I know the Cerebellum has 3. Lobes.

I wanted to ask the 3. Superior Peduncles that come from the Midbrain do they go to all 3 Cerebellum Lobes?

Also Does the 3. Middle Peduncles that come from the Pons go to all 3. Cerebellum Lobes?

Also does the 3. Inferior Peduncles that come from the Medulla go to all 3. Cerebellum Lobes?

Hi biferi (https://biology-forums.com/index.php?action=profile;u=1259102)

All afferent and efferent fibers of the cerebellum pass through the three peduncles (and the pons) to the other levels of the nervous system.

The superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain. The middle cerebellar peduncle connects the transverse fibers of the pons with the cerebellum, which is entirely afferent to the cerebellum.

I am sorry I should have asked this way to keep it easy for me to understand?

The Middle Peduncles go from the Pons to what Cerebellum Lobe?

Anybody?

The middle cerebellar peduncle connects the transverse fibers of the pons with the cerebellum

You say the middle cerebellar peduncle connects the transverse fibers of the pons with the cerebellum.

I think I understand a little more please tell me if I have this Right?

The middle cerebellar peduncle going to the Pons do they have in them the Inferior peduncle that go the Medulla?

No, the middle cerebellar peduncles and the inferior cerebellar peduncles are two separate structures of the cerebellum and brainstem that serve different functions.

The middle cerebellar peduncles are a pair of thick bundles of nerve fibers that connect the cerebellum to the pons in the brainstem. They are located on the lateral aspect of the brainstem and serve as the main input pathway to the cerebellum from the cerebral cortex. On the other hand, the inferior cerebellar peduncles are also a pair of thick bundles of nerve fibers, but they connect the cerebellum to the medulla oblongata in the brainstem. They are located on the posterior aspect of the brainstem and serve as the main input pathway to the cerebellum from the spinal cord, vestibular nuclei, and other brainstem structures. Thus, the middle cerebellar peduncle and the inferior cerebellar peduncle are distinct structures that do not contain each other.

Well when you say the Inferior Peduncles go from the Medulla to the Cerebellum I get this.

The Cerebellum is made of 3. Lobes so when you say the Inferior Peduncles go to the Cerebellum I keep thinking witch Lobe?

Or what am I missing?

I think I am getting a little closer to understanding?

The 3. Inferior Peduncles go from the Medulla to the Cerebellum Flocculonoduar Lobe.

This gives a path for the Cerebellum Flocculonoduar Lobe to the Spinal Cord.

Do I have just this part Right?

Specifically, the Inferior Peduncles connect to the flocculonodular lobe, which is the most inferior part of the cerebellum and is involved in balance and eye movements.

Does the paths from flocculonodular lobe going to the Spinal Cord?

Yes, it is connected to the spinal cord. The flocculonodular lobe receives input from the vestibular system. Its output projects through the inferior cerebellar peduncle to the vestibular nuclei, which in turn send fibers to the spinal cord to control balance and posture. Thus, the pathways from the flocculonodular lobe to the spinal cord are part of the vestibulospinal tract.,

Am I Right the Middle Peduncles going to the Pons give a Pathway for the Right and Left  Cerebellum Lobes Hemisphere to talk togather?

Sorry for the late reply. Yes, that's correct 👍

So because the Cerebellum has 3. Lobes on the Left and Right side I understand this is 2. Hemispheres.

I understand the Middle Peduncles going to the Pons give a Pathway for the Right and Left  Cerebellum Lobes Hemisphere to talk togather.

Because the Middle Peduncles are just 3. does each on split into 2. so it can go to both the Right and Left  Cerebellum Lobes Hemispheres?

That I am not 100% sure of this, but I am more certain that the answer is NO, it does not split.

Does anybody here now how the 3 Middle Peduncles go to all 3.  Cerebellum Lobes on the Left and Right side to give a path for both Hemispheres to talk to the Pons?

