage unpacked.
ReplyDeleteThis is the inferior view of the brain and the picture is not that detailed to point out the medulla or the pons. Frankly the pons don't look like this, and we don't know how much of the pons or medulla was sliced, the top part looks more like medulla. Anyways, thx for the academic samsonite =)
ReplyDeleteCorina Marinescu My apologies if I've misinterpreted the image. To me, it really looks like a superior view. The cross section of the brain stem there looks much more like a pontine section than a medullary section, too. I would expect a significant bulge from the inferior olive rather than a strong white matter base. (I suppose any comment that I start with apologizing for sounding "douchey" is a comment I shouldn't make to begin).
ReplyDeleteWhat? No...I already said thanks for the Samsonite..and I wasn't being sarcastic Brandon Poe =)