The member who posted earlier is right, the middle peduncles of the cerebellum does not split to the cerebellar hemispheres. The middle peduncles are part of the cerebellar peduncles, which are a set of three bundles of nerve fibers that connect the cerebellum to the rest of the brainstem. The middle cerebellar peduncles connect the cerebellum to the pons, a part of the brainstem that lies just above the medulla oblongata. These fibers carry information from the cerebral cortex to the cerebellum, providing the cerebellum with input about motor commands that are about to be executed. The cerebellum then processes this information and sends feedback to the cerebral cortex to refine and adjust the motor commands as needed.

Let me ask this?

The 3. Inferior peduncles coming from the Medulla go to the cerebellum Flocculonodular Lobe.

The cerebellum Flocculonodular Lobe has 2. Lobes Right?

How does all 3. Inferior peduncles go to just 2. cerebellum Flocculonodular Lobes?

Post Merge: A year ago

How can I find out this?

I know the Middle Peduncles go from the Pons to the Cerebellum.

I know the Inferior Peduncles go from the Medulla to the Cerebellum.

If the Middle Peduncles just have 3. fibers and the Inferior Peduncles just have 3. fibers how does each pair go to all 3. Cerebellum Lobes on each side?

It consists of two parts: the flocculus and the nodulus, but they're not lobes. The Inferior peduncles connect to the flocculonodular lobe of the cerebellum at its lowermost part.

Before I can answer further, let's make sure we're clear on this first...

I think I understand the Flocculonodular Lobe is 1. big Lobe Right?

Yes, it's nonsegmented

Ok this I understand.

Now just talking about the Middle Peduncles .
They are 3. Fibers that go from the Pons to the cerebellum.

Witch of the 3. cerebellum Lobes do these go to?

I'm not understanding this question. Who says that there are exactly three fibers that go from the Pons to the cerebellum? This is very confusing...

I Watched a Video a long time ago that says the Peduncles are pairs of 3. fibers.

So let me see if I have this Right.

There is just 3. Cerebellum Peduncles and they all come from the Cerebellum.

One Peduncle goes to the Midbrain.
One goes to the Pons.
One goes to the Medulla.

Do I have this Right now before I go on?

Thanks for the help.

Correct :)

Now the Middle Peduncle goes to the Pons but what Cerebellum Lobe does it come from?

I'll be a little more specific

The middle cerebellar peduncle connects the cerebellum to the pons. Specifically, it connects the pons to the cerebellum, with fibres originating from the pontine nucleus and travelling to the opposite hemisphere of the cerebellar cortex.

An illustration is here: https://biology-forums.com/index.php?action=gallery;sa=view;id=37660

The Photo you posted does show all the parts of the Brain.

I think I have this now?

Just the middle peduncle go from the Pons and split off into every part of the Cerebellum.

Is just this Right?

TRUE :)

The fibers of the middle cerebellar peduncle split off into every part of the cerebellum, providing a major pathway for communication between the cerebellum and the rest of the brain.

So the Pons has 1. peduncle coming off it.

This peduncle splits and has 1. fiber going to every cerebellum lobe.

This is how the Left and Right cerebellum lobes talk to each other.

Is this Right?

Is just this Right?

The pons itself is anatomically connected to the cerebellum through three pairs of cerebellar peduncles. These peduncles are the superior cerebellar peduncle, the middle cerebellar peduncle, and the inferior cerebellar peduncle. The superior cerebellar peduncle connects the cerebellum to the midbrain, the middle cerebellar peduncle connects the cerebellum to the pons, and the inferior cerebellar peduncle connects the cerebellum to the medulla oblongata.

I think I have it now?

Tell me witch one I am still not getting?

The Inferior Peduncle goes from the Medulla and goes to the Focculonoduar cerebellum lobes it this Right?

The Middle Peduncle goes from the Pons the splits off to every cerebellum lobes is this Right?

Just tell me if I have these 2. things Right?

If I do not understand these 2. thing then I will not go on till I get it.

Its already been explained countless times in this thread. :grumpy:
